This is a feasibility study of a membrane gas-separation process                operated with the feed pressure cycled between two levels.  The                 process is suitable for separating gases with opposite diffusivity and          solubility selectivities.  The main driving force for separation in             this process is the solubility selectivity.  Thus, many gases with              close permeabilities can be separated by this process, but not by the           conventional constant-pressure process.  By proper cycling of the feed          pressure, the separations achievable by the conventional processes are          also enhanced.  Experiments on several polymer-gas mixture systems              will be performed.  Model simulations will accompany experiments.                                                                                               Success of the research would lead to new possibilities for membrane            separations which are not achievable by the conventional operation.
