Abstract
Pressure swing adsorption separation of a gas mixture, containing a first component and also a second component which may be at low or trace concentrations, is performed to extract the second component from the gas mixture so that a first product stream containing the first component may be substantially purified with respect to the second component, while the second component is concentrated to a high degree in a second product stream. Gas mixtures containing three components may also be separated. The apparatus of the invention performs the separation within a single working space.
