    摘要: A life-support system including a shelter, combined with equipment for sustaining a breathable atmosphere within the shelter. The breathable atmosphere is sustained by providing a supply of fresh air to the shelter, and removing carbon dioxide from the shelter. To provide the air supply, air containing a toxic agent is fed to a membrane separation unit. The membrane unit has a high selectivity to the permeation of oxygen over toxic agent and produces an oxygen-enriched permeate stream, while rejecting almost all of the toxic agent. The oxygen-enriched air is then passed through a unit containing a sorbent, such as activated carbon, to remove any remaining traces of toxic material before being fed to the shelter. The carbon dioxide content of the shelter air is kept below 1% either by sweeping the carbon dioxide away by maintaining a relatively high flow of air into and out of the shelter, or by withdrawing air from the shelter, treating it in a separate unit of equipment to remove carbon dioxide, and then returning the treated air to the shelter.

    摘要: Disclosed herein are combustion systems and power plants that incorporate sweep-based membrane separation units to remove carbon dioxide from combustion gases. In its most basic embodiment, the invention is a combustion system that includes three discrete units: a combustion unit, a carbon dioxide capture unit, and a sweep-based membrane separation unit. In a preferred embodiment, the invention is a power plant including a combustion unit, a power generation system, a carbon dioxide capture unit, and a sweep-based membrane separation unit. In both of these embodiments, the carbon dioxide capture unit and the sweep-based membrane separation unit are configured to be operated in parallel, by which we mean that each unit is adapted to receive exhaust gases from the combustion unit without such gases first passing through the other unit.

    摘要: A process for treating mixtures of organic components, including azeotropic mixtures. The process includes a gas- or liquid-phase membrane separation step in conjunction with a dephlegmation step to treat at least a portion of the permeate vapor from the pervaporation step. The process yields a membrane residue stream, a stream enriched in the more volatile component as the overhead stream from the dephlegmator and a condensate stream enriched in the less volatile component as a bottoms stream from the dephlegmator. Any of these may be the principal product of the process.

The apparatus includes a pervaporation unit and condenser, one or more tanks and a control system to direct liquid flows within the apparatus according to the chosen processing scheme. The apparatus and process can achieve separation performance comparable to a one-stage, two-stage, two-step or more complicated pervaporation system, including those in which two-phase permeates are produced.

    摘要: A refrigeration process including a refrigeration cycle, and refrigerant purge and recovery operations is disclosed. The refrigeration cycle may be a vapor compression cycle or an absorption cycle, for example. A purge stream is withdrawn from the refrigeration cycle and subjected to treatment by means of a membrane separation unit. The purge-stream treatment operation produces an essentially pure refrigerant stream, suitable for return to the refrigeration cycle, and an air stream, 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.
