Hydrocarbon Vapour Recovery Solutions
Activated carbon & dry screw vacuum pump technology
2 3
Thanks to the vacuum capacity of our screw pumps, the most stringent emission limits can be reached (1mg/m3 for benzene vapours & 50mg/m3 for hydrocarbons), without any additional features.

Why Emission Control?
We can provide an emission limitwithin g/m3 and mg/m3 range!
Without Vapour Recovery Unit, VOC emissions represent 1 kg/m3 !!!
100 VRUs installed in more than 22 countries
That is why such VOC emissions have to be controlled.
Our vapour recovery units meet worldwide legal re-quirement 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.
• Gasoline (all grades)• Crude oil• Distillate fuels• Naphtha• Paraxylene, etc.
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 reco-very unit systems throughout the industry. Our Vapour Recovery Units are provided with a reliable process management system en-suring a high safety & availability rate with lowest energy consumption and higher carbon lifetime expectancy.
Our extensive know-how & experience on the VRU process using dry screw vacuum pumps (to rege-nerate the activated carbon), is recognized for its simplicity and reliability by many global oil & gas and storage companies on the market.
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 availa-bility of spare-parts.
Volatile Organic Compounds (VOC) emissions resulting from the storage of petrol and its distri-bution 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 (flammablevapours,explosionrisks)
CARBOVAC Vapour recovery technology can treat a wide range of products for following applications:
Truck/rail loading facilitiesTop and bottom
Marine loading facilitiesShips and barges
Storage tank facilitiesFilling - Transfer - Breathing

Return on Investment (ROI) > In the form of product recovered > Mostly within 10-30 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.
Low maintenance costs > No corrosion or abrasion > Simple process > High quality equipment selection through approved vendor list
Reliable process: > Engineering reduced to the essentials > No glycol: no glycol heat exchanger, no glycol circulation & no separator
Strong durability of the vacuum pump > Robust design > No internal touching parts, no internal wear > Extended service lifetime, first overhaul not before > 40 000 operating hours
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

The use of Variable Frequency Drivers (VFD) combined with a highly developed automa-tion system improves dramatically energy consumption management. CARBOVAC’s vapour recovery technology is to-day the most used technology in the market.
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 consump-tion 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.
Activated carbon & dry screw vacuumpump technology
Activated carbon:
Activated carbon is the most used absorbent in the vapour recovery industry. It comes from carboniza-tion and activation of mineral charcoal. CARBOVAC uses activated carbon for its high adsorption capacity.
The recovery processin 3 steps:
1 - Adsorption of the hydro- carbons 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

Our VRUs are installed in environments contai-ning 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
Our vapour recovery units can also be manufactured locallyOur Vapour recovery units are in conformity with ATEX Directive 1999/92/EC concerning equip- ment 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.
