摘要： The invention is a process involving membrane-based gas separation for separating and recovering carbon dioxide emissions from combustion processes in partially concentrated form, and then transporting the carbon dioxide and using or storing it in a confined manner without concentrating it to high purity. The process of the invention involves building up the concentration of carbon dioxide in a gas flow loop between the combustion step and a membrane separation step. A portion of the carbon dioxide-enriched gas can then be withdrawn from this loop and transported, without the need to liquefy the gas or otherwise create a high-purity stream, to a destination where it is used or confined, preferably in an environmentally benign manner.
摘要翻译：本发明是一种涉及膜基气体分离的方法，用于从部分浓缩形式的燃烧过程中分离和回收二氧化碳排放，然后运输二氧化碳并以密闭方式使用或储存，而不将其浓缩至高纯度。本发明的方法涉及在燃烧步骤和膜分离步骤之间建立气流回路中二氧化碳的浓度。然后可以将一部分富含二氧化碳的气体从该回路中排出并运输，而不需要将气体液化或以其它方式产生高纯度物流到其使用或限制的目的地，优选地以环境友好方式。

摘要： A gas separation process for treating flue gases from combustion processes, and combustion processes including such gas separation. The invention involves routing a first portion of the flue gas stream to be treated to an absorption-based carbon dioxide capture step, while simultaneously flowing a second portion of the flue gas 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： 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 a gas mixture containing at least an organic compound gas or vapor and a second gas, such as natural gas, refinery off-gas or air. The process uses two sequential membrane separation steps, one using membrane selective for the organic compound over the second gas, the other selective for the second gas over the organic vapor. The second-gas-selective membranes use a selective layer made from a polymer having repeating units of a fluorinated polymer, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment, and good recovery after exposure to liquid aromatic hydrocarbons. The membrane steps can be combined in either order.

摘要： A process for treating a gas stream to remove or recover a condensable component. The process involves a condensation step and a membrane concentration step. The condensation step may be followed by the membrane step, or vice versa. The process can be designed to yield only two product streams: one, the condensed liquid, ready for use, reuse or discard, and two, a residue gas stream which im most cases will be clean enough for direct discharge or reuse. This result is achieved by recycling other streams within the process. Recovery of 90% or more of the condensable component can be achieved. The process offers substantial energy savings compared with condensation alone.
摘要翻译：一种处理气流以除去或回收可冷凝组分的方法。该方法包括缩合步骤和膜浓缩步骤。缩合步骤之后可以是膜步骤，反之亦然。该方法可以设计成仅产生两种产物流：一种是冷凝液体，即可使用，再利用或丢弃，二是大多数情况下的残留气流将足够清洁以直接排放或再利用。这个结果是通过回收过程中的其他流来实现的。可以实现90％以上的可冷凝成分的回收。与单独冷凝相比，该方法提供了显着的节能。

摘要： A membrane process and system for removing condensable vapors from gas streams is disclosed. The process includes a membrane separation step and a condensation or other recovery step. An auxiliary membrane module or set of modules is installed across the pump and condenser on the downstream side of the main membrane unit. This module takes as its feed the vent gas from the condenser, and returns a vapor-enriched stream upstream of the pump and condenser. The module can be sized to produce a discharge stream containing the vapor 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 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.
