Air Liquide (Hangzhou) Co., Ltd. (ALHZ) is to provide 2 sets of 90,000 Nm³/h (O₂) air separation units (ASU) for a coal-based propylene project in Ningxia Autonomous Region, northwest China.

The two units are the largest ASUs in China, and among the largest ASUs in Asia.   The two units, supplied to Shenhua Ningxia Coal Industry Group Company Limited, will produce 90,000 m³ of oxygen per hour (or 3,000 tons per day) used in the manufacture of synthetic chemicals such as methanol and propylene from the gasification of coal. This process has a high environmental efficiency. The equipment supply contract was signed in June, 2007 by Marc Ducrocq, General Manager of ALHZ in Yinchuan. The two units will be put into production by the end of 2009.
