FEED GAS PRETREATMENT IN SYNTHESIS GAS PRODUCTION

摘要

AN AIR SEPARATION SYSTEM (3) AND A PARTIAL OXIDATION SYSTEM (11) FOR THE PRODUCTION OF SYNTHESIS GAS ARE INTEGRATED WHEREIN THE AIR SEPARATION SYSTEM (3) PROVIDES THE OXYGEN FOR THE PARTIAL OXIDATION PROCESS (11) AND BYPRODUCT NITROGEN (7) IS UTILISED TO GENERATE REFRIGERATION FOR PRETREATMENT OF THE PARTIAL OXIDATION FEED GAS. THE PARTIAL OXIDATION FEED GAS IS PREDOMINANTLY METHANE, AND TYPICALLY IS OBTAINED FROM NATURAL GAS WHICH CONTAINS LIGHTER COMPONENTS SUCH AS NITROGEN. (FIG. 1)
