In 1976, SASPG was appointed by the China central government to research and develop the turbo-expander unit for natural gas liquefaction and separation plants. Integrating the advanced technology introduced from abroad in China's 8th Five-Year Plan period and the experiences acquired within 40 years of manufacturing, SASPG manufactures the best turbo-expanders in China, which feature higher expansion ratio, more enthalpy drop, more liquid content in expanded gas and higher efficiency. The expanders have been exported to many countries such as the Philippines, Syria, India, Myanmar and Turkey.
ASPG supplies the booster turbo-expanders in the air separation plants with the capacity of 1000Nm3/h~100,000Nm3/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 Nm3/d and the inlet pressure up to 10.0 MPa. Almost all the turbo-expanders used in all the large oil fields are supplied by SASPG. In recent years, SASPG has developed this type of natural gas (air) pressure power generation expander and all liquid expander, of which natural gas (air) pressure power generation expander’s generating capacity is up to 4000KW and has been used in industry.
