News ReleaseAir Products To Provide New Ap-X™ Liquefaction Process Technology To Qatargas 3 And 4 Lng Trains In Qatar

April 20, 2005 Lehigh Valley, Pa.

Air Products (NYSE:APD) today announced the signing of two agreements to supply its new AP-X™ liquefaction process technology and key equipment to the proposed Qatargas 3 Joint Venture (Qatar Petroleum and ConocoPhillips) for Train 6, and to the proposed Qatargas 4 Joint Venture (Qatar Petroleum and Shell) for Train 7, each to be located in Ras Laffan, Qatar. Air Products provides natural gas liquefaction process technology, main cryogenic heat exchange equipment, plus other key process equipment in the AP-X process for world class process trains producing liquefied natural gas (LNG).

The feed gas will come from Qatar's North Field, the largest offshore non-associated natural gas field in the world, with proven natural gas reserves quoted in excess of 900 trillion cubic feet. Each AP-X LNG process train will be rated for an LNG production capacity of 7.8 million tons per year. Trains 6 and 7 are scheduled to be on-stream in 2009 and 2010, respectively.

Air Products' AP-X LNG process production capacity, which is 50 percent larger than any other LNG train currently in operation, is positioned well for a continuing market trend toward larger LNG process trains. "This novel AP-X liquefaction process provides a combination of proven Air Products process technologies and key liquefaction equipment in a way that provides the industry with low spigot cost, high reliability production, bankable projects and flexible operation as new markets develop," said Mark Modjeska, general manager, Worldwide Equipment at Air Products. Qatargas Trains 6 and 7 represent Air Products' fourth and fifth AP-X LNG process and equipment orders.

A vast majority of the total worldwide baseload LNG production capacity is produced with Air Products' technology. Air Products has designed, manufactured and exported over 70 LNG heat exchangers over the last 35 years. In support of the LNG industry, Air Products provides process license and equipment for the baseload liquefaction process, dry inert gas generators for LNG carriers, shipboard membrane nitrogen systems, membrane nitrogen and natural gas dehydration membrane systems for offshore platforms, and land-based nitrogen plants for the baseload LNG facility and LNG import terminals.
