Patent ID: 8840842

Claim:
A system for purifying a gaseous feed fluid stream by reducing biological and/or chemical particulate contaminants entrained within a said gaseous feed fluid stream, comprising: a) at least one recuperator for receiving from a source said gaseous feed fluid stream with said biological and/or chemical contaminants entrained therein, said recuperator comprising a cold pass and a hot pass, wherein said contaminated gaseous feed fluid stream with said biological and/or chemical contaminants entrained therein is introduced into said cold pass; b) a compressor for receiving said gaseous feed fluid stream with said biological and/or chemical contaminants entrained therein from said cold pass of said recuperator, said compressor operable to compress said gaseous fluid stream to an elevated pressure and thereby heat said gaseous fluid stream to an elevated temperature sufficient to destroy and/or alter said biological and/or chemical contaminants entrained within said gaseous feed fluid stream resulting in a compressed purified gaseous feed fluid stream; and c) passing at least a portion of said compressed purified gaseous fluid stream from said compressor through said hot pass of said recuperator while maintaining said elevated temperature as said compressed purified gaseous fluid stream enters said hot pass and thereby causing heat to be transferred from said compressed purified gaseous feed fluid stream to said gaseous feed fluid stream with said biological and/or chemical contaminants entrained therein passing through said cold pass.
