The article focuses on the oxygen-enriched air provided for passengers traveling along the Quinghai-Tibet Railway in China and Tibet. At high altitude, the oxygen available in air is decreased and can cause breathing difficulties. Air Products has supplied the trains with its Prism membrane separators to produce oxygen-enriched air that goes into the compartments, resulting in an oxygen content of about 23%. The membrane separators separate gases by permeation to produce purified-oxygen and nitrogen.
