摘要： Pervaporation processes and apparatus with few moving parts. Ideally, only one pump (4) is used to provide essentially all of the motive power and driving force needed to operate pervaporation unit (9) and move the various fluids into and out of separator (6) and across the feed side of the pervaporation unit. The process is particularly useful for handling small streams with flow rates less than about 2,652 L/day (700 gpd). Specifically, the process can be used to treat waste streams from glycol dehydrator regeneration units.

摘要： A separation process for recovering organic components from liquid streams. The process is a combination of pervaporation and decantation. The liquid stream to be treated (501) contains at least two organic compounds. A first decantation step (502) is used to remove an organic product phase (503), and the residue (504) from the decanter is then treated by a pervaporation step (505). The pervaporation step (505) is used to concentrate the remaining organic to a point above the solubility limit, so that a permeate stream (507) that will phase separate is formed. The condensed permeate stream (509) is then passed to a second decantation step (510). The aqueous stream (511) from the second decanter is returned to the pervaporation step (505). A system for performing the above steps on a three component feed stream (501) is also disclosed. The system includes a first decanter (502), a pervaporation unit (505) and a second decanter (510).

摘要： A spiral-wound pervaporation module, incorporating membrane envelopes (2), within and between which are channels through which the feed and permeate streams flow. The feed and permeate channels are created by feed spacers (3) and permeate spacers (4). The module is unconventional in that the permeate spacer is tailored for optimum permeate flow throughput, based on the discovery that the total permeate flow throughput 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. The increase in throughput per unit membrane area obtained more than compensates for the loss in membrane area brought about by use of a thicker permeate spacer.

摘要： A process involving membrane-based gas separation and power generation, specifically for controlling carbon dioxide emissions from gas-fired power plants. The process includes a compression step, a combustion step, and an expansion/electricity generation step, as in traditional power plants. The process also includes a sweep-driven membrane separation step and a carbon dioxide removal or capture step. The carbon dioxide removal step is carried out on a portion of gas from the compression step.

摘要： Improved membranes and improved membrane 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.

摘要： A refrigeration process including a refrigeration cycle (1), and refrigerant purge and recovery operations is disclosed. The refrigeration cycle may be a vapor compression cycle (2) or an absorption cycle, for example. A purge stream (12) is withdrawn from the refrigeration cycle (1) and subjected to treatment by means of a membrane separation unit (16). The purge-stream treatment operation produces an essentially pure refrigerant stream (18), suitable for return to the refrigeration cycle, and an air stream (17), clean enough for direct discharge to the atmosphere. The process is applicable to most refrigerants, but is particularly useful in minimizing atmospheric emissions of chlorofluorocarbons, such as CFC-11 and CFC-12.
