The Linde Group will build six major air separation units for Shenhua Ningxia Coal Industry Group Co. Ltd and Shenhua Logistics Group Co. Ltd in Yinchuan in the Ningxia Hui Autonomous Region in Northwest China.

The companies recently signed a contract to this effect. Shenhua Ningxia is a member of Shenhua Group Co. Ltd, the largest coal chemical company in China.

“We are delighted to start cooperating with Shenhua Group and contribute our in-depth expertise in air separation technology,” said Prof Dr Aldo Belloni, Member of the Executive Board of Linde AG. “The project further strengthens our position as a leading gases and engineering company in China,” he added.

The air separation units will each supply around 100,000 normal cubic meters of gaseous oxygen per hour (Nm³/h) to Shenhua Ningxia’s Coal-to-Liquid (CTL) complex at Ningdong Energy Chemical Base. The oxygen will be used for the production of four million tonnes of CTL - mainly liquid fuels derived from coal - per year, making this one of the largest Coal-to-Liquid projects worldwide.

Linde will be responsible for the engineering, supply of machinery and equipment, supervision services at the job site, turnkey supply of the cold boxes and training the buyer’s personnel. The air separation units are scheduled to go on stream in 2015.
