Abstract 1. IN A PROCESS FOR MANUFACTURING HIGH PURITY BY A TRAIN OF STEPS COMPRISING REACTING HYDROCARBON WITH OXYGEN-AFFORDING GAS AT CONDITIONS INCLUDING A PRESSURE BELOW 900 P.S.I.G. AND ELEVATED TEMPERATURE TO FORM A GAS MIXTURE COMPRISING H2, CO AND CO2, REACTING CO IN THE MIXTURE WITH H2O TO FORM ADDITIONAL H2 AND CO2, AND REMOVING THE CO2 TO PROVIDE HIGH PURITY HYDROGEN, THE IMPROVEMENT FOR PROVIDING THE HIGH PURITY HYDROGEN AT ELEVATED PRESSURE WHICH COMPRISES: (A) CENTRIFUGALLY COMPRESSING WITH A CENTRIFUGAL COMPRESSOR THE GAS MIXTURE COMPRISING H2 AND C02 FROM THE PRESSURE BELOW ABOUT 900 P.S.I.G. TO A SUBSTANTIALLY HIGHER PRESSURE ABOVE 900 P.S.I.G., SAID MIXTURE CONTAINING SUFFICIENT CO2 SO THAT THE MOLECULAR WEIGHT OF THE MIXTURE IS AT LEAST 4; THEN (B) REMOVING CO2 FROM SAID COMPRESSED GAS BY ABSORBING CO2 IN A PHYSICAL ABSORBENT AT A PRESSURE ABOVE 900 P.S.I.G. TO THUS OBTAIN SAID HIGH PURITY HYDROGEN; (C) PASSING THE HIGH PURITY HYDROGEN TO A HYDROCONVERSION ZONE, AND REACTING SAID PURIFIED HYDROGEN WITH HYDROCARBONS IN SAID HYDROCONVERSION ZONE; (D) WITHDRAWING A HOT EFFLUENT FROM THE HYDROCONVERSION ZONE AND PASSING SAID HOT EFFLUENT THROUGH A STREAM BOILER TO GENERATE STEAM; AND (E) USING SAID STEAM TO DRIVE THE CENTRIFUGAL COMPRESSOR THROUGH A STREAM TUBINE LINKAGE FOR SAID CENTRIFUGAL COMPRESSING.
