Durability and reliability Extremely heavy-duty industries need extremely hard-working compressors.

Oil and gas, iron milling or petrochemical processes are intensive and downtimes expensive.

Our process gas screw compressors can do the heavy lifting.

At present, process gas screw compressor is widely used in atmospheric and vacuum distillation, tandem reforming, liquid gas recovery and torch gas recovery systems for petrochemical
and oil refining industries. Usually, operating condition for such system is hard. E.g., the process gas may contain liquid, solid particles or corrosion gas such as hydrogen sulfide; the composition level of Hydrogen is high; or the gas component change frequently and etc. This caused the plunger and valves on reciprocating compressor need being replaced and maintained frequently in the past. However, the fluid injected screw compressor can resolve these problems well.

Advantages of liquid injected screw compressor

Liquid injected process gas screw compressor takes little care about the change of the gas composition, mole mass or the pressure ratio; it can also compress gas with very little
molecular weight and keep a normal operating when the Hydrogen content in process gas changes hard.

Rotors of liquid injected screw compressor don’t touch each other and keep a suitable gap through the synchronizer gears.

Liquid will be injected during the compress process to cool and wash the rotors, thus the compressor can be applied in compressing gas which is instability or easily got polymerized.

Liquid injected can also seal the gaps between rotors, gaps between rotors and shell to raise the volumetric efficiency of the compressor.
Liquid injected screw compressor has a high reliability. It can keep a continuous and trouble-free operation over 24000 hours in most conditions.
