Siemens Energy has received orders for the compressor trains for three LNG (liquefied natural gas) plants belonging to Hangzhou Zhongtai Cryogenic Technology Corporation in China for liquefying synthetic natural gas. This marks the fifth follow-up order for Siemens from this company.
These plants have a capacity of 0.5M m3 of gas per day. One of the plants will be operated by the Houma Tongsheng Yitong Natural Gas Company. The machines are expected to be ready for operation by June 2014, after a delivery period of only 12 months.
The compressor trains in the three plants each consists of a six-stage vertically split compressor (barrel-type compressor) and a Siemens constant-speed electric motor. This type of drive and control using inlet guide vane assemblies provides more efficient and reliable operation than conventional compressor solutions with throttle valve or speed control. The Siemens compressor trains compress the mixed refrigerant that cools the natural gas.
The compressor trains will be entirely fabricated, assembled and packaged with the drives in Huludao, China. This enables Siemens to provide nearly the complete value-added for small LNG compressors based on international standards from China. Siemens has developed and put into operation a pre-engineered compression concept for plant capacities between 300,000 and 1.2M m3 of gas per day.

“Excellent cooperation and the quality of the compressors fabricated in Huludao are what convinced us to order more machines from Siemens”, explained Zhang Youhu, general manager of Hangzhou Zhongtai Cryogenic.
