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

7

OPW TOTAL VAPOUR SOLUTION™

• Converts Vapour Back Into

Liquid-Returns Liquid Back To Underground Tank As Saleable Fuel

• Maintains Tank Pressure To

Eliminate Vapour Emissions

OPW TOTAL VAPOUR SOLUTION™

• Reduces Vapour Pressures In

Tanks By Spreading Delivery Across The Floor Of The Tank

• Keeps The Surface And

Product Calm During Deliveries To Eliminate Vapour Generation

OPW TOTAL VAPOUR SOLUTION™

• Self Generating . No Power

Required.

• Offsets The Vacuum Created

By Tanker

• Introduces The Vapour Back

Into The Liquid Flow During Delivery (Wetting The Vapours)

OPW TOTAL VAPOUR SOLUTION™

• Prevents Vapours From

Returning To Tanker

• Retains Vapour In UST So It

Can Be Processed Back Into Liquid

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!!!

Remember This Benefit:

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
• bjects, 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
