Siemens to provide two compressor trains for LNG plant in China

Published on: 

Siemens Energy recently received an order from Chengdu Cryogenic Liquidation Equipment Co. Ltd. to provide two compressor trains for an LNG (liquefied natural gas) project. Planned

 for Etuoke Qian Qi of Inner Mongolia Autonomous Region 

with an annual capacity of 400,000 tons of LNG,

 the project is expected

to be put into operation in December 2015.

Siemens inlet guide vanes (IGV) technology is said to provide a more flexible and wide range turn down for projects adopted on large scale electric drive. At the meantime, it compensates the power loss and impact to the grid of the conventional converter solutions.


Siemens also provides the solution of recycling primary seal gas leakage back to the compressor suction, which is beneficial to LNG operators. It helps reduce operation cost and increase production efficiency.

Reusing coke oven gas

A future trend for investment could be LNG production by coke oven gas. It is expected to contribute to green economy by reusing coke oven gas to produce LNG. This in turn reduces carbon emission, while securing the source of fuel gas supply. 

This was the fifth order for Siemens from Chengdu Cryogenic and it was signed at the Siemens LNG Compressor Technology Forum 2014 in Huludao, Liaoning Province on September 16. 

This is a follow-up cooperation with Chengdu Cryogenic Liquidation Equipment after the LNG project in August this year in Cangzhou, Hebei Province. 

The Cangzhou project is a single-unit LNG production project by coke oven gas, for which Siemens supplied large scale electric drive LNG compressor trains.

Lennart Nilsson, CEO of the Compression Business Unit within Siemens' Energy Sector said the company is helping its customers to achieve their economic and ecological goals. “At the same time, we are strengthening our leading position on the Chinese market.”

Xie Le Min Chairman and General Manager of Chengdu Cryogenic Liquidation Equipment Co., Ltd. said, “Excellent quality of the compressors we ordered in the previous project is what convinced us to continue the close cooperation with Siemens.”
