摘要： A process for removing organic compounds from water is disclosed. The process involves gas stripping followed by membrane separation treatment of the stripping gas. The stripping step can be carried out using one or multiple gas strippers and using air or any other gas as stripping gas. The membrane separation step can be carried out using a single-stage membrane unit or a multistage unit. Apparatus for carrying out the process is also disclosed. The process is particularly suited for treatment of contaminated groundwater or industrial wastewater.

摘要： A process for treating a gas stream to remove or recover a condensable component. The process involves a condensation step followed by a membrane concentration step. The process is useful in treating raw gas streams containing low concentrations of the condensable component, in treating small-volume raw gas streams, as an alternative to processes that require multistage membrane separation systems, in treating raw gas streams that have the potential to form explosive mixtures, or in situations where the treated gas stream composition must meet narrow target specifications.

摘要： A pervaporation process and system for removing a component from a liquid stream. The process includes a pervaporation separation step and a recovery step. An auxiliary membrane module or set of modules is installed across a condenser and/or recovery unit on the downstream side of the main pervaporation unit. This module takes as its feed a stream from the recovery unit and returns a component-enriched stream to the inlet of the condenser or recovery unit. The module can be sized to produce a discharge stream containing the component in about the same concentration as the feed to be treated. This discharge stream can then be mixed with the feed without adverse effect on the efficiency of the system.

摘要： A spiral-wound pervaporation module, designed to achieve optimum permeate flow throughput. The module is of conventional design and construction, in that it incorporates membrane envelopes, within and between which are channels through which the feed and permeate streams flow. The feed and permeate channels are created by spacers on the feed and permeate sides of the membrane layers. The module is unconventional in that the permeate spacer is tailored for optimum permeate flow throughput. The tailoring is based on the discovery that the total permeate flow throughput from a module passes through a maximum as the resistance to vapor transport of the permeate spacer material is progressively decreased. The resistance to vapor transport along the permeate channel is kept below a value at which it has a significant adverse effect on the membrane flux and the membrane separation properties, yet at the same time the total module throughput is within an optimum range.When modules in accordance with the invention are made, the increase in throughput per unit membrane area that is obtained more than compensates for the loss in membrane area brought about as a result of the use of a thicker permeate spacer. The modules are particularly advantageous for containing high-flux, high-separation membranes, and for low-pressure pervaporization processes.
摘要翻译： 螺旋缠绕渗透蒸发模块，旨在实现最佳的渗透流量。 该模块具有常规的设计和构造，因为它包含膜包膜，其内部和之间是进料和渗透物流通过的通道。 进料和渗透通道由隔膜在膜层的进料和渗透侧产生。 该模块是非常规的，因为渗透物间隔物适合于最佳的渗透流量。 定制是基于以下发现：随着渗透物间隔物材料的蒸汽输送的阻力逐渐降低，来自模块的总渗透流量通过最大值。 沿着渗透通道的对蒸汽输送的阻力保持在低于对膜通量和膜分离性能具有显着不利影响的值，同时总模块通量处于最佳范围内。 当制造根据本发明的模块时，获得的每单位膜面积的通过量的增加大于补偿由于使用较厚的渗透物间隔物而导致的膜面积的损失。 这些模块对于含有高通量，高分离膜和用于低压蒸发过程是特别有利的。

摘要： A process for removing an undesirable vapor from a pump exhaust by a membrane separation process. The process takes advantage of the pressure difference between the inlet and outlet sides of the pump 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.

摘要： A fluid treating apparatus has a plurality of chambers arranged in a stack along the apparatus axis; inlet and outlet ports in end plates as well as a central channel for introducing fluid into and removing fluid from the apparatus; and a plurality of fluid-impervious diaphragms situated in a spaced relationship in the chambers in an orientation generally perpendicular to the axis. The fluid is guided along the diaphragms generally radially inwardly. The apparatus further has a plurality of support frames arranged in a stack along the axis. Each support frame includes an inner ring spacedly surrounded by an outer ring. The radially inner face of the outer ring and the radially outer face of the inner ring of each support frame together define radially outer and radially inner boundaries, respectively, of the chambers. The radially outer faces of the outer rings together form an outer wall face of the apparatus, and the radially inner faces of the inner rings surround the central channel. Each outer ring has a supporting face engaging a radially outer marginal surface portion of an adjoining diaphragm, and each diaphragm has a central aperture in axial alignment with each inner ring and a passage at a radially outer part for allowing flow of fluid axially through each diaphragm.
