Siemens to supply main refrigerant compressor solution for LNG plant in China
Siemens Energy has received an order to supply a complete main refrigerant compressor train to China. Purchaser is Shaanxi Zhongyuan Green Energy Natural Gas Company Ltd. The Siemens solution consists of a 0.2 MTPA (million tons per annum) electric-motor-driven centrifugal compressor to be installed in a Liquefied Natural Gas (LNG) plant in Dingbian City, Shaanxi province. Plant start-up is scheduled for the second half of 2011.
The Siemens scope of supply encompasses the complete motor-driven refrigerant compressor train, which consists of an SV(10-7-B) centrifugal compressor and an 11 megawatts fixed-speed electric motor. Siemens will also supply the gearbox, lube oil system and unit control system. The LNG liquefaction process in this plant is comparable to the one used in Sengkang LNG plant in Indonesia, where Siemens provided the liquefaction plant (four motor driven trains with a capacity of 0.5 MTPA each), the power plant (two SGT-1000F gas turbines) and the entire electrical transmission and distribution equipment, and the communications system.
“This order reconfirms Siemens‘ leadership in all-electric solutions for oil and gas applications,” said Tom Blades, CEO of the Siemens Oil and Gas Division. “We’re supplying cutting-edge compression technology with an electric drive to provide a reliable, environmentally friendly and efficient solution for the LNG plant.” The market for LNG in China shows high growth rates.
Siemens was contracted among other reasons for its unique value proposition. For example the compressors‘ first stage impeller of each process stage is equipped with adjustable inlet guide vanes (IGVs) allowing additional throughput and wide turndown at high efficiency. Furthermore, the IGVs allow greater power savings compared with a throttling-valve flow control device and Vorecon speed control device.
