Air Products confirmed that its four air separation unit (ASU) trains, built for Shaanxi Future Energy Chemical Co., Ltd. in Yulin City, Shaanxi Province, China, have been brought fully on-stream.

The project is capable of producing 12,000 tonnes per day of oxygen (O2) and significant tonnage volumes of nitrogen (N2) and compressed dry air for the customer’s coal chemical plant.

This represents one of the largest, single, on-site ASU orders ever committed to an industrial gas company. The gases produced by this ASU at Yulin are used to help manufacture one million tonnes of high quality oil products each year.

The four ASU trains are equipped with advanced air compressors as well as design and technology developments to enhance energy efficiency.

Phil Sproger, Vice President of Asia On-Site Business Development, commented, “This is a great milestone for Air Products and thanks to Shaanxi Future Energy Chemical for their trust in us to supply the very large industrial gas demand of such a monumental project. The successful execution of this world-scale project is another testimonial of our leading position in large air separation and excellence in safety, reliability and technology.”

Since 1987, Air Products has been operating in China and has built several ASU facilities in the country, supplying large tonnage quantities of industrial gases to significant energy projects for customers such as Weihe Clean Energy Co. and Pucheng Clean Energy Co., both also based in the Shaanxi Province. The Tier One business is currently building another multi-train ASU project in the same area to support Shanxi Lu’an Mining Group’s coal-to-liquid business.

This contract has been announced just days after Praxair stated that they had also started up a new air separation unit (ASU) in Northern China. Praxair’s plant will provide 3,000 tonnes of both O2 and N2 for the Yankuang Guohong Chemical Co., Ltd facility in Zoucheng City.
