OPW TOTAL VAPOUR SOLUTION™

Stops Excess Vapour Emissions To Protect The Environment

Provides For Cleaner Air

Saves Fueling Operators Money By Preventing Vapour Loss

Improves Profitability By Converting Vapour To Saleable Fuel

Provides Fast Payback (ROI)

The World’s Most Innovative And

Effective Vapour Solution

4

OPW TOTAL VAPOUR SOLUTION™

Controls The Creation Of Vapour Over The Duration Of The Delivery And Within The Storage Tanks On A Continuous Basis

Keeps The Product In A Liquid State During The Delivery To Prevent An Increase Of Vapour Creation (Where The Largest Losses Occur)

Manages The Vapour Collected From Nozzles On Stage 2 Systems

5

OPW TOTAL VAPOUR SOLUTION™

Tankers Are Designed To Draw The Vapour Back From The Site Using The Vacuum Created By The Off-Loading Procedure

This Is Done When Off-Loading Both Spirit & Diesel And Controlled At 32mbar

6

OPW TOTAL VAPOUR SOLUTION™

There Are Four (4) Main Components

Each Component Is An Integral Part In The Total Processing Of Stage 1B And Stage 2 Vapour And Vapour Produced By Natural Venting

OPW TOTAL VAPOUR SOLUTION™

Historical Results For Wet Stock Losses For A Standard Site Have

Shown That Expected Losses Could Be Between 0.25 To 0.35%

Of Sales Volume.

For Example, For A Site Selling 16,000,000 Liters Of Spirit And

Taking An Average Loss Of 0.30% This Would Equate To:

16,000,000 x 0.30/100= 48,000 Liters Per Year!!

• Using Data From A Test Site Which Has Been Operating For Over 6

Months The Results Have Shown A Reduction In Wet Stock

Management Company.

• Therefore A Site Selling 16,000,000 Million Liters Of Spirit Would

Show A Loss Of 16,000,000 x 0.045/100= 7,200 Liters Per Annum.

This Would Show An Average Annual Saving In The Region

Of 40,800 Liters!!!

Electrostatic Hazards Of Plastic Pipework For Service Stations

14

Maddington Service Station, Perth, Western Australia

15

• At the filling station there will always be a risk of a flammable atmosphere

• ALL ignition sources must be eliminated

Flammable vapors

16

17

Fuel flow creates charge separation in the pipe

The charges cannot go anywhere (non-conductive materials cannot be earthed) and accumulate

Static electricity generation in pipe

18

Static charges create an electrostatic field

Conductors within the field get an induced charge

Electrostatic induction

19

Possible discharges

Between areas on the pipe wall with different charges.

Between negatively charged pipe and positively charged fuel.

Between negatively charged pipe and grounded conductor.

20

Discharge In Chamber

21

• Use of non-conductive fuel piping system

• High speed fuel flow

• Low conductivity fuels

• Fuel quality, impurities in the fuel

• Dry air

• Turbulence: Elbows, reducers, filters or flame arresters

• Vapor traps (underground fill boxes, chambers)

Factors that influence the rate of static fires

22

Avoid non-conductive fuel piping system

( End to End continuity )

All major recommendations for hazardous areas strongly discourage the use of non grounded systems: Cenelec TR 50404

IEC TR60079-32

NFPA 30, 30A and 77

IP Guidelines Part 21

EN 14125, EN 13463-1

AS NZS 1020-1995

National Standards

Standards documents

23

If you decide to use non-conductive fuel piping system despite the risks, follow the the IEC standard TR60079-32 and/or EN14125 / EN13463-1: Take necessary precuations

If non-conductive fuel piping system is used..

Unburied pipes are charged more so burial of the pipe is crucial

Backfill on top of the pipes before starting any fuel flow

Keep pipe lengths inside chambers as short as possible

24

Charging increases with flow velocity

Fuel flow must be maximum 2,8 m/s

Limit speed of fuel flow

Max 2,8 m/s

25

All isolated conductive objects, such as flanges, jubilee clips, in chambers and fill boxes must be bonded and grounded

Bonding and grounding

26

Limit fuel flow to max 2,8 m/s

Do not use flame arresters or filters until after careful consideration

Mount safety vales on all fill necks

Bond and ground all isolated conductive objects in chambers and fill boxes

Cap welding socket wiring

Check earthing arrangements after all work in chambers and fill boxes

Check earthing arrangements periodically 1 time/year

The list of precautions can be found in the standards mentioned.

*The precautions cannot guarantee that no fire will occur

Summary of precautions* for non-conductive system

Nozzle with no continuity (Isolated)

Fire at the filling station must be prevented
