摘要：
In addition to Nitrogen, Oxygen and Argon, ambient air contains many trace impurities. These impurities include moisture, Carbon Dioxide, Oxides of Nitrogen and light Hydrocarbons. Prior to cryogenic distillation of air to produce Nitrogen, Oxygen and Argon these trace impurities have to be removed since, some of these constitute a safety hazard in the cryogenic plant. A significant amount of information is available in the literature for the removal of Water and Carbon Dioxide from air. However, only limited information is available for the removal of other trace impurities. We discuss the results of an experimental study on the removal of these trace impurities from air.
