Executive Summary

Preamble

1.1 Numbers of new sugar factories have increased in the nearby area of The

Ugar Sugar Works ltd., and also existing sugar plant expansions are taking

place in the nearby area. Hence the total cane crushing capacity is

increasing in the same cane growing area, which in turn reduces the

duration of crushing days. To maintain the ultimate sugar production target

it is essential to increase the crushing capacity of USWL. At the same time

expansion of cogeneration and distillery is also essential to balance the by-

products. In this line of action management of ugar sugar have decided to

go for Sugar Plant expansion in phased manner. It is proposed to expand

sugar plant capacity to 20000 TCD, cogeneration 76 MW and distillery to

200 KLPD. Before going into details of the project, we can have a look on

manufacturing procedure of sugar in the following paragraphs.

1.2 Sugarcane will be harvested at field and clean cane will be loaded in the

vehicles at field and brought to the factory. The gross weight shall be taken

and cane unloaded on the feeder table with the help of electric crane

unloader. The tare weight of the vehicle will be taken to arrive at the weight

of the cane.

1.3 Cane will be fed to cane carrier from the feeder table. The cane

preparatory devices viz. Kicker, chopper, Leveler, fibrizer etc., are

installed on the carrier for the preparation of cane. The prepared cane will

be taken to Mills by second carrier where juice is extracted using

compound imbibition process and hot water is applied for maximum

extraction before last mill. Mixed juice is strained and sent for processing.

Water for imbibition and mixed juice both are weighed in automatic

weighing scale & by mass flow meter respectively. Bagasse (residue of

cane after juice extraction) is used as fuel in the boiler and surplus

bagasse saved in the form of bales.

1.4 Mixed juice will be clarified by sulphitation process by heating at 700C in a

juice heater, phosphoric acid; sulphur dioxide gas & milk of Lime are used

as clarificants. These are thoroughly mixed in juice sulphiter. Then the

sulphited juice is heated to 1050C in another juice heater. This juice is

passed on to continuous clarifier through flash tank for settling. The settled

mud is filtered with the help of vacuum filter where filtrates are separated

and sent back to process. Hot condensate water is used to wash the cake

& recover maximum sugar from the cake. The washed filter cake with

minimum sugar content is sent out as bye product. Decanted clear juice

from clarifier is taken to Evaporators (multiple effects). The concentration is

increased to syrup consistency. The heat required for heating and

evaporation is used from exhaust steam and the bled vapors from

evaporators. Exhaust steam is obtained from prime mover turbine of power

generation.

1.5 The syrup from evaporators is sulphited to pH of 5.0 – 5.2 & it is used in

vacuum pan boiling to produce ‘A’ Massecuite. The necessary seed

crystals are taken in the pan and boiled with syrup / melt at about 600C.

This gives ‘A’ massecuite. ‘A’ Massecuite from the pan is discharged into

crystallizer. Then the sugar crystals are separated from the surrounding

film of mother liquor in centrifugal machine. It is also washed by

superheated water wash. The liquor is called as ‘A’ Heavy molasses and

the white crystal sugar is dropped on the hopper from centrifugal machine.

The sugar is conveyed on hoppers graded & bagged. The crystal sugar

gets dried & cooled while conveying on hoppers.

1.6 ‘A’ heavy molasses is subjected to second boiling to get ‘B’ Massecuite

there by B- sugar is used as Seed and / or excess is melted & melt is used

in ‘A’ boiling. B-Heavy molasses is subjected to third boiling to get C-

Massecuite and there by C- sugar and final molasses. C- Sugar is

magmized and double cured. The mother liquor separated is called C-Light

molasses. It is used in C boiling. C-double cured sugar is melted and melt

is used in A boiling.

UCL

Final molasses is weighed and stored in steel tanks (non duty paid). It is

then sold as bye product or used to distillery.

1.7 The sugar industry is the only industry blessed with captive regenerative

cellulosive matter to meet its own energy for processing sugar cane to

produce sugar. The optimal use of energy is the theme of the day. Cane

sugar industries having its own captive fuel till late were not very conscious

about the effective utilization of energy and to render surplus for other

utilization. In the present context newly developed technologies has proved

to be very effective in releasing energy (thermal & electrical) and

conservation of utilities.

1.8

The increasing concern about the effect of emissions from the power

industry, amongst others, on the environment is the driving force behind

the development of cogeneration and the utilization of renewable fuel

sources. The cane sugar industry is eminently suited, because it has been

in this field for 150 years or so as well as the fact that it uses a renewable

fuel that is C02 emission neutral.

1.9 Sugar factories, since inception are equipped with facilities for co-

generation of steam & power for captive use. However, in recent time the

meaning of the term “co-generation” has widened to denote the generation

of surplus power that can be supplied to the grid. The primary fuel in these

co-generation plants is bagasse, which is generated as a by-product of

cane crushing operations in the sugar manufacturing process. To extend

the operating days and to increase profitability, supplement fuel such as

coal can be used during off season.

1.10 India is one of the largest sugar producing nations in the world. There are

around 500 sugar factories in operation out of these two third are owned &

managed by cooperative sector & public sector. The estimated co-

generation potential from bagasse-based projects is 5000 MW, which

could be tapped by installing efficient co-generation plants.

UCL

1.11 Realizing the vast potential of cane production and power generation from

sugar plant co-generation a task force was constituted by Government of

India to address the constraints to commercially exploit the co-generation

potential. The task force had recommended the policy, fiscal incentives to

overcome constraints based on the recommendations Ministry of Non-

Conventional Renewable Energy Sources (MNRE) has announced

incentives like one time capital subsidy to set up co-generation projects in

the sugar factories.

2. USWL Background: 2.1 M/s. The Ugar Sugar Works Ltd. is one of the pioneers in sugar industry in

the state of Karnataka, having started its operations way back in 1939.

Proposed power export 50.20 MW 40.20 MW 45.20 MW

3.3

The raw material for manufacturing the above is Sugarcane i.e. 25 to 30

lakh MT which is sufficient for 120 to 150 days @ 20000 TCD. The

productivity of the sugar cane & yield depend on water supply & hence, the

cane can be grown in & around the Ugar. Which is on the bank of river

Krishna, has full & sufficient irrigation facility. It is expected that yield will

be 30 to 40 MT per Acre with recovery of sugar as 11% to 12%.

4. Co-generation scheme

4.1

The co-gen plant is configured keeping in view that the sugar factory

operations & also to meet peak steam & power requirement. The

installed capacity of co-gen plant is 77.6 MW with 4 numbers of boilers

having 310 TPH capacities @ 62 bar 490 deg C temp, one boiler having

100 TPH capacity @ 110 bar 540 deg Temp and one 50 TPH capacity @

32 bar 490 deg c & two back pressure TG sets of 22 MW each, one back

pressure TG of 12 MW and one extraction cum condensing turbo

alternator. of 20 MW

4.2 The total average cane crushing is envisaged 25 to 30 lakh MT every year

in the crushing period of 120 to 150 days with crushing rate of 20000 TPD

This would be achieved by the sugar factory from its past performance

data of unit I.

UCL

4.3 The process steam consumption is assumed 41.5% on cane; this could

be easily achieved as the proposed modification in the boiling house is

proved one. The electricity consumption during season of sugar factory,

cogeneration, colony etc. is taken as 28 kwh / MT of cane crushed with

electric drives for mill.

4.4 The proposal for expansion is to add one new boiler of 100 TPH capacity

along with modification in the existing boiler. The modification Scheme

envisages the boiler with super heater outlet steam parameters of 32 bar

& 490 Deg. C. & turbo-alternator with the steam inlet parameters of 30 bar

& 480 Deg. C. New Boiler is of 110 bar with 540 deg C steam parameters

with suitable new TG set. All the necessary auxiliary plants & systems in

respect of boiler modification will be installed for the efficient operations of

the co-gen plant.

4.5 The power generation is at 11 KV voltage level from the co-gen plant.

The interconnection with the KPTCL grid is at 110 KV after stepping up

the voltage from 11 KV to 110 KV. The power evacuation feeder is

connected to 110 KV sub-station at ugar which is around 2 Kms from the

co-gen plant site.

4.6 It is envisaged that the co-gen plant would run on sugar factory Bagasse

for 120 to 150 days (normal crushing season) & on saved bagasse for

around 150 to 200 days in non-crushing season to optimize the utilization

of co-gen plant.

4.7 Other equipments remains same, which comprises high pressure boiler,

CHAPTER 1

INTRODUCTION

A. INTRODUCTION ABOUT THE UGAR SUGAR WORKS 1. Background 1.1 The Ugar Sugar Works Ltd. is one of the pioneers in sugar production in the

state of Karnataka; the Company was incorporated on 11th September 1939,

under the able guidance and kind patronage of his late highness The

Rajasahab of Sangli with a crushing capacity of 500 tons per day.

1.2 Vaidya and Company was the first Managing Agents. In the year 1940, M/s.

Shirgaokar Brothers were called to manage the affairs of the Company and

they were the Managing Agents till 31st December 1969. M/s. Shirgaokar

Brothers who had by then made the Kolhapur Sugar Mills outstanding and

notable success proved to be successful in bringing up the Ugar Sugar

Works Ltd., also.

1.3 Under the overall supervision and control of M/s. Shirgaokar Brothers the

crushing capacity of the factory has been increased from time to time as

detailed in Table No. 1.1. At present the cane crushing capacity 12,000 TCD.

1.4 The company has introduced number of irrigation schemes for the

UCL

11

development of sugarcane in the area.

1.5 The company has started its own distillery during the year 1962-63 and liquor

section in the year 1967-68. New distillery plant unit with production capacity

of 45000 liters of rectified spirit has been commissioned in March 1995.

2. Cane availability 2.1 In Belgaum District where the plant is located, sugar cane is available from

the month of October to April even many times the season has to extend up

to the end of May. Typically, sugar cane availability is for a period of 7 to 8

months in a year. The registered area under sugar cane cultivation allocated

to Ugar Sugar Company is 60,000 acres. The important factor with regard to

the operation of USWL is that the cane arrival is fairly uniform and the plant

reaches the maximum crushing rate within a month of season

commencement. The total cane availability during a season is approximately

40 Lakh tones and most of it reaches the plant during the crushing season.

But now, due to new sugar plants installed in the nearby area, crushing

season days have reduced from 8 months to 5 to 6 months.

3. Steam Generation System

3.1 The main source of energy for the plant is bagasse and on an average the

bagasse generated is about 29% of the cane crushed. About 1 % of the

bagasse generated is utilized for juice filtration and the balance is available

for steam generation. While operating on a steady load the savings achieved

by the plant is about 2 to 3% on cane.

3.2 At present, the sugar plant supplies the entire steam requirement of the

distillery, which is around 10 to 15 tons per hour.

3.3 The existing steam generation system consists of 4 high pressure & 1 low

pressure water tube boilers and the details of these boilers are as given in

Table 1.2.

3.4 About 90% of the sugar plant's process steam requirement, which is at 2.5 kg

UCL

12

per cm2 abs., is met through exhaust of the backpressure turbines and the

balance requirement, which is at 9 kg per cm2, is met through extraction from

turbine.

4. Power Generation System 4.1 From the above steam, total power is generated through three turbines,

which meets the in-house requirement as well as exportable power to

KPTCL grid. The rating of which are as given in Table 1.3 and 4th Turbine

will be idle during season as it is condensing turbine.

* Siemens Turbine is old and fully condensing type which is modified to take extraction from HP to LP loop, hence it needs minimum 30 TPH steam in condensing.

4.2 During the crushing season for the present capacity all the 3 turbines and 4

Boilers are in operation.

4.3 The average own power generation is about 120.00 million units per year.

The major electrical load of the plant comprises boiler fans, feed pumps,

UCL

13

DC drives, cane cutter motors, centrifugals, injection water pumps and

cooling water pumps.

4.4 In addition to steam turbine generators, there are four diesel generators

available with USWL and the total capacity of the DG sets is 4600 KVA.

These DG sets are utilized as standby source of power during emergency

requirement and during start up operation as well as off-season operation.

5. Water and Condensate System

5.1 Only Exhaust steam condensate is recovered from the major process

equipment like Kestners and evaporators. The water from the above

recovery is utilized as feed water for the boilers. In addition, DM water is

available for feed water make up requirement.

6. Major Process Equipments

6.1 The plant follows standard three and half-massecute system for sugar

production.

6.2 The unit has got 2 milling tandems. The WIL mill having a size of 33" x 66"

is capable of crushing 4500 TCD and a second mill namely Shantaram

Machineries Pvt Ltd. having a size of 42" x 84" is capable of crushing 6500

TCD. The milling tandem along with the fibrizer is driven by DC drives.

6.3 The juice evaporation system comprises a quadruple effect evaporation

system. Earlier there was double effect semikesteners followed by

quadruple effect. In all, there were three numbers of SK1 bodies and two

numbers of SK2 bodies + 1 No. Robert’s Body in the pre-evaporators. The

quadruple effect evaporation system has three trains namely A, B & C and

two trains will be always on line. During last modification the above system

has been converted and made straight quad system.

6.4 The quadruple effect evaporation system has three trains namely A, B & C

and two trains will be always on line. The disposition of the heat transfer

surfaces for the streams is as given in Table 1.4

6.8 There are eight cell induced draught cooling towers for removing the heat

absorbed by the re-circulating water from the process.

7. Water supply system 7.1 The complete raw water requirement of the plant is drawn from river

Krishna, which is very near from the plant. The pumping station has got six

pumps out of which two pumps are utilized for sugar plant operation and the

pump ratings are as under:

Pump 1: Capacity: 390 M3/Hour. Head: 36.6 meters.

Pump 2: Capacity: 170 M3/Hour Head: 36.6 meters.

7.2 The raw water, from the river is brought to the plant by a 600-mm

underground RCC pipe and finally discharged into a constant level water

pond.

8. Boiler Feed Water System. 8.

The raw water is passed through the pre-water treatment plant comprises

solid contact clarifier and chemical dosing system. This clarified water is

passed through DM plants having the capacities of 30m3/hr, 60 and 72

m3/hr. (3 bed de-ionization plants). Exhaust condensate received from the

process and turbine condenser is used directly as Boiler feed water.

Softener water is being used as makeup water for power plant cooling tower

and drainage of this water is used as makeup water for sugar plant cooling

tower.

9. DISTILLERY 9.1 There are two distilleries available with the USWL. One is of very old with

the capacity of 30 KLPD and another one is of 45 KLPD. Total existing

capacity is 75 KLPD. Usw is having IML section also wherein bottling with

their own brand are being manufactured. There is a separate effluent

treatment plant ie evaporation and drying effluent to form a powder is

available with USW.

CHAPTER 2

NEED FOR THE PROJECT 1.0

1.1 All the nearby plants are going for the expansion and the forecast is total

crushing days will be reduced. Previously it was only one sugar factory in

Athani taluka, now there are 6 – 7 sugar factories in the radius of 20 to 30

KM. 1.2 Athani Farmers is going for expansion to 5000 TCD

Krishna SSK is going for expansion to 5000 TCD

Renuka Sugar – Kokatnur is going for expansion to 15000 TCD

Renuka Sugar Raibag SSK is going for expansion to 5000 TCD

Mohanrao Shinde Arag is 2500 TCD.

New plant Shirguppi sugar is coming up with capacity – 5000 TCD

New plant Shivshakti sugar is coming up with capacity 2500 TCD. 1.3 To achieve maximum crushing in minimum crop days with maximum sugar

recovery it is essential to go for expansion. Present overheads at Ugar are

already high, which leads to face difficulties in arriving at competitive cane

price. Hence Ugar Sugar management is proposing to expand the sugar

plant capacity to 20000 TCD.

2 Ugar Sugar has already taken steps to overcome the bottlenecks faced to

crush 416.66 TCH (10000 TCD in 24 hrs) and during last season USWL

has crushed almost 416.66 TCH. One of the bottlenecks is still exists i.e.at

cane unloading station of 42 x 84 mill. Due to space constraint and lower

capacity cane un-loaders they are unable to maintain uniform cane feeding.

Bagasse moisture will be on higher side, which leads to fluctuations in boiler

steam working parameters and in turn affects the crushing. Along with cane

unloading station the other parameters, i.e. reduction in crop days in future,

higher overheads per ton of cane and competitive cane price, sugar plant

expansion seems to be essential. Hence USWL proposing to expand the

crushing capacity.

UCL

18

2.1 Alongwith the expansion of the sugar plant capacity to 20000 TCD it is also

proposed to expand cogen power plant capacity to 76 MW with distillery of

200 KLPD capacity.

2.2 The main areas covered under the sugar plant expansion is mill and Boiling

house..

2.3 Mill Expansion: it is proposed to reshuffle the cane unloading system and

enhancing the unloader capacity from 7.5 MT to 12.5 MT to overcome the

existing cane feeding bottle necks and addition of Zero Mill of size 50” X

100” and last mill of 50 X 100 with GRPF for existing 42 X 84 mill to crush

at the required capacity.

2.4 Boiling House capacity to be increased to 20000 TCD, for new additions

capacity shall be suitable for 909 TCH. One parallel boiling house set has

been proposed for the expansion. 2.5 The viability of the sugar factory is improved due to cogeneration, which is

also a need of the State to have more power to meet the growing power

demand in the State. 2.6 Alcohol plays one of the important role in the countries economy. Alcohol is

by product of sugar industry, which is linked to agriculture. There alcohol

produced from molasses deserves the preferential place as a substitute

feed stock for chemical industry and to bridge a gap in our every need. The

gap between the availability of alcohol and requirement by the industry has

been avoiding.

CHAPTER 3

PRODUCT SALE POLICY 1.0 Sugar Sale Policy

A) Sugar sales are governed by sugar control order of Central Government

& the releases are given to the Sugar Factory in proportion to their

production / stock of season with the factory. Factory will follow these

rules for sugar sale & abide by the rules. Sugar is sold to Government

nominees & or wholesale dealers registered with the Government.

2.0 Molasses Sale Policy A) Molasses sales are governed by State Excise. Factory will possess M1

license issued by the Commissioner of State Excise, which will permit to

produce the molasses, hold in stock & sell molasses to authorized

parties. Factory will find the parties i.e. Distilleries, Cattle Feed producer

or otherwise exporter of molasses who can purchase the molasses at

remunerative price. This will be followed till such time as own distillery

is established.

3.0 Filter Cake Sale Policy (Press Mud) A) Filter cake is produced as a by-product at the rotary vacuum filter where

the muddy juice is filtered. This filter cake is rich in minerals, potash as

also the phosphate, sulphites & organic matter which means rich

manure. Hence, this is most suitable for soils. The factory will adopt the

policy to return the rich manure to soil by selling the filter cake

particularly to cane growers who have supplied the cane to factory. It is

general experience that cane growers are very much interested to

purchase filter cake at a nominal price fixed by the factory.

TECHNO COMMERCIAL ASPECTS

1 Description of operating Scheme: a) The plant operating scheme envisages both mill tandems of Dia 33” X

66” and 42” X 84” will operate at 6000 & 14000 TCD respectively to

the total capacity of 20000 TCD. Boiling house is also being expanded

to take additional load of expanded capacity.

b) 33’’X 66’’ mill with minor modifications will crush 6000 TCD as per the

existing past data. It is proposed to modify and enhance the capacity

of 42 X 84 Mill to 14000 TCD by adding zero mill of 50’’ X 100’’ and

last mill also 50” X 100” along-with the modifications in the cane

unloaders, cane preparatory devices and existing mills.

c) Juice heaters will be added to balance the mass and temperature i.e.

wide gap plate type heat exchanger is proposed to operate on vapour

condensate. Existing juice heaters will be modified to suit the

expanded capacity.

d) Juice sulphiter and syrup sulphiter are proposed to be added suitably

to handle the total juice flow for the expanded capacity

e) It is proposed to add juice clarifier to maintain the required retention

time for juice clarification.

f) Plate type juice heaters are also proposed in addition to the existing to

operate on 1st body vapours

g) It is proposed to add evaporator body for 1st and 2nd effect in the

existing set up, for Heat & mass balance. There will be total 3 streams,

two operating and one set will be cleaning so that every 10 to 15 days

clean set will be online.

h) In addition to the existing Batch type A pans and continuous pan it is

proposed to add one more continuous pan for A massecuite boiling. It

is proposed to add continuous horizontal pans for B and C massecuite

handling.

UCL

23

2 nos batch type A centrifugal machines are prposed for the expanded

capacity

Four numbers of continuous centrifugal machines are proposed for B

and C massecuite for the expanded capacity

Modification is proposed in the sugar drying and sugar hoppers. There

is no change in sugar silo system

One additional sugar bagging and conveying system up to sugar go-

down is proposed

One additional cooling tower is proposed to take additional heat load

generated by condensers

For cogeneration 1 new Boiler of 100 TPH with working parameters of

110 ata and 540 deg C temperature. Alongwith new Boiler one old

Boiler of 32 bar 380 deg temp is proposed modify to get outlet

temperature 490 deg C.

For above Boiler Two TG sets have been proposed, 1 no 12 MW back

pressure TG set suitable for 32 bar steam and one 20 MW double

extraction cum condensing TG set suitable for new Boiler steam.

Switch yard with transmission line is also to be expanded suitably.

Existing Distillery capacity is 75 KLPD, additional 125 KLPD distillery

to be added.

b) Bagasse saving for 135 days operation with 909 TCH increased

crushing & 90 PLF nearly 137696 MT of bagasse can be saved. Total

Bagasse saving in a season for 909 TCH will be about 137696 MT

c) During season as well as off season USW needs steam to distillery 25

TPH and for evaporator drier of ETP about 25 TPH. This requirement

will be fulfilled by operating cogeneration during season & off season.

d) When cogeneration is in operation distillery steam requirement can be

met through the turbine extraction. Hence it is essential to operate

cogeneration during off season with saved bagasse.

e) Accordingly during off season one of the Boilers will be operated on

saved bagasse for maximum possible days.

UCL

24

2 Operation of the Plant During Crushing Season: a) 310 TPH Steam will be generated from 4 nos Boiler at 62 bar and 55

TPH from modified Boiler at 32 bar, 490 deg C temperature, 100 TPH

steam will be generated from new Boiler of 100 TPH capacity.

The entire steam generated in the boiler is fed to four turbines. 260

TPH for SNM Turbine, 92.50 TPH for DEC Turbine and 80 TPH to

new Back pressure Turbine. The uncontrolled extraction from the

turbine at 9 ata gives 37.5 TPH of steam approximately at a

temperature of 270 Deg. C. The controlled extraction from the turbine

at 2.5 ata provides 380.06 TPH of steam approximately at 140 Deg. C.

b) A quantity of 30 TPH of steam, being the difference between the

generation and input to SNM Turbines at 62 bar will be mixed with 32

bar 50 TPH steam from modified Boiler through PRV to get 80 TPH.

c) With the above given steam input & extractions from the turbine, the

co gen TG generates 72890 KW, at the generator terminals. Part of

the generated power is used for meeting power requirement of the

auxiliaries of the co gen plant & the power requirement of the sugar

factory.

d) Only the exhaust steam condensate from the sugar factory process &

the condensate from turbine surface condenser are being used as the

feed water for the boilers. The cycle make up water for the operation

of co gen plant will be DM water.

Now the Government of Karnataka has granted for state excise 200 KLPD capacity Distillery. In order to run the distillery through the year, the factory shall get an allotment of about 96000 to 1,20,000 Tones of Molasses is available from their own sugar plant. Balance requirement of about 100000 MT of molasses has to be procured from the market. If therefore the Distillery shall have a daily capacity 200000 liters of Rectified spirit by adopting proven technology of continuous fermentation the factory can have higher productivity. In order to operate the distillery throughout the year say about 300 days/ annum, it is proposed that the Distillery shall have separate boiler in off season of suitable capacity with T.G. set. They shall have its own arrangement for steam & electricity. The Power generated will full for operating the distillery as well as for lightening the roads & buildings. Distillery will discharge spent wash effluent at the rate of 10 to 12 liters per liter of Alcohol produced. Daily production of spent wash shall be 2000 m3 to 2400 m3. The spent wash has high B.O.D. to the extent of 80,000 to 90,000 mg/l. As per the standard laid down by the Government the BOD should be brought down to 100 to 30 mg /l. Before it is charged over land or water respectively. There is no suitable and economical method to achieve these standards. The method of concentration and drying of spent wash besides being very costly, pose number of problems, as regards it maintenance and repairs due to high temperature and corrosive nature of spent wash. The alcohol produced in the distillery shall be sold as per the Government’s directives to the parties getting allotment. The distillery shall make good profits, besides getting better price for its molasses. It provides good opportunity for the further diversification. The distillery project is very attractive as the demand for alcohol will be increasing for manufacturing chemicals. During distillation of Rectified Spirit by product known as fusel oil is produced to the extent of 0.2 to 0.3 per cent of the total alcohol produced. Fusel oil is a mixture of higher alcohol such as propyl alcohol, butyl alcohol and amyl alcohol. Amyl alcohol content ranges from 50 to 60 per cent in fusel oil. Spent wash discharged from distillation column is a valuable by-product if it is used properly. If neglected, it becomes hazardous causing pollution of environment. It is rich in nutrients, for use in fertilizers. It is also capable of generating energy. In anaerobic digestion of spent wash, methane gas is

produced which can be used as a fuel in boiler. The quantity of gas produced is almost sufficient to generate the steam required for generation. It requires secondary treatment for the Distilleries are as under:

1. Rectified Spirit Grade 1 2. Impure Spirit Grade 2 3. Fusel Oil 4. Methane Gas 5. CO2 6. Yeast sludge 7. Ethanol 98.6 8. E.N.A.( Extra neutral alcohol)

e) Pan B shall be located on south side of the existing Pan B.

f) Two Centrifugal machines to be located in the series of existing battery

and two machines near melter on east side of the battery.

g) Sugar grader to be located adjacent to the existing grader.

h) Boiler to be located near 50 TPH Boiler south side of the WIL boiler

i) Turbine to be located adjacent to the existing turbine

j) Distillery unit to be located adjacent to the existing distillery

k) Effluent treatment plant to be located in the existing ETP area, adequate

space is available.

3) Inter Connection Aspects: The area identified for the expansion is inside the existing sugar complex.

Hence there will be little obstruction for the material shifting. But it can be

managed.

4) The nearest railway station Ugar khurd 2 KM from the sugar factory. The

state highway connecting sankeshwar to Bijapur is near to the sugar factory.

National Highway No 4 is 70 KM from the factory site. The plant is therefore

well connected by road facilities for the transportation of equipments.

5) Water Availability: The raw water for the sugar plant is required for meeting the following

requirements.

a) Make up water to the steam generator.

b) Make up water to the cooling tower.

c) Ash disposal

d) Other plant services

The estimated additional quantity of raw water requirement for the expanded

capacity given in the enclosed sheet. The sugar plant presently draws water

from River Krishna which has adequate water flow. It is therefore envisaged

that the sugar plant water requirement will be met from the same facility.

6) Availability of Fuel:

UCL

59

a) The project is based on the in house generation of bagasse from the

sugar factory. Plenty of bagasse will be surplus after meeting own

requirement during season.

c) Surplus Bagasse will be stored in the available area. And same can be

used during off season for co-generation.

7) Interconnection with Grid: Grid interconnection facility is already available with the factory, expansion of

the unit can be accommodated adjacent to the site.

8) Ecological Impact: a) All the necessary measures are planned to be taken in the plant design

for minimizing the impact on the ecology of the environment. All those

equipment required for ensuring a safe atmosphere will be provided for

the project & located within the sugar complex premises.

d) The detrimental effect of SO2 & Nos will be partially mitigated by a

green belt along the boundary of the plant generally in line with

Karnataka State Pollution Control Board requirement. The plantation

will also help in oxygen replenishment.

c) The particulate emission from the co-gen plant shall be controlled to

less than 150 mg/Nm3 by the use of high efficiency ESP/ wet scrubber.

d) There will be little thermal pollution of water as a closed cycle concept

has been proposed for the sugar plant. The condenser will be designed

with temperature rise limited to 10 Deg. C. above cooling water entering

the condenser. The hot water will be cooled through induced draft

cooling tower & cooling tower blow down will be discharged into the

nearest drain.

UCL

60

e) There will, however, be some contribution to thermal pollution of the

atmosphere by the discharge of hot flue gases. The effect at ground

level will be minimal, as the heat will be dissipated into higher layers of

the atmosphere.

f) Liquid wastes from the milling plant and boiling house, This water will

be diluted and discharged into circulating water pit after checking for

dissolved solids and pit.

CHAPTER 7 RISK ANALYSIS & MANAGEMENT

1) USWL Performance:

a) Risk of Performance for next 15 years. i) The Ugar Sugar Works Ltd., has achieved excellent performance,

Hence there is no risk of performance

b) Management Stability / Political Environment i) The management of the USWL has been steady in the past. It has

been working as one united team.

ii) USWL has a vast pool of technically qualified staff, which has

gained ample training & experience. Steady management control

mitigates the risks of management instability.

iii) State support for the sugar industry as a whole mitigates the risk of

unfavorable political environment.

2) Cane Availability Risk: a) Availability of water for cane production

i) The risk of non-availability of water for cane production is mitigated,

as sufficient amount of water is available from River Krishna as well

as irrigation on wells & also Lift Irrigation Schemes (LIS) by sugar

factory as well as irrigation pumps of individual cultivators.

UCL

62

iii) Average Rainfall is 600 mm from June to September. The river

Krishna is flowing at 1 km distance from factory. As a result of

availability of water from River, tank & borewell the sugarcane

production is expected to increase.

iv) Risk regarding effects of deregulation & exposure to international

market is mitigated as the sugar factory has already started cutting

costs to remain price competitive by increasing the crushing

capacity & optimizing capacity utilization.

b) Cane Development in the area

i) Significant potential exists for cane development in the area.

ii) Area of operation consists large no. of villages from athani, taluka,

on river bank Krishna. At present cane area is covered by river

irrigation & as well as well irrigation.

iii) Well irrigation area is also benefited by percolation of irrigation

tanks. The cane area is also expected to increase due to addition

of new irrigation schemes.

iv) In addition, the sugar factory has a separate agricultural department

headed by qualified Cane Manager (CM). The agricultural

department takes complete responsibility of the command area for

development of cane.

c) Risks of farmers shifting to cash crops other than cane

i) Farmers are not likely to shift to other cash crops as the sugar

factory offers an assured market for cane & take complete

responsibility of command area whereas other cash crops are

market driven & there is no assured take off.

UCL

63

ii) The relative profitability per hectare of different crops in India as per

the draft report of World Bank is the highest for sugar cane.

3) Fuel Risk: a) Risk of non-availability of bagasse will not arise as bagasse generated

from the own mill will be more than sufficient.

4) Technology Risk: Technology adopted for the expansion plant is an established technology & in

operation in the same plant for the past 75 years.

5) Construction Time: i) Total expansion work requires hardly 6 to 7 months. Hence there is no

risk of work completion before start of the coming crushing season.

6) Environment Risks: i) The compliance with the Indian environmental standards will be ensured

from the time of project design. It is proposed that factory will undertake

rapid Environmental Impact Assessment (EIA) & Disaster Management

Plan through a reputed agency.

ii) Further during the construction phase an environment management plan

will be designed & will be monitored by the management of factory.

7) Performance of Sugar Plant: i) Performance risk of sugar plant is mitigated by installing established

technology.

ii) Procuring the plant & machinery from proven & established equipment

manufacturers.

UCL

64

iii) Engaging experienced staff for the operation & maintenance of the

cogen plant.

8) Cost Overrun risk: i) The actual costs are expected to fall within the estimated range.

ii) The estimated project cost conservatively on the basis of quotes

available from the various suppliers & contractors.

iii) Individual components of the project will be executed under EPC with

fixed price EPC contract thereby minimizing the risk of cost overrun.

iv) The total project cost includes significant amount of contingency

premium, which is sufficient to meet the cost associated with any

foreseen delays, change orders & other unforeseen events.

9) Risk of Non Payment by product purchaser: i) Obtaining two months revolving letter of Credit (LOC) could mitigate risk

relating to buyer’s payment capacity & willingness to pay backed by

functional escrow account.

10) Operational Risks: i) The technology of operation of sugar plant is not a new; there will not be

any problem of operation as trained manpower is available with the

plant.

ii) Conservation cost projections mitigates the risk of sharp increase in

operating costs. USWL rely on the technical, operating & management

expertise of the equipment supplier & is confident of meeting the

operating cost target. Even in the unlikely event of operating cost

increase, the impact on the project returns is not significant.

UCL

65

11) Price & Margin Risks: As factory is already entered into EPA with power trading agency /KPTCL as

per the Energy Purchase Policy of KPTCL taking into account adequate

returns to investment the price & margin risk is taken care off.

12) Risk Management - Insurance: a) Pre – Completion

The company is expected to take a seamless comprehensive project

insurance package covering all construction risks from effective date of

construction contract until completion.

b) Post completion

From the date of physical completion of the plant the company is

expected to maintain a package of operational insurance consisting of:

i) Fire policy & other perils (like earthquake, flood, storm, lightening

etc.) covering physical loss or damage to the plant including

ancillaries.

ii) Loss of profits on account of business interruption due to fire,

machinery breakdown & related perils.

iii) Third party liability, covering all legal & contractual liability arising

out of maintenance & operations of plant on occurrence basis.

iv) Theft policy covering burglary, house breaking instances of plant on

occurrence basis.

c) Indian legislation requires that all insurance relating to activities

undertaken in India be affected within the territory. The insurance

market is influenced by major international reinsurance supports

particularly for large projects. Indian insurance companies have the

practice of seeking reinsurance from International Insurers to the extent

of & upwards of 90% in some cases.

d) With the recent opening up of the insurance section to the private sector

it is expected that the company will benefit from the increased

competition as new insurance companies will offer policies, which will be

specific to users requirement. Policies may be offered to cover fuel risks

& other risks specific to the power section.
