Title: FUEL GAS SUPPLY APPARATUS AND FUEL GAS SUPPLY METHOD
Abstract:
In order to provide a technique of reforming a heavy hydrocarbon gas and supplying a fuel gas containing methane gas at a high concentration, the present invention is provided with: a reforming device 10 including a gas generation part 11 for steam-reforming a heavy hydrocarbon gas desulfurized by a desulfurization device 20, using a reforming catalyst, so that the gas undergoes a decomposition reaction to decompose into methane, and thereby producing a methane-containing gas mixture, and a resynthesis part 12 for resynthesizing methane from carbon monoxide and hydrogen contained in the gas mixture using a catalyst; a supply path L1 for supplying a heavy hydrocarbon gas to the reforming device 10 through the desulfurization device 20; a heat exchange part for performing heat exchange between the gas mixture from the gas generation part 11 and a heavy hydrocarbon gas flowing through the supply path L1 before desulfurization, in the resynthesis part 12; a recirculation path L4 for feeding a portion of the gas mixture produced by the gas generation part 11 back to the supply path L1; and a fuel gas supply path L5 for supplying a fuel gas discharged from the resynthesis part 12 to a combustion apparatus (gas engine GE).
