Approach…

PURIFYING CHIMNEY EXHAUST SO AS TO

REDUCE AIR POLLUTION AND CONSEQUENT GLOBAL WARMING

OUR IDEA…OUR APPROACH…

• POLLUTION AND GLOBAL WARMING

EXHAUST FROM CHIMNEYS

•REDUCTION IN AIR POLLUTION & RELATED CONCERNS

REDUCTION IN THE QUANTITY OF EXHAUST

COMPONENTS OF CHIMNEY EXHAUST :

PERCENTAGE OF SPECIFIC TOXINS IN AN AVERAGE CHIMNEY EXHAUST

CO & CO2SO2NO & NO2WATER VAPOURDUST PARTICLESOTHERS

THE APPARATUS :

Filtering Chamber 1

Filtering chamber 2

Filtering chamber 3

FILTERING CHAMBER 1(FC1)

FILTERING CHAMBER 2(FC2)

Layout : FC2 comprises of chemical solutions and reagents aligned in

a proper manner. It has 3 sections so as to absorb much of the harmful gases.

DESCRIPTION :

SO2 + NaOH ---- Na2SO4 + H20

SECTION 1 :

CO2 + Ca(OH)2 ---- CaCO3 + H2O

SECTION 2 :

2NO2 + 3H2 ----2NH3 + H2O

SECTION 3:

FILTERING CHAMBER 3(FC3)

Exhaust’s temperature is reduced.

Dust and soot is filtered

Toxic gases treated.

OVERALL IMPACT :

EFFECTIVENESS AND PRECISION

Is economical, efficient and stable.

Works silently without interrupting the normal running of the chimney.

Easily installed adjacent to an existing chimney with few structural changes.

REAL LIFE APPLICATION

BOKARO STEEL LIMITED(B.S.L)

Type : State Owned Enterprise Traded as : NSE : SAILIndustry : Iron and SteelFounded : 1964Annual Turnover: 50,348 crores (2011-12) B.S.L houses 5 blast furnaces with total capacity to produce 4.5

million tonnes of liquid steel per year. The plant is undergoing mass modernization after which the

output is expected to be 10 MT of steel per annum.

BOKARO STEEL PLANT
