ABSTRACT:
The permeable membrane assemblies disclosed in this application utilize the bi-leaf edge membrane concept and the lay-flat tubing connector concept presented in prior and pending patents for ionic systems. Herein these concepts are shown and claimed for their utility in transfer systems in general including selective transfer of gaseous fluids and liquid fluids whether ionic or not as well as for transfer of heat. As before the concepts offer advantages of simplicity and reliability and offer economical assembly in leak free equipment. Countercurrent flow of the fluids is obtained. Hydrogen separation from mixed gases is one application. The full range of dialysis and fluid to fluid extraction processes are prospective candidates for these design concepts.
