Siemens to supply new compressor trains for three LNG plants in China

08.08.2013  | 

The compressor trains in the three plants each consists of a six-stage vertically-split 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.

Siemens Energy has received orders for the compressor trains for three LNG (liquefied natural gas) plants in China for liquefying synthetic natural gas, the company said on Thursday.

The customer is the Hangzhou Zhongtai Cryogenic Technology, marking the fifth follow-up order for Siemens from this company. The Houma Tongsheng Yitong Natural Gas Company will operate one of the plants.

These plants have a capacity of 500,000 standard cubic meters/day of gas. The machines will be handed over to the customer in June 2014, after a delivery period of 12 months, according to Siemens officials.

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. 

Siemens notes that 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 also 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.

"Our worldwide compressor business profits from local engineering and production expertise," said Lennart Nilsson, head of the compression unit for Siemens Energy. 

"This also benefits our customers, who receive the same standards wherever they may be in the world," he continued. "This allows us to flexibly and promptly serve the important LNG market for small and medium-size plants."
