Abstract:
1. A method for destroying and/or altering biological and/or chemical contaminants within a feed fluid stream, comprising: a) introducing the feed fluid stream into a cold pass of at least one recuperator; b) introducing said feed fluid stream into a compressor, and compressing said fluid stream to an elevated pressure, resulting in heating of said fluid stream to an elevated temperature sufficient to destroy and/or alter said biological and/or chemical contaminants within said feed fluid stream; c) passing at least a portion of the compressed and heated fluid stream from said compressor through a hot pass of said recuperator and thereby causing heat to be transferred to said feed fluid stream passing through cold pass; and d) providing a heater between said recuperator and said compressor and heating said feed fluid stream with said heater prior to entering said compressor.
