Booster compressors are used to restore the pressure drop from these losses. Gas transmission through pipelines results in pressure drop because of friction losses. Compressors, applied to these services, have large compression ratios, high power requirements, and low volume flow rates. Reinjection compressors also are used for underground storage of natural gas.
Reinjection compressors can be required to deliver gas at discharge pressures in excess of 10,000 psi. The reinjection of natural gas is employed to increase or to maintain oil production. Many gas lift compressors are installed on offshore facilities. Gas lift compressor duty is frequently of low to medium throughput with high compression ratios. Gas lift compressors are frequently used in oil handling facilities where compression of formation gases and gas lift gas is required. Flash gas compressors typically handle low flow rates and produce high compression ratios. These are:įlash gas compressors are used in oil handling facilities to compress gas that is “flashed” from a hydrocarbon liquid when the liquid flows from a higher pressure to a lower pressure separator.
Installation, safety, and maintenance considerations also are discussed in their erspective pages.Ĭompressors used in the oil and gas industry are divided into six groups according to their intended service. Major components and construction features of centrifugal and reciprocating compressors are emphasized.
