Siemens to supply compression solutions for LNG plant in Malaysia

Published on: 

Siemens Energy has been awarded a contract for supplying turbo compressors and mechanical drive gas turbines for a major Liquefied Natural Gas project in Malaysia. The project will help to improve overall plant efficiency and minimize gas flaring at the Petronas Bintulu LNG Plant in Sarawak, East Malaysia.

The target of the multimillion-dollar LNG project is to re-liquefy excessive Boil-Off Gas (BOG) evaporating out of the LNG storage tanks, and currently flared. It will deploy the world's first gas-turbine-driven cryogenic-temperature BOG turbo compressor from Siemens.


The LNG project is implemented by MLNG (Malaysia LNG), a subsidiary of Petronas. Engineering, procurement, and construction management (EPC) is contracted to Munich-based LINDE Engineering. These companies are thus pioneering world-scale Boil-Off Gas re-liquification within LNG plants and are implementing technology from Siemens to improve efficiency and help to reach international emission standards.

The scope of supply covers the engineering, manufacturing and testing of one tandem-casing, cryogenic-temperature BOG turbo compressor and one single-casing LNG-refrigerant turbo compressor. Both compressors will be direct-driven by Siemens SGT-700 mechanical drive gas turbines. Project completion is expected in April 2014, and the plant will start operation in October 2014.
