The turbo-expander process for treating gas streams for high liquid recovery was developed in the early 1960s. These plants replace the chiller or J-T valve with an expansion turbine and are capable of cooling the gas to 160 °F ( 107 °C). The main application of the turbo-expander is to improve the recovery of ethane from natural gas.
As the gas flows from the high pressure stream into the turbo-expander, the gas spins the turbine, which is coupled to a generator that produces electricity. Thus, by replacing a conventional control valve or regulator with a turbo-expander, the energy contained in the motive stream, that would otherwise be lost, can be converted to electricity.Turbo-expanders and Cryogenic Liquid Pumps for sale of Cryogenic Gas Turbo ExpanderASPG supplies the booster turbo-expanders in the air separation plants with the capacity of 1000Nm 3 /h~100,000Nm 3 /h, in the gas liquefaction plants with the capacity up to 500 T/d and in the natural gas (associated gas) liquefaction & separation plants with the capacity up to 10 million Nm 3 /d and the inlet pressure up to 10.0 MPa.Turboexpanders defined - Cryogenic Society of AmericaSep 22, 2015The use of turboexpanders in cryogenic plants has been the result of several technological advances.
