News ReleaseAir Products Supplies PRISM® Membrane Separators to Produce Enriched Oxygen for Qinghai-Tibet Train in China, Enabling a Pleasant Ride on Top of the World

July 17, 2006 Lehigh Valley, Pa.

Air Products (NYSE: APD)—a globally diversified gases and chemicals company—has supplied through its wholly-owned subsidiary, Permea China Limited, PRISM® membrane separators in the equipment used to produce enriched oxygen for the passenger compartments on China's Qinghai-Tibet Railway, enabling a breathe-easy train journey on the world's highest highland track.

Opened to the public on July 1, the Qinghai-Tibet Railway is the world's longest and highest highland railway. The journey from Golmud in Qinghai Province to Lhasa in the Tibet Autonomous Region is over a 700 mile long track, of which nearly 600 miles (or four-fifths of the track) are situated over 13,000 feet above sea level, with the highest point at over 16,500 feet.

At a high altitude, the available oxygen in air is decreased and can cause breathing difficulties. Air Products has supplied its PRISM membrane separators to produce oxygen enriched air that goes into the train passenger compartments and mixes with the air inside, resulting in an overall oxygen content of about 23 percent and enabling passengers' easier breathing at the high altitude.

The Qinghai-Tibet Railway is the first, and currently the only, railway in the world to use this application to overcome the breathing problem at the high altitude over the long journey.

"Air Products is proud to be able to participate in the Qinghai-Tibet Railway project, which is a landmark project in China that bridges Tibet, once not easily reachable, with the rest of the world," said Wilbur Mok, president of Air Products China. "We have leveraged our expertise and technology to overcome one of the main challenges—sufficiency of oxygen—when traveling through the Tibetan Plateau, dubbed the roof of the world."

The Qinghai-Tibet Railway is a landmark project in China to develop its western region. With the opening of this track, about 3,000 people can travel to Tibet by train daily, and it will contribute enormously to the region's economic growth.

"Our PRISM membrane separators are selected for this project because they are reliable, simple to use and light weight," added Peter Fung, general manager of Permea China.
