Abstract
A method includes combusting a fuel stream in a combustion unit in the presence of a first oxygen enriched carbon dioxide stream received from an anode of an electrolyzer to generate a hot flue gas stream comprising carbon dioxide, steam, unconsumed oxygen, NOand SO, cooling the hot flue gas stream in a heat exchanger by supplying a water stream to the heat exchanger as a heat transfer medium to generate a cooled flue gas stream effluent, processing the cooled flue gas stream effluent in one or more separation units to generate a carbon dioxide rich gas stream and a carbon dioxide lean gas stream, and passing the carbon dioxide rich gas stream to the anode of the electrolyzer to generate a second oxygen enriched carbon dioxide stream for sending to the combustion unit.
