MAN supplies compressor technology for a major CTL project in China

Gerald Ondrey

MAN Diesel & Turbo SE (Augsburg, Germany; has been awarded the contract for a major project to construct eleven turbomachinery trains in China. The contract value is in excess of €125 million.

The site of the project is Yinchuan in the Ningxia region where air separation units (ASUs) are being built under the management of Linde and Hangyang for one of the world’s largest coal-to-liquids (CTL) plants.

The chemical process used requires huge quantities of oxygen. The turbomachinery ordered will be used in an ASU that will generate about 40,000 ton/d of oxygen.

The plant is operated by the Shenhua Ningxia Coal Industry Group Co.

“This major contract is confirmation that we have identified today’s demands for such mega-plants at an early stage and responded accordingly“, says ReneĢ Umlauft, CEO of MAN Diesel & Turbo. “The MAX1 axial compressor used in all eleven machine trains was the most challenging compressor development project in the company’s history and has proved its worth yet again.“

Each machine train consists of three different MAN products: a six-stage MAX1 axial/centrifugal compressor type AR115/06M with high-pressure radial component, an also six-stage integrally geared compressor type RG 56-6 and a condensing steam turbine DK080/250R, acting as the driver for both compressors.

The MAX1 axial compressor is regarded as a technical landmark — the result of several years of intensive development work that was completed in 2011. Together with German partner MTU Aero Engines (Munich, Germany), MAN Diesel & Turbo has combined for the first time in this configuration the advantages of industrial compressors — robust design and high efficiency — with the advantage of gas turbine compressors and aircraft engines, the exceptionally high power density.
