摘要： RO membranes using chlorinated water as a feed stream maybe protected from damage by the chlorine with a protective layer including reactive nitrogen which forms chloromines on the surface of the membrane that reduce chlorine penetration. This protective layer also provides substantial anti-fouling capabilities, whether used with a chlorinated or unchlorinated feed stream because the chloramines are anti-bacterial. Although chlorine is lost in use, the anti-fouling layer or coating can be recharged with additional chlorine without damaging the discrimination layer. The anti-fouling layer or coating may be advantageously used with Thin film composite, TFC, membranes for use in forward and reverse osmosis may include nanoparticles, monohydrolyzed and/or di-hydrolyzed TMC, and/or alkaline earth alkaline metal complexes or other additives.

摘要： Gas separation processes are provided for separating dehydrogenation reaction products from a raw gas stream to recover hydrocarbons, specifically olefins, such as propylene and iso-butene, as well as unreacted feedstock. The processes employ a sequence of partial condensation steps, interspersed with membrane separation steps to raise the hydrocarbon dewpoint of the uncondensed gas, thereby avoiding the use of low-temperature or cryogenic conditions.

摘要： A gas separation process that utilizes ejector recycle with a membrane separation step in combination with a second separation step. The second separation step may be a second membrane separation, or may involve a different type of separation process. At least a portion of the non-product (i.e. residue) stream withdrawn from the second separation step is directed back to the ejector to form a processing loop. The ejector drives the gas flow in the loop and recycles the non-product stream to the first separation step.

摘要： Disclosed herein is a methanol production process that includes at least two membrane separation steps. Using the process of the invention, the efficiency of methanol production from syngas is increased by reducing the compression requirements of the process and/or improving the methanol product yield. As an additional advantage, the first membrane separation step generates a hydrogen-rich stream which can be sent for other uses. An additional benefit is that the process of the invention may debottleneck existing methanol plants if more syngas or carbon dioxide is available, allowing for feed of imported carbon dioxide into the synthesis loop. This is a way of sequestering carbon dioxide.
