  • PSA separation-purification system and process integrated with water gas shift reaction process
    Patent number: 11465094
    Abstract: Disclosed herein are a pressure swing adsorption (PSA) separation-purification system and process integrated with a water gas shift reaction process. According to the invention, the adsorption/desorption heat of a PSA separation-purification device is controlled using a reaction effluent and a refrigerant of a water gas shift reaction process without using additional components such as a heat exchanger or a heating means or without changing the structure of a PSA separation-purification device, thus achieving the best separation-purification performance of the PSA separation-purification device.
