TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In the process (P1), the second membrane stream is compressed prior to be processed in the dehydration unit. The second membrane stream is processed in the dehydration unit prior to being compressed. Then steam is added to the high pressure syngas for the water gas shift reaction. The process further involves 1) removing the sulfur compounds present in the water gas shift effluent in a sulfur recovery unit to form sweet effluent stream that is heated and then introduced into the membrane unit; 2) removing the sulfur compounds present in the high pressure syngas stream to form sweet high pressure syngas stream that is heated and then introduced into the water gas shift unit. The sweet high pressure syngas stream is heated and steam is added for the water gas shift reaction. The water gas shift effluent is cooled to a temperature that is suitable for the membranes downstream. The portion of the high pressure non-condensable mixture is recycled to the cryogenic purification unit and the remaining portion of the high pressure non-condensable mixture is routed to second water gas shift reactor where it is further processed to further increase the hydrogen concentration in the high pressure non-condensable mixture. The second water gas shift reaction the high pressure non-condensable mixture is heated and steam is added to produce second water gas shift effluent. The hydrogen recovery unit is selected from hydrogen pressure swing adsorption unit and/or additional hydrogen membrane unit. The pressure of the high pressure syngas stream is 15-100 bar. The high pressure syngas stream is heated at 200-450 degrees C. The solid fuel source is selected from coal, petcoke, and bio fuel. The second membrane stream is compressed to a pressure of 30-80 bar. The dew point of the compressed second membrane stream is reduced to a temperature that is suitable for cryogenic purification without causing the plugging of the processing unit due to water freezing. The pressure of the high pressure syngas stream is 30-80 bar. The steam is added to the high pressure syngas for the water gas shift reaction in the hydrogen membrane/water gas shift reactor. The process further involves removing the sulfur compounds present in the second membrane stream in sulfur recovery unit to form sweet second membrane stream prior to being introduced into the dehydration unit. The high pressure non-condensable mixture is heated and steam is added during the second water gas shift reaction to produce second water gas shift effluent. EXAMPLE - No suitable example given.
