Application of Compressor Equipment in Oil & Gas Refining

Compressors constitute an important part of the mechanical equipment in oil and gas refineries and petrochemical plants. Compressors are used for different applications in the main and auxiliary process cycles:

• Recycling compressors designed to provide a steady flow of process gas through a closed circuit in order to maintain the required process parameters in the plant units (for example, hydrogen-rich gas recycling in a hydrotreater)


• Feed compressors supplying process gas to reactor


• Booster compressors


• Sales gas compressors (for example, methane).

Electrically-driven reciprocating and centrifugal compressors are most commonly used in oil and gas refining facilities.
