2 About Carbovac Why Emission Control? CARBOVAC is a worldwide supplier of hydrocarbon vapour recovery solutions for truck, rail car, marine and storage tank loading applications. Our engineering team was the first to use innovative activated carbon & dry screw vacuum pump technology in our hydrocarbon vapour recovery unit systems throughout the industry. Our Vapour Recovery Units are provided with a reliable process management system ensuring a high safety & availability rate with lowest energy consumption and higher carbon lifetime expectancy. Volatile Organic Compounds (VOC) emissions resulting from the storage of petrol and its distribution from terminals to service stations, have a very negative impact on the environment: Human health (drivers, operator, environment) Pollution of the troposphere (ozone creation at ground level) Safety on the terminal (flammable vapours, explosion risks) That is why such VOC emissions have to be controlled. Our vapour recovery units meet worldwide legal requirement and vapour emission legislations, such as: EPA - Clean Air Act (USA) European Parliament and Council Directive 94/63/EC of 20 December 1994 TA-Luft 01 in Germany, LRV in Switzerland, NER in Netherland, etc. Our extensive know-how & experience on the VRU process using dry screw vacuum pumps (to regenerate the activated carbon), is recognized for its simplicity and reliability by many global oil & gas and storage companies on the market. More than 5 registered patents CARBOVAC Vapour recovery technology can treat a wide range of products for following applications: Gasoline (all grades) Crude oil Distillate fuels Naphtha Paraxylene, etc. Thanks to our joint ventures with local companies around the world, we offer a reactive and effective service to our customers. Suppliers are chosen based on strong quality criteria including fully operational network to assure permanent availability of spare-parts. 100 VRUs installed in more than 22 countries Truck/rail loading facilities Top and bottom Marine loading facilities Ships and barges Storage tank facilities Filling - Transfer - Breathing Thanks to the vacuum capacity of our screw pumps, the most stringent emission limits can be reached (1mg/m 3 for benzene vapours & 50mg/m 3 for hydrocarbons), without any additional features. We can provide an emission limit within g/m 3 and mg/m 3 range! Partners network Without Vapour Recovery Unit, VOC emissions represent 1 kg/m 3!!! 2 3

3 Activated carbon & dry screw vacuum pump technology Air HydrocarbonS Absorbent Product Valve open Valve Closed Your benefits Return on Investment (ROI) > In the form of product recovered > Mostly within months Selling the recovered product that would otherwise be lost (emitted into the atmosphere or burned in a combustion unit) allows the user to compensate its investment in less then 3 years. The recovery process in 3 steps: 1 - Adsorption of the hydrocarbons on activated carbon 2 - Regeneration of the carbon by means of vacuum by dry vacuum pumps 3 - Re-absorption of the hydrocarbons in a liquid product Reliable process: > Engineering reduced to the essentials > No glycol: no glycol heat exchanger, no glycol circulation & no separator Activated carbon: Activated carbon is the most used absorbent in the vapour recovery industry. It comes from carbonization and activation of mineral charcoal. CARBOVAC uses activated carbon for its high adsorption capacity. Strong durability of the vacuum pump > Robust design > No internal touching parts, no internal wear > Extended service lifetime, first overhaul not before > operating hours Dry Screw Vacuum Pump: CARBOVAC was the first company to use dry screw vacuum pump process in the vapour recovery units industry. This technology aims to replace former technologies using liquid ring vacuum pumps, rotary vane and rotary lobe vacuum pumps. It significantly improves energy consumption while reducing maintenance costs efficiently. Dry screw pump eliminates the use of a seal liquid and its related corrosion & abrasion. Contrary to liquid ring pump, dry screw pump can be speed controlled: This opens the possibility to adapt capacity requirement seamlessly to variable flow rates and concentrations in the vapour mixture present into the VRU. 4 Low maintenance costs > No corrosion or abrasion > Simple process > High quality equipment selection through approved vendor list The use of Variable Frequency Drivers (VFD) combined with a highly developed automation system improves dramatically energy consumption management. CARBOVAC s vapour recovery technology is today the most used technology in the market. Low energy consumption > Regeneration energy proportional of the mass of HC absorbed > All motors equipped with VFDs > Truck & marine loading < 0.12 kwh/m3 of vapour treated Longevity of the activated carbon > 15 years > Reverse flow (no dusting) > Pressure controlled desorption process > Optimized pore size distribution > Low pressure drop Lifetime after sales support guaranteed on our equipment 5

4 Automation & Safety Logistics CARBOVAC has developed a powerful & reliable automation system*: CARBOVAC has the ability to perform complete doorto-door services for the delivery of general, heavy and oversized cargo from any worldwide location. Continuous emission report with historical records High level of availability and disponibility SCADA monitoring system Open communication & architecture system Intrinsically safe system Alarm & default management Remote control capability SIL 2 /SIL 3 capability (upon request) We have a worldwide network of partners, that enables us to export or import anywhere in the world and handle specific requirements like import. We are able to ship VRU by air or sea optimizing the cargo space for shipping containers use. Our customers can rely on our shipping specialists to take care of all the shipping transactions including customs clearance and delivery at destination. * Siemens & Allen Bradley PLC manufacturers Our Vapour recovery units are in conformity with ATEX Directive 1999/92/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres. All our VRUs meet the highest level of safety, our units are entirely explosion-proof designed in order to withstand the pressure of a potential internal explosion. Our VRUs are installed in environments containing combustible liquid and explosive gases with a high risk of fire and explosion; therefore our VRUs are designed with a stringent safety philosophy: VRU is delivered fully ATEX appraised Risk analysis performed in particular HAZOP and SIL studies Explosion proof designed system Temperature at the outlet of the vacuum pumps is maintained at less than 50 C Flame arrestor protection at the inlet line Level transmitter, high-high and low-low level switches on the column Two positive closing valves in each absorbent circulation line 6 Our vapour recovery units can also be manufactured locally After Sales Services Powerful & reliable automation system ATEX conformity Zone 1 Gas group G CARBOVAC provide customized reliability solutions to meet your specific needs, from maintenance effectiveness assessment to full contract of your choice: Tele-maintenance & hotline support Critical spare-parts inventory optimization On-site customer maintenance team & local support training Revamping Access to our dedicated computerized Maintenance Management System Periodical calibration The lifetime satisfaction of our clients is our highest priority 7
