Reciprocating compressors have long been serving the petroleum, chemical, and natural gas industries with reliable performance. The reciprocating compressor units designed and manufactured by China Energy Green Technology strictly follow the latest international and domestic standards such as API618, and incorporate advanced technologies from both home and abroad. The compressed gas for reciprocating compressor units are generally hydrogen, natural gas, alkanes, carbon monoxide, carbon dioxide, nitrogen-hydrogen gas, desorption gas, feed gas, and other single or mixed gas. They are widely used in petroleum refining, natural gas liquefaction, hydrogen production facilities, hydrofining units, reforming units, gasoline, diesel, and kerosene environmental upgrading facilities, coalbed methane to methanol, coke oven gas to methanol, ethylene plants, propylene plants, coal-to-olefins, coal-to-liquids, polysilicon plants, and ASU package, etc.
