Abstract
A pressure swing adsorption type hydrogen manufacturing apparatus includes a process control unit that controls operation of adsorption towers that generate a product gas by adsorbing, using adsorbents, adsorption target components other than hydrogen components from a source gas, in a state where an adsorption process, a pressure-equalization discharge process, a desorption process, and a pressure-restoration process are successively repeated. The process control unit is configured to control operation of the adsorption towers in such a manner that a prior pressure-equalization process is performed in an initial stage of a unit processing period, a subsequent pressure-equalization process is performed in a final stage of the unit processing period, a pressurization process of introducing a product gas to perform pressurization is performed, as the pressure-restoration process, subsequently to the prior pressure-equalization process, and the pressurization process is performed while overlapping with the subsequent pressure-equalization process.
