Siemens Energy will supply together with its Chinese joint
venture SITHCO (Siemens Industrial Turbomachinery Huludao Co.
two pre-engineered integrally geared compressors for an air
separation plant to China.
The purchaser is Hangzhou Hangyang Co., a company
specialized on technology, energy, petrochemical and industrial markets
worldwide with a 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 in early 2013. Financial terms of
the deal were not disclosed.
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, the company said.
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, the company said.
In the air separation process, the compressor efficiency is
of utmost importance, according to Siemens.
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
Pre-engineering of compressor components allows reducing
lead time and costs. The use of well proven components ensures
plant reliability and availability, the
"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 oil and gas division.
"Based on our proven integrally geared turbo compressors,
these units are specifically designed as main air compressors
for air separation plants featuring low capital expenditure
combined with outstanding efficiency performance, he
