<P>PROBLEM TO BE SOLVED: To provide a multistage sulfur removal system and to provide a process for an auxiliary fuel system. <P>SOLUTION: The system for producing an auxiliary fuel stream containing a low concentration of sulfur compounds from a primary fuel stream includes a first separation stage to separate a portion of a primary fuel stream into a first vapor permeate stream and a first retentate stream, a first separation stage partial condenser connected to the first vapor permeate stream condensing a portion of the first vapor permeate stream into a first liquid stage stream and a first vapor stage stream, and a second separation stage partial condenser condensing a portion of the first vapor stage stream into a second liquid stage. The first vapor permeate stream is preferably sent through a vapor phase reactive desulfurization catalyst reactor to condition any sulfur compounds present into species that can be easily separated from the fuel stream. <P>COPYRIGHT: (C)2013,JPO&INPIT |
