Vapor Recovery

Vapor Recovery Units

Hydrocarbon vapors are usually either environmentally hazardous or too valuable not to be recovered. The recovery 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.

Vapor recovery units are commonly used in the oil and gas and chemical industries 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.

Vapor Recovery Towers

Vapor recovery towers are used in the oil and gas industry to provide flash gas recovery at near atmospheric pressure without the potential of oxygen ingress from the top of the storage tank. The ability to create the vapor flash inside the vapor recovery tower often reduces storage tank emissions to less than 6 tons per year.
