With certain well as installation and maintenance requirements. In addition, this document also defines the process upgrades TVS can be also fitted on petrol stations with Stage 1. The technology can be customized to the of ordering: starting from inquiry, through technical assessment of the chosen petrol station to the petrol station, but some of the benefits for easier installation would be that vent lines are connected in a installation and starting up of the OPW TVS. manifold above ground (or manifold is easily accessible), there is a 3-phase electricity available and there is physical space next to the fill lines on the station for the location of Vapor Management Panel. About OPW TVS The OPW Total Vapour Solution™ (OPW TVS) is designed to maintain the vapour pressure in the Maintenance and Support underground storage tanks at specific pre-determined pressure settings, as well as to process gasoline OPW TVS has an expected life of 15 years, while key components on the vaporsaver unit also have a long vapours back into liquid, returning it to the underground tanks (UST) as resalable fuel. OPW TVS is life (compressor – 10 years; membrane – 9 years). Certain standard maintenance of the vaporsaver (once designed to be installed on petrol stations with Stage 2, or with some upgrades on sites with Stage 1 per year) is needed for checkups of wearable components (belts, gaskets, sealing). Vapor Management alone. Panel, Soft Fill and Accumulus valve are mechanical solutions with no maintenance needed. OPW Fueling Components EMEA (Europe, Middle East and Africa) has an extensive network of distributors in over 75 countries that will support the servicing, maintenance, warranty and any other customer defined issue How it works related to OPW TVS. In addition, OPW keeps close contacts to its end-users and is always available for any assistance with regard to TVS. OPW TVS is comprised of 4 elements: OPW Vaporsaver (converting vapours back into gasoline), Soft fill (reducing vapours during fuel truck delivery), Accumulus valve (returning vapour to liquid flow during delivery through vacuum) and Vapour Management Panel (prevents vapour from going back to the tanker). After keeping more vapour in the ullage space, and reducing the creation of vapour OPW TVS Certifications and Listings: during delivery, vaporsaver turns on at a specific pressure level reached in the tank (+0.37 mBar) and ATEX Listing SIRA 03ATEX 9535 starts processing the vapours (air and hydrocarbon mixture) with membrane technology, by separating TUV Certification 97-11.1 hydrocarbon from air and cooling it to the liquid state creating petrol and super saturated vapour that goes back into the tank.

  5. 5. 8 | page 9 | page OPW Total Vapour Solution Softfill System OPW TVS is the most effective way available today to prevent vapour venting into the atmosphere. On the forecourt, vapour is generated through tank pressurization and natural venting, during quiet traffic periods. Further vapour is produced during the delivery process as the tanker drops fuel into the underground tank. Finally, on sites with Stage 2 systems, the vapour being recovered by the vacuum pumps from the vehicles is returned to the underground tank. In a typical vapour recovery application, during the fill process, vapour would be recovered by the delivery tanker because of a vacuum created in the tanker as the liquid is being delivered. Often overlooked, it is important to understand that even when the delivery tanker is delivering diesel, the tanker is connected to the vapour recovery system and therefore vapour is drawn from the site’s tanks. OPW Total Vapour Solution™ (TVS): • Controls the creation of vapour over the duration of the delivery and within the storage tank on a continuous basis • Keeps the product in a liquid state during a product drop to prevent vapour creation where the largest losses occur • Manages the vapour collected from nozzles on Stage 2 systems • Maintains storage tanks in negative pressure by automatically converting excess vapours back into saleable fuel, further preventing vapour loss There are 4 main components of the Petroman Total Processing, each playing an integral part in the total processing of the stages 1B and stage 2 vapour, as well as the natural venting of the product. On the forecourt vapour is generated through natural venting during the quieter period, further vapour is produced during the delivery process by the effect of the liquid passing into the tank and on sites with Stage 2 systems the vapour being recovered from the pumps is returned to the underground tank. The delivery process causes turbulence in the tanks through the liquid passing down the drop tube On a normal site this vapour would be recovered by the delivery tanker during the fill process by virtue and exiting through the orifice directly into the tank. In order to control the delivery of the liquid the first of the vacuum created in the tanker as the liquid is delivered. It is not always understood that even component used is the Softfill system. when the delivery tanker is delivering diesel the tanker is connected to the vapour recovery system and This is basically a beam which is attached to the bottom of the drop tube and this allows the liquid to therefore vapour is drawn from the sites tanks. feed along the base of the tank and is delivered through a large number of small holes (having a total TVS is designed to maintain the vapour, produced by these various processes, underground in the sites surface area much greater than the normal 4” orifice). The effect of this is to calm the delivery and thus tank farm and then to process the vapour back to liquid which is returned to the underground tanks reduce the vapour generation caused by the delivery. (UST). The effect of this system is to reduce the wet stock losses normally associated with deliveries and The secondary action of the Softfill is to introduce the vapour mixture being returned into the liquid flow provide the vapour as a saleable product. by the Accumulus valve, back into the product within the tank in a controlled manner to aid the vapour introduction back into the liquid. There are 4 main components of the system, each playing an integral part in the total processing of This is retrofitted through the existing 4” tee on top of the tank and can be easily removed for Stages 1B and 2 vapour and vapour produced by natural venting, which are: maintenance. 1.

  6. 6. 10 | p a g e 11 | p a g e Accumulus valve Vapour Management Panel During the delivery the vapour generation occurs within the spirit tanks and this passes from tank to tank through the vapour recovery manifold. The vapour air mixture that is generated is rich in hydrocarbons and the Accumulus valves works to reduce the pressure in the tank and to introduce the vapour back into the liquid flow, causing the hydrocarbon On a normal delivery the delivery tanker would connect up to the vapour recovery point when offloading component of the mixture to be entrained back into the liquid. diesel and petrol. The effect of the tanker is to pull the vapour from the underground tanks, back into the tanker. Even when diesel is being offloaded, with the vapour recovery hose connected, the tanker pulls The valve itself is positioned at the top of the drop tube, in the tank, in the vapour space. The valve forms the petrol vapour from the UST. The effect of this is a loss in vapour that can equate to 20 – 30 liters of part of the drop tube and is positioned below the overfill prevention valve. fuel per delivery. The design of the valve utilises the liquid flow to create a vacuum, this is done by passing the liquid The vapour management panel is positioned on the vapour recovery manifold between the UST and the being delivered to the tank through a venturi which creates a vacuum at the centre. This area of vacuum vapour recover hook up point. The panel contains two sets of valves, the primary valves are for vapour is linked to the vapour space in the tank by a tube and this vacuum pulls the vapour air mixture being management and these valves are inserted into the panel and control the vapour allowed from the UST generated back into the liquid flow from the tanker, thus entraining the hydrocarbons back into the to the tanker. liquid. The valves are weighted to lift when the pressure in the UST reach 34 mbar, the effect of these valves is The effect of this is to reduce the generated pressure during the delivery. to prevent vapour from returning to the tanker when diesel is being offloaded. The valves will remain closed during this process and the tanker will pull air into the tanker through its own vent system. Once the delivery of spirit is started the pressure will start to build up in the UST, but to a lesser extent than on a normal site because of the above components, as the pressure increases this is held back by the valves and the processing unit start to work (this is explained below). The valves will not lift until a pressure of 34mbar is reached and with the other components operating this pressure may not be reached at all throughout the delivery process, thus meaning no return of vapour to the delivery tanker. Once the tanker has finished its delivery, the valves close and trap the vapour in the UST, this vapour is then processed back to liquid. The secondary valves in the panel are the PV valves which are normally positioned at the top of the vent stack. These have been brought down to low level for ease of maintenance and weather caps put onto the vent stacks. The benefit of the vapour management panel is to reduce or eliminate the vapour going back to the tanker and to trap the vapour in the UST, so that it can be processed back to liquid.

  7. 7. 12 | p a g e 13 | p a g e OPW Vaporsaver Operation of vaporsaver in several simple steps: As pressure in the storage tank rises, the pressure sensor monitoring the tanks will start the System. 1. The feed pump draws the vapour/air (saturated vapour) mixture from the storage tank. 2. The vapour/air flow is pressurised. 3. Increasing pressure within the same volume causes the vapour stream temperature to rise. 4. The heated vapour stream passes through a cooler. 5. The cooler reduces the vapour stream to ambient temperature. 6. The cooling process causes liquid gasoline to condense. 7. The vapour/air mixture and liquid gasoline go to a separator. 8. The liquid gasoline is separated, removed from the vapour/air mixture, and stored for later removal and return to the storage tank. 9. The remaining vapour/air flow proceeds to the membrane. 10. The membrane material has two sides, a pressure (feed) side, and a vacuum (permeate) side. 11. As hydrocarbon molecules pass along the membrane pressure side, they are attracted and bond to the membrane material. 12. Air molecules are repelled by the membrane surface on the pressure side, and continue on until released from the Control System as clean air (residue). 13. The pressure differential between the pressure side and the vacuum side cause the hydrocarbon molecules to be drawn through the membrane material. As explained above the effect of the vapour management panel is to retain the vapour in the UST. In addition to this, vapour is returned to the tanks by the Stage 2 system on the pumps and also through 14. The vacuum pump returns the supersaturated gasoline vapour (permeate) to the storage tank natural venting during quieter times on the forecourt. where some of it will condense into liquid gasoline. The OPW processing unit is provided to process the vapour back to liquid and thus a saleable product. 15.

The air mixture is passed through the membrane. The membrane allows the hydrocarbon element to pass membrane allows the hydrocarbon molecules to readily pass through while the air (oxygen and nitrogen) through but prevents the air from exiting. molecules are less permeable and are vented to the atmosphere. This effect allows the air to be split from the hydrocarbon; the air which is clean can then be passed out to atmosphere through a vent system. The hydrocarbon element is pumped back into the UST and this liquid stream is run through an inner pipe contained within one of the existing vent lines. This allows the The Overall Effect of OPW TVS liquid to be returned directly to the tank.

Each of the components compliments each other in reducing the pressure, maintaining the vapour in the UST and processing this vapour back to liquid.
