Abstract
A fluid separation assembly having a fluid permeable membrane and a wire mesh membrane adjacent the fluid permeable membrane, wherein the wire mesh membrane supports the fluid permeable membrane and is coated with an intermetallic diffusion barrier. The barrier may be a thin film containing at least one of a nitride, oxide, boride, silicide, carbide and aluminide. Several fluid separation assemblies can be used in a module to separate hydrogen from a gas mixture containing hydrogen.
Claims37
A fluid separation assembly comprising:
- a. a permeate plate having a first surface, a second surface, a fluid outlet and fluid passageways extending from said first surface and said second surface to said fluid outlet;
- b. first and second wire mesh membrane supports adjacent said first surface and said second surface of said permeate plate, respectively, each of said first and second wire mesh membrane supports comprising a wire mesh having a coating that is an intermetallic diffusion bonding barrier and having an opening aligned with said fluid outlet of said permeate plate;
- and
- c. first and second fluid permeable membranes, said first fluid permeable membrane adjacent a surface of said first wire mesh membrane support opposite said permeate plate, said second fluid permeable membrane adjacent a surface of said second wire mesh membrane opposite said permeate plate, each of said first and second permeable membranes having an opening aligned with said fluid outlet.
