Abstract:
1. A hydrogen production apparatus, which is provided in a power generation plant comprising a boiler and a steam turbine that is driven by a high-temperature steam produced in the boiler, and which produces steam for supply to other apparatus within the power generation plant, the hydrogen production apparatus comprising: a humidifier, which is supplied with a process fluid containing carbon monoxide, wherein the humidifier is operable to mix the process fluid with a steam; a reactor, which reacts a humidified process fluid output from the humidifier in presence of a catalyst, thereby converting the carbon monoxide within the process fluid into carbon dioxide; a first pipe through which a high-temperature process fluid flows following reaction in the reactor; a second pipe for supplying a makeup water; at least one first heat exchanger disposed at one location of one or more locations where the first pipe and the second pipe cross each other; and a third pipe for supplying steam generated by heat exchange in the first heat exchanger to another apparatus; a discharge passage through which a portion of excess moisture within the humidifier is released externally; a second heat exchanger provided at a location where the second pipe and the discharge passage cross each other; and a gas-liquid separator that is supplied with makeup water that has completed heat exchange within the first heat exchanger and the second heat exchanger, wherein the third pipe is connected to a gas phase portion of the gas-liquid separator, and steam separated by the gas-liquid separator is supplied to the other apparatus.
