Siemens Energy has received orders for the compressor trains
for three LNG
(liquefied natural gas) plants in China for liquefying
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
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
"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."
