Vapor recovery units

Based in PSA (Pressure Swing Adsorption) technology of adsorption/absorption in active carbon beds to comply with 94/63/EC Directive on the control of Volatile-Organic-Compound (VOC) emissions, limiting the explosive atmosphere creation and favoring operative surroundings more insurance.

The basic vapor recovery unit system is comprised of a PSA (Pressure Swing Adsorption) process with two activated carbon bed vessels, alternating on a 15 minute time cycle.

Regeneration of the carbon reactors is accomplished primarily by vessel evacuation with two stage liquid ring vacuum pumps to a pressure level of -27”Hg (3”Hg absolute) and secondarily with an ambient air purge input to the bed in a controlled manner during the last 25% of the regeneration cycle.

All product recovered by the system is pumped back to the gasoline supply tank where the enriched liquid gasoline is allowed to disperse throughout this causing minimal changes in final product characteristics.

Designed under license, we manufacture our VRUs in Spain. This, together with the best after sales service for spare parts, repair and maintenance, thus as the 15 units installed and plenty operatives through Spain and Portugal are the best warranty for our customers.
