Praxair China Shanghai; www.praxair.cn) has signed a new contract to expand supply with its existing customer, Jinlong Copper Co. (www.jinlongcopper.com), the largest copper-smelting joint venture (JV) in China, located in Tongling, Anhui in Eastern China.
Praxair China will invest to double the oxygen production capacity of its air separation unit in Tongling, to approximately 700 ton/d. Praxair will also acquire Jinlong’s existing, captive plants and integrate them with its plants that have been supplying industrial gas for Jinlong Copper’s flash furnace-smelting process.
Jinlong has also been utilizing Praxair’s patented oxy-fuel burner applications technology, Dilute Oxygen Combustion, in its anode furnace for its high flame luminosity, wide flame coverage and highly effective heat transfer characteristics to further improve energy efficiency and reduce emissions.
