20120241678 | METHOD FOR THE PRODUCTION OF HYDROGEN COMBINED WITH CARBON DIOXIDE CAPTURE - The present invention relates to a method for the combined production of hydrogen and carbon dioxide from a hydrocarbon mixture, in which the hydrocarbon mixture is reformed to produce a syngas which is cooled, then enriched with H2 and CO2, optionally dried, and treated in a PSA hydrogen purification unit to produce hydrogen, the PSA offgas being treated to capture the CO2 and to supply an offgas. This offgas is again treated to supply a stream enriched with H2 and CO2 which is returned to the PSA, where it constitutes a second feed distinct from the main feed. | 09-27-2012 |

20100193067 | Method and System for Optimized Filling of an Enclosure - An enclosure is filled with a filling gas according to the disclosed method. An enclosure is provided having an interior, a width, a height, a thickness, and fluid filling and exit holes fluidly communicating with the interior. Filling of the enclosure is commenced by directing a flow of the filling gas at a filling flow rate into the fluid filling hole. An oxygen concentration of gas exiting the fluid exit hole is sensed. The filling of the enclosure is stopped when the sensed oxygen concentration reaches a threshold concentration, wherein the threshold oxygen concentration and/or the filling flow rate are selected by a Decision Support Tool based upon the width, height, and/or the thickness. | 08-05-2010 |
20120291913 | METHOD AND SYSTEM FOR OPTIMIZED FILLING OF AN ENCLOSURE - An enclosure is filled with a filling gas according to the disclosed method. An enclosure is provided having an interior, a width, a height, a thickness, and fluid filling and exit holes fluidly communicating with the interior. Filling of the enclosure is commenced by directing a flow of the filling gas at a filling flow rate into the fluid filling hole. An oxygen concentration of gas exiting the fluid exit hole is sensed. The filling of the enclosure is stopped when the sensed oxygen concentration reaches a threshold concentration, wherein the threshold oxygen concentration and/or the filling flow rate are selected by a Decision Support Tool based upon the width, height, and/or the thickness. | 11-22-2012 |

20120067211 | Porous Hollow Fiber Supported Dense Membrane For Hydrogen Production, Separation, Or Purification - A dense hydrogen-permeable layer, such as palladium or palladium alloy, is deposited on a porous hollow fiber. A porous hollow fiber is defined as having an inner diameter of approximately 30 microns to approximately 1500 microns and an outer diameter of approximately 100 microns to approximately 2000 microns. This allows an order-of-magnitude increase in the surface per volume ratio in a hydrogen separation or purification module, or a membrane reformer or reactor. | 03-22-2012 |
