  • Pressure swing adsorption process operation at turndown conditions
    Patent number: 6585804
    Abstract: A method for operating a pressure swing adsorption process at turndown conditions by adding selected steps to the normal design operation of the process. The selected steps include the extension of a make product/no feed step and the addition of idle steps at specific points in the process cycle during depressurization and repressurization. The average volumetric flow ratio of the pressurized feed gas to the final product gas during design operation and during turndown operation may be essentially equal. The average oxygen concentration in the final product gas during design operation and during turndown operation also may be essentially equal.
    Type: Grant
