요약

A method and system for producing carbon dioxide (435), purified hydrogen (213) and electricity from a reformed process gas feed (205) using a solid oxide fuel cell SOFC (2), the method and system comprising the steps of: introducing the reformed process gas (205) into the solid oxide fuel cell (2); in the solid oxide fuel cell (2) converting hydrogen and carbon monoxide of the reformed process gas (205) in combination with oxygen into an anode off-gas (208) comprising steam, carbon dioxide and unconverted process gas; introducing the anode off-gas (208) into a high temperature water gas shift reactor (8);in the high temperature water-gas shift reactor (8), converting carbon monoxide and steam into carbon dioxide and hydrogen, introducing the gas (216) exiting the high temperature water-gas shift reactor (8) into a low temperature water-gas shift membrane reactor (4), in the low temperature water-gas shift membrane reactor (4), converting carbon monoxide and steam into carbon dioxide and hydrogen, whereby the low temperature water-gas shift membrane reactor (4) comprises a hydrogen pump (9) that produces purified hydrogen (213) on a permeate side (41), while removing hydrogen from a feed side (44).

A method for producing carbon dioxide (435), purified hydrogen (213) and electricity from a reformed process gas feed (205) using a solid oxide fuel cell SOFC (2), the method comprising the steps of: - introducing the reformed process gas (205) into an anode side (23) of the solid oxide fuel cell (2);- in the solid oxide fuel cell (2), introducing air (100) into a cathode side (21) of the solid oxide fuel cell (2) and in the anode side (23) converting hydrogen and carbon monoxide of the reformed process gas (205) in combination with oxygen into an anode off-gas (208) comprising steam, carbon dioxide and unconverted process gas;- introducing the anode off-gas (208) into a water gas shift reactor and a hydrogen pump (9);characterized in: - introducing the anode off-gas (208) into a high temperature water gas shift reactor (8);- in the high temperature water-gas shift reactor (8), converting carbon monoxide and steam into carbon dioxide and hydrogen,- introducing the gas (216) exiting the high temperature water-gas shift reactor (8) into a low temperature water-gas shift membrane reactor (4),- in the low temperature water-gas shift membrane reactor (4), converting carbon monoxide and steam into carbon dioxide and hydrogen, whereby the low temperature water-gas shift membrane reactor (4) comprises the hydrogen pump (9) that produces purified hydrogen (213) on a permeate side (41), while removing hydrogen from a feed side (44), so that the anode off-gas (208) is depleted of hydrogen and carbon monoxide to create a carbon dioxide rich gas stream (211) comprising mainly carbon dioxide (435) and steam, wherein the solid oxide fuel cell SOFC (2) is controlled to operate with a fuel utilization (FU) in the range of 0% to 90%, depending on a demanded amount of purified hydrogen (213) and carbon dioxide (435) to be produced.
