摘要： A membrane separation process and system for removing a component from a fluid stream. An auxiliary membrane module or set of modules is installed across the second stage of a two-stage membrane separation system. The driving force for the auxiliary modules is provided by the pump or other driving unit for the first membrane stage. The auxiliary module or modules provides additional treatment of the residue stream from the second membrane stage, but are driven by the first stage driving unit. The invention is particularly useful in any membrane separation operation involving gas separation, vapor separation or pervaporation in which a two-stage system design is to be used, and where it is desirable to improve the efficiency of the two-stage system.

摘要： A process for treating gas streams containing a sterilant gas and a diluent gas, such as sterilizer exhaust streams. The process involves a sterilant removal step and a diluent removal step. The sterilant removal step can be absorption, catalytic oxidation or some other chemical reaction. The diluent removal step includes a membrane separation step, and may include a condensation step. The permselective membranes used for the membrane separation step are typically selective for the diluent gas over other gases in the stream. The process removes essentially all the sterilant present in the feed stream, and typically removes 90% or more of the diluent. The process is particularly useful for treating ethylene oxide/CFC-12 mixtures.

摘要： A composite membrane particularly useful for gas separation or pervaporation. The membrane has three layers: a microporous substrate, an intermediate sealing layer, and a top permselective layer. The permselective layer is made by interfacial polymerization directly on the sealing layer. The sealing layer prevents penetration of the interfacial polymerization reagents into the substrate pores during membrane preparation and provides a gutter layer in the finished membrane.

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 separation process for recovering organic components from liquid streams. The process is a combination of pervaporation and decantation. In cases where the liquid stream contains the organic to be separated in dissolved form, the pervaporation step is used to concentrate the organic to a point above the solubility limit, so that a two-phase permeate is formed and then decanted. In cases where the liquid stream is a two-phase mixture, the decantation step is performed first, to remove the organic product phase, and the residue from the decanter is then treated by pervaporation. The condensed permeate from the pervaporation unit is sufficiently concentrated in the organic component to be fed back to the decanter. The process can be tailored to produce only two streams: an essentially pure organic product stream suitable for reuse, and a residue stream for discharge or reuse.
