Jordan Technologies' units recover a variety of Volatile Organic Compounds (VOCs) in truck, rail, marine and tank breathing applications as well as crude, ethanol and natural gases.

As the largest service company for Vapour Recovery Units (VRUs) in the world market, Jordan provides service to the majority of the world’s operational VRUs, including other manufacturers’ equipment.

Basic Operation

The basic VRU system comprises a pressure swing absorption (PSA) 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 a vacuum pump to a pressure level of -27 Hg (3 Hg absolute); and secondly, with ambient air purge into the bed in a controlled manner during the last 25% of the regeneration cycle.

The VOCs desorbed from the carbon during reactor regeneration are effectively recovered in a single step process that is absorption in a packed tower, counter current flow absorber.

Supply tank absorbent is pumped on skid for use as lean oil in the absorber and as a heat exchange fluid for the vacuum pump.
All product recovered by the system is pumped back to the absorbent supply tank mentioned.
Here the enriched recovered liquid product is allowed to disperse throughout the supply tank environment.

Jordan Technologies offers both the dry vacuum pump regeneration system as well as the liquid ring regeneration system.
