    摘要: The invention concerns a process for producing carbon monoxide (CO) from carbon dioxide (CO2) in a solid oxide electrolysis cell (SOEC) or SOEC stack, wherein CO2 is led to the fuel side of the stack with an applied current and excess oxygen is transported to the oxygen side of the stack, optionally using air or nitrogen to flush the oxygen side, and wherein the product stream from the SOEC, containing CO mixed with CO2, is subjected to a separation process. The process further comprises heating the inlet gas on both the fuel side and the oxygen side by means of separate heating units, so as to supply heat to the SOEC, where the operation temperature of said heating units is at least equal to the operation temperature of the cell stack minus 50° C., preferably at least equal to the operation temperature of the cell stack.

    摘要: A method for removing hydrogen sulfide (H2S) from an acid gas comprises feeding the gas to a membrane separation unit, collecting the product gas from the membrane unit, heating the permeate stream to the necessary inlet temperature for catalytic oxidation of H2S and feeding the heated permeate stream to a catalytic oxidation unit, where H2S is oxidized to SO2. The heating of the permeate stream is accomplished by using a fraction of the feed gas to heat the permeate stream in a separate heater or by using a steam-fired heater. The method is especially suited for use on an off-shore facility.
