20090320519 | Recovery of Hydrofluoroalkanes - A mixture of air and one or more halogenated alkanes is directed to a gas separation membrane where it is separated into an oxygen, nitrogen, and moisture-enriched and halogenated alkane-depleted permeate and a halogenated alkane-enriched and oxygen, nitrogen, and moisture-depleted retentate. The retentate is directed to a cryogenic condenser where an amount of halogenated alkane is condensed therein. | 12-31-2009 |
20100077796 | Hybrid Membrane/Distillation Method and System for Removing Nitrogen from Methane - A hybrid gas separation membrane/cryogenic distillation method and system produces high purity gaseous methane from a gas mixture containing a majority of methane and a minority of nitrogen. | 04-01-2010 |
20100313750 | Method and System for Membrane-Based Gas Recovery - A fast gas is recovered from a feed gas containing a fast gas and at least one slow gas using a gas separation membrane. A controller may control a control valve associated with a partial recycle of a permeate gas from the membrane for combining with the feed gas. A controller may control a control valve associated with the backpressure of a residue gas from the membrane. | 12-16-2010 |

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 |
