摘要： A fractionation process for treating a gas stream containing organic vapor in a concentration technically or economically difficult to treat by standard waste control methods. Typically this concentration will be about 0.1-10 % organic vapor. The process involves running the stream through a membrane system containing one or more membranes selectively permeable to the organic vapor component of the gas stream. The fractionation produces two streams: a product residue stream containing the organic vapor in a concentration less than about 0.5 % and a product permeate stream highly enriched in organic vapor content. Both residue and permeate streams are then suitable for treatment by conventional separations or waste control technologies. The low concentration residue stream might be passed to carbon adsorption beds, for example, and the high concentration permeate stream might be subjected to condensation or incineration.

摘要： A gas separation process for treating flue gases from combustion processes, and combustion processes including such gas separation. The invention involves flowing the flue gas stream to be treated across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, then passing the permeate/sweep gas to the combustor.

摘要： Improved processes for treating gas streams containing hydrogen sulfide, carbon dioxide, water vapor, and methane, particularly natural gas streams. The processes rely on the availability of two membrane types, one of which has a hydrogen sulfide/methane selectivity of at least about 40 when measured with multicomponent gas mixtures at high pressure. Based on the different permeation properties of the two membrane types, optimized separation processes can be designed. The membrane separation is combined with non-membrane treatment of the residue and/or permeate streams.

摘要： Removal of organic compounds from a water stream (3) involves gas stripping in gas stripper (1), followed by membrane separation of the stripping gas containing the organic compound (5) in membrane separator (2). Stripping can be carried out using one or multiple gas strippers and using air or any other gas as stripping gas (8). The membrane separator (2) can be a single-stage membrane unit or a multistage unit. The removal of organic compounds is particularly suited for treatment of contaminated groundwater or industrial wastewater.

摘要： Processes for removing water from organic compounds, especially polar compounds such as alcohols. The processes include a membrane-based dehydration step, using a membrane that has a dioxole-based polymer selective layer or the like and a hydrophilic selective layer, and can operate even when the stream to be treated has a high water content, such as 10wt% or more. The processes are particularly useful for dehydrating ethanol.

摘要： A membrane separation process (1) for treating a gas stream (3) containing methane and nitrogen, for example, natural gas. The separation process works by preferentially permeating methane (5) and rejecting nitrogen (4). We have found that the process is able to meet natural gas pipeline specifications for nitrogen, with acceptably small methane loss, so long as the membrane (2) can exhibit a methane/nitrogen selectivity of about 4, 5 or more. This selectivity can be achieved with some rubbery and super-glassy membranes at low temperatures.

The processes rely on th availability of two membrane of two membrane types, one of which has a high hydrogen sulfide/methane selectivity and a high water vapor/methane selectivity, when measured with multicomponent gas mixtures at high pressures.

摘要： A process for removing an undesirable vapor from a pump exhaust (5) by means of a membrane separation process (6). The process takes advantage of the pressure difference between the inlet (2) and outlet (3) sides of the pump (1) to provide the driving force for membrane permeation. The process of the invention can reduce the emission of pollutants or impurities from pumps to a very low level, such as 10 % or less of its previous value, with little extra expenditure of energy.
