AIR PREPURIFICATION FOR A LARGE SCALE CRYOGENIC AIR SEPARATION PLANT
摘要
The invention relates to a process for the production of oxygen and/or nitrogen in a cryogenic air separation unit. It especially relates to a process which avoids as much as possible any build up in the process of unsaturated hydrocarbons or of any compounds in which unsaturated compounds have been incorporated. The process comprises the removal of at least unsaturated hydrocarbons from the feed air and separation of oxygen and nitrogen by cryogenic distillation, while at least producing 200 ton oxygen/day.
