    Abstract: A filter device and technique are described which rely on absorption rather than adsorption for the removal of gas phase contaminants. A filter media (49) is composed of wicking fibers which are impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents. The wicking fibers may be connected to an external reservoir (37) which can be used to supply fresh absorbing fluid to the filter media giving them a potentially inexhaustible capacity. The filter media may be made from any of a variety of fibers which can rapidly transport a liquid phase by the nature of either their geometry or their chemical composition. Geometries may include multilobal cross-sectional configurations, porous hollow fibers, porous or striated fibers or tightly bundled microfibers, all of which exhibit the property of wicking fluid from an external source.

    Abstract: A unique filtration device (10) which continuously removes several gas phase contaminants from an airstream through the use of partially hollow wicking fibers (20) impregnated with a selected liquid which can capture the gas phase contaminants. The wicking fibers (20) are generally disposed parallel and are formed into a filter element (12) which extends from the airstream to be cleaned into another airstream which can strip and carry away the unwanted gas phase contaminants. The gas phase contaminants are conveyed to the stripping airstream by a concentration factor induced molecular migration. The airstream to be cleaned is directed through a compartment (16) across which the filter element (12) extends so the complete airflow is through filter element (12). Filter element (12) also extends into another compartment (18) through which the stripping airstream flows. The wicking fibers (20) include internal longitudinal cavities (22) each with a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected contaminant removing liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected liquid, with which they come into contact, through the internal cavities (22). The absorption liquid remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers, yet through the longitudinal openings (24) the liquid is in full communication with the airstream flowing past the fibers (20).

    Abstract translation: 一种独特的过滤装置（10），其通过使用浸渍有可捕获气相污染物的选定液体的部分中空芯吸纤维（20），从气流连续地去除多个气相污染物。 芯吸纤维（20）通常平行设置，并且形成为从要清洁的气流延伸到可以剥离和携带不需要的气相污染物的另一气流的过滤元件（12）。 通过浓度因子诱导的分子迁移将气相污染物输送到汽提气流。 要清洁的气流被引导通过隔室（16），过滤元件（12）延伸穿过该隔室（16），使得完整的气流通过过滤元件（12）。 过滤器元件（12）还延伸到另一个隔室（18）中，汽提气流通过该隔室（18）流动。 芯吸纤维（20）包括各自具有相对小的纵向延伸开口（24）的内部纵向空腔（22）。 芯吸纤维（20）通过毛细管作用填充所选择的污染物去除液体，通过该毛细管作用，各个芯吸纤维（20）通过内部空腔（22）快速地吸引与它们接触的选定液体。 吸收液体保持在芯吸纤维空腔（22）内，并且通常不进入芯吸纤维之间的空间，但是通过纵向开口（24），液体与流过纤维（20）的气流完全相通。
