stream comprising the gas comp. H2, H2O vapor, CH4, CO & optionally N2 (a) In a steam reformer plant for H2 or NH3 generation, having a primary reformer, a sec. reformer & downstream thereof, a CO conversion stage, removing between the sec. reformer & CO conversion stage, a part gas stream of said synthesis gas stream discharged from the sec. reformer, which has a CO content of 2-20 mol. % & is a T 200-500C & pressure 15-50 bar (b) Cooling said part gas stream to T < 100C thereby condensing out the major part of steam contained in said part gas stream resulting in a raw synthesis gas stream (c) Guiding said remaining raw synthesis gas by way of multi-stage gas sepn plant in which said gas comp. H2, residual H2O, CH4, CO2, CO & optionally N2 are separated either individually or together from the CO (d) Compressing the gas comp. H2, CH4, & optionally N2 from the CO, which are separated from the CO by compressing said gas comp. to pressure which exceeds the pressure in said CO conversion stage & are recombined to form mixed gas stream (e) Heating said mixed gas stream to T 200-500C & supplying said mixed gas stream to said CO conversion stage of said steam reformer plant (f) Removing remaining pure CO fraction in a separate manner & optionally, supplying said remaining pure CO fraction to further processing |
