Air Liquide has ordered an innovative compressor train from the Dresser-Rand business, part of the Siemens Power and Gas Division, to be used in an air separation plant (ASU) in China.

Delivery of the equipment is scheduled for July 2017, with commercial operations expected to commence in March 2018.

The cryogenic ASU, located in Dalateqi, will supply industrial gases including oxygen (O2) and nitrogen (N2), to produce light hydrocarbons.

The compressor train includes the newly-developed Siemens STC-SI main air compressor, an STC-GV (H) booster air compressor, and an SST-600 steam turbine.

“The new STC-SI compressor series was designed for high efficiency and reliability. It sets a new efficiency standard for large air separation plants and represents a breakthrough for Siemens and the Dresser-Rand business,” said Christopher Rossi, CEO of the Dresser-Rand business.
