Praxair Inc.'s patented technology, Dilute Oxygen Combustion, has been installed for the first time in China, at Jinlong Copper Co. Praxair China's applications technology team designed, fabricated and installed a complete dual-fuel Dilute Oxygen Combustion system for a 400-ton anode furnace at Jinlong Copper, replacing an existing air-fired system. The results were fuel savings of more than 60% and flue gas emissions reduction of more than 70%. Additional benefits to Jinlong Copper include higher furnace productivity and low maintenance. Jinlong Copper plans to install the Praxair system on a second anode furnace in the first quarter 2010. Praxair's Dilute Oxygen Combustion technology provides higher energy efficiency and furnace operation flexibility at lower capital cost. This technology uses high-momentum fuel and oxygen jets to provide strong in-furnace gas recirculation, promoting uniform flame, uniform heat release pattern and ultra-low nitrogen oxide (NOx) emissions. A dual-fuel capability allows the customer to use the lowest cost fuel available at any given time.

Praxair Inc. has received a major order from the Indian Oil Corporation Ltd. for the long-term supply of hydrogen and nitrogen gases to its new 300,000 barrels per day greenfield oil refinery which is being built at Paradip, Orissa on the eastern coast of India. Praxair will build a 90 million standard cubic feet per day hydrogen plant and a 500 tons per day nitrogen plant at the Paradip refinery. Start-ups of the plants are scheduled for the first quarter of 2012 when the refinery will be commissioned. IndianOil's refinery will use the hydrogen to enable the processing of various crude oil slates and the production of low sulfur, clean fuels.
