Method and system for producing carbon dioxide, purified hydrogen and electricity from a reformed process gas feed

A system for producing carbon dioxide, purified hydrogen and electricity from a reformed process gas feed, the system comprising a solid oxide fuel cell SOFC,

• wherein the solid oxide fuel cell is fluidly connected with the reformed process gas feed for converting the reformed process gas in combination with oxygen into an anode off-gas comprising steam, carbon dioxide and unconverted process gas;
• wherein the system further comprising:
• a high temperature water-gas shift reactor, and a low temperature water-gas shift membrane reactor comprising a permeate side, a feed side, and an electrochemical pump there between,
• wherein the high temperature water-gas shift reactor is fluidly connected with the solid oxide fuel cell for receiving the anode off-gas, and for converting carbon monoxide and steam into carbon dioxide and hydrogen,
• wherein the feed side of the low temperature water-gas shift membrane reactor is fluidly connected with the high temperature water gas shift reactor for receiving the gas exiting the high temperature water-gas shift reactor, and for converting carbon monoxide and steam into carbon dioxide and hydrogen, and for separating the hydrogen by the electrochemical pump to create a purified hydrogen on the permeate side, so that the anode off-gas is depleted of hydrogen and carbon monoxide to create a carbon dioxide rich gas stream comprising mainly carbon dioxide and steam.
