TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method (M1) further involves preheating the air stream to produce preheated air stream, where the oxygen-containing stream preheats the air stream utilizing heat-exchanger. The cathode is at 750-850 degrees C and pressure of 1-20 (preferably 1-2) bar, and the anode is at 750-850 degrees C and pressure 1-20 (preferably 1-2) bar. The preparing step further involves removing hydrogen sulfide from the feed stream to produce scrubbed feed stream. The hydrogen sulfide is removed from the feed stream by a liquid oxidation method to form the scrubbed feed stream. The preparing step further involves removing hydrogen sulfide by scrubbing the feed stream utilizing liquid oxidation method to form scrubbed feed stream; polishing the scrubbed feed stream utilizing zinc oxide bed to produce polished feed stream; and mixing hydrogen and steam with the polished feed stream to produce enriched feed stream. The treating step involves separating condensable components from the syngas, where the condensable components comprise water, to produce dry syngas; compressing the dry syngas to produce pressurized syngas; heating the pressurized syngas to produce heated syngas; and splitting the heated syngas to produce syngas side-stream and main syngas stream. The method (M2) further involves combusting the light fuel gas stream to produce first combustion gas in burner; first feeding step, where the first combustion gas is fed to first heat-exchanger to heat the polished feed to produce second combustion gas and the heated feed stream; second feeding step, where the second combustion gas is fed second heat-exchanger to heat the pressurized air stream to produce third combustion gas and the heated air stream; a scrubbed feed stream heating step, where the third combustion gas is fed to third heat-exchanger to heat the scrubbed feed stream using the third combustion gas to produce fourth combustion gas and preheated scrubbed feed stream; and third feeding step, where the fourth combustion gas is fed to fourth heat-exchanger to heat the dry syngas to produce fifth combustion gas and the heated syngas; and electric power generating step that produces waste gas comprising carbon dioxide and electrical power; feeding portion of the electrical power to the solid oxide electrolytic cell (SOEC) power supply; carbon dioxide capture step that treats the waste gas to produce purified carbon dioxide stream, where the purified carbon dioxide stream is greater than 99.9 vol.% pure in carbon dioxide; and feeding the purified carbon dioxide stream to the preparing step. The converting step utilizes Fisher-Tropsch processing to produce the liquid fuels. The Fisher-Tropsch processing further involves producing steam stream; and combining the steam stream with the polished feed stream to produce an enriched feed stream. The carbon dioxide capture step is achieved by method that is selected from absorption, cryogenic processing, membrane separation, adsorption, and/or oxy-combustion. The carbon dioxide capture step is by absorption utilizing liquid amine. Preferred Components: The liquid amine is either Selexol (RTM: mixture of the dimethyl ethers of polyethylene glycol) or Rectisol (RTM: acid gas removal process). EXAMPLE - No suitable example given.
