Siemens to supply first pre-engineered integrally geared air compressors to China
Siemens Energy will supply together with its Chinese joint venture SITHCO (Siemens
Industrial Turbomachinery Huludao Co. Ltd.) the first two large size, pre-engineered
integrally geared compressors for an air separation plant to China. Purchaser is Hangzhou
Hangyang Co. Ltd, a company specialized on technology, energy, petrochemical and
industrial markets worldwide with a unique portfolio of products, services and solutions,
providing large, medium and small size Air Separation Units as well as petrochemical
equipment. The new air separation unit will supply gas for a nonferrous metal smelting
plant in the city of Fangchenggang in the Guangxi Zhuang Autonomous region in Southern
China. The plant will go online begin of 2013.
The Siemens scope of supply encompasses two STC-GC compressors, each with three stages,
including gear type coupling, lube oil unit, inlet expansion joint and other auxiliary systems.
SITHCO as local Chinese supplier will be responsible for gas coolers, gas/oil/water piping and for
the supervision of erection and commissioning on site. The inlet volume flow of the pre-engineered
compressors is about 200,000 m³ air per hour. In the air separation process the compressor
efficiency is of utmost importance.
The extension of the STC-GC compressor series covers the 120,000-400,000 m3/h capacities at a
pressure ratio of 6.5 with 3 impeller stages and adjustable inlet guide vanes for compressor
control. Pre-engineering of compressor components allows reducing lead time and costs. The use
of well proven components ensures highest plant reliability and availability.
“We are very proud about the first order for our new standardized integrally geared compressor,”
said Ralf Kannefass, head of the Turbo Equipment business segment in the Siemens Energy Oil &
Gas Division. “Based on our proven integrally geared turbo compressors, these units are
