What exactly is a vapor recovery gas compressor unit and why should I have one? The federal government has mandated rules and regulations to limit emissions on location to meet EPA guidelines. NSPS 0000/0000, simply called “Quad O”, mandates the recovery and capture of fugitive gas emissions from oil storage tanks, vapor recovery towers, three-phase oil-water-gas separators and oil and gas heater treaters with flash gas.  Common names for vapor recovery equipment are Oil Tank Vapor Recovery Unit (VRU), Vapor Recovery Tower (VRT) and Flash Gas Booster Compressor. Typical vapor recovery units are packaged with oil flooded rotary screw compressors, rotary vane compressors or wet gas reciprocating compressors. These units are specifically designed for very low vapor recovery gas pressures with high BTU compositions and high dew point cases from all sources.

AGI Packaged Pump Systems packages these units for both traditional Oil and Gas locations as well as Renewable Natural Gas (RNG) and Biogas applications. These can be packaged per NACE for sour and acid gas applications.

AGI Packaged Pump Systems’ Vapor Recovery Units can be equipped with natural gas engines, electric drives, or any other drive preference. Auto speed control and VFD’s maintain the efficient trending of compression rates required, based on the vapor stream pressure encountered. Additionally, precision electronic or electronic/pneumatic bypass/recirculation valve systems are used to maintain high run times and minimize premature shutdowns in the event of low vapor pressure events. AGI Packaged Pump Systems’ units encompass the use of latest technology PLC controls ensuring the highest level of automation, control, and safety, resulting in the highest level of protection for the operations personnel and equipment.
