Abstract

A method for removing hydrocarbons from a stream of compressed air for use in a compressed air supply and delivery system of the type wherein a supply of compressed air is provided by a lubricated or non-lubricated air compressor includes the passing of the compressed air from the lubricated air compressor through a catalytic oxidation system to remove hydrocarbons, including vapor phase hydrocarbons, from the compressed air stream. The method contemplates feeding the stream of compressed air from an outlet of the air compressor to a treatment station, which treatment station utilizes a catalytic oxidation system to remove the hydrocarbons from the compressed air stream, thereby oxidizing the hydrocarbons into carbon dioxide and water and removing a predetermined, relatively high percentage of existing hydrocarbons from the compressed air stream prior to reaching downstream portions of the delivery system and any connected utilization apparatus. A compressed air system in which the foregoing method is carried out also forms a part of the invention. The invention also extends to a catalytic oxidation system for use in removing hydrocarbons, including vapor phase hydrocarbons, from a compressed air stream.
