EXPANDER-COMPRESSOR

Details

Evaluate this Device

Expander-compressor is a unit used in process cycles to lower the temperature of gas and to increase the pressure of process gas due to operation of the compressor stage.

Expander-compressor units are designed to produce deep cold in natural gas preparation and treatment units, providing temperature difference up to 55°C.

For low-temperature preparation of natural gas as well as its cooling for subsequent transportation.
For gas processing at gas treatment plants by low-temperature separation of heavy fractions from natural gas.
For production of various technical gases (O2, N2, Ar etc.) in air separation plants by their low-temperature separation from air.
In chemical and petrochemical industry, during production of olefins, ammonia, nitric acid, hydrogen etc. (low-temperature separation of different compounds in gaseous form).
For production of liquefied natural gas.
