Vapour Recovery Units (VRU)

Vapor Recovery Units are equipment that collect vapours from storage and loading facilities, re-liquefy them and return them in the form of liquid hydrocarbons to storage tanks. Methods to recover vapours include absorption, condensation, adsorption, and simple cooling.
Gasoline contains Volatile Organic Compounds (VOCs) that evaporate easily. Evaporated vapours, in addition to their effects on human health, are harmful for the environment and represent a significant loss of sales for tank farms.
