Other Industries
Vapor recovery is also used in the chemical process industry to remove and recover vapors from storage tanks. The vapors are usually either environmentally hazardous, or valuable to be recovered. The process consists of a closed venting system from the storage tank ullage space to a vapor recovery unit (VRU) which will recover the vapors for return to the process or destroy them, usually by oxidation.
Vapor recovery units are also becoming commonly used in the oil and gas industry as a means of recovering natural gas vapor and making it a usable and profitable product. Specifically a newer form of vapor recovery technology, Ejector Vapor Recovery Units create a closed loop system which not only recovers valuable vapor, but also reduces methane and VOC emissions.

Famous quotes containing the word industries:
“All industries are brought under the control of such people [film producers] by Capitalism. If the capitalists let themselves be seduced from their pursuit of profits to the enchantments of art, they would be bankrupt before they knew where they were. You cannot combine the pursuit of money with the pursuit of art.”
—George Bernard Shaw (1856–1950)
