摘要:
The invention relates to a membrane module for treating fluids in a substance-specific manner, wherein first and second membrane elements (1, 2) comprising one end facing towards a distributor area (8) and one end facing towards a collector area (9) and a cavity (10, 11) formed by the membrane wall, respectively, are located. The first membrane elements (1) are embedded with their ends in casting compounds (4, 5) in such a way that their cavities are open and open into the distributor area (8) and into the collector area (9). The second membrane elements (2) are also embedded in the casting compound (5) with the ends facing towards the collecting area (9) and open into the collector area with their cavity there; but are closed at the end facing towards the distributor area (8).
摘要:
A fluid separation assembly (10) having a fluid permeable membrane (38, 62) and a wire mesh membrane (18 and 28) adjacent the fluid permeable membrane (38 and 62), wherein the wire mesh membrane (18 and 28) supports the fluid permeable membrane (38 and 62) 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 (10) can be used in a module (85) to separate hydrogen from a gas mixture containing hydrogen.

A module (214 Fig. 5) for separating a product from a mixed stream comprises a mixed stream chamber having inlet and outlet means and defining a first flow path for the mixed stream, a purge/product stream chamber having inlet and outlet means and defining a second flow path for a purge/product stream, the second flow path having a substantially countercurrent direction to that of the first flow path, and a membrane located between the mixed stream chamber and the purge/product stream chamber, the membrane being selectively permeable to the product. There is also disclosed a fuel cell system comprising a burner module (210) for mixing and combusting a fuel and air mixture to produce hydrogen rich fuel stream; a hydrogen fuel cell (250) for producing power/energy using the hydrogen fuel produced by the burner module; a hydrogen purification module (214) between the burner module and the fuel cell for extracting hydrogen fuel from the burner module for use in the fuel cell and that uses a purge gas to enhance purification module performance; hydrogen storage means (254) for storing hydrogen fuel produced by the burner module and not immediately required by the fuel cell; and means for feeding stored hydrogen fuel from the storage means to the fuel cell when the hydrogen requirements of the fuel cell are greater than the amount of hydrogen produced in the burner module.
摘要:
A high temperature membrane reactor or gas purification apparatus (10) includes a housing (12) containing a gas heating chamber (20) and a gas extraction component, preferably one or more tubular membranes (22). A surrounding annulus (24) provides heat exchange and insulation by circulating a mixed gas flow about housing (12) and then injecting the mixed gas flow into housing (12) for extraction or reaction. Apparatus (10) further includes an outlet (34) for releasing raffinate including a flow controlling restriction (38). Heating is provided by conducting the raffinate from the gas extraction component (22) to heating chamber (20) wherein reaction with catalyst (42) generates heat. A preferred application is for extracting hydrogen from the mixed gas flow or for generating hydrogen, e.g., by reforming methanol, ethanol, or gasoline. These features, alone or in combination, provide better energy management, better flow management, and better safety than current designs.
