Praxair China starts-up new plant in Tongling


Under the terms of a long term cooperative agreement, Praxair China recently started up its new air separation plant for Jinlong Copper Co. Ltd in Tongling, Anhui Province.

The facility represents the third plant owned and operated by Praxair for Jinlong Copper, and the fourth plant built overall by Praxair for Jinlong’s flash furnace-smelting process.

Praxair and Jinlong, the largest copper smelting joint venture in China, have a 15-year cooperative agreement for the supply of oxygen for its operations. Prior to the new plant, Praxair had already built three non-cryogenic vacuum pressure swing adsorption (VPSA) plants for its esteemed customer.
