Abstract
An appartus for removing VOC from a plurality of remotely located sources of VOC contaminated gas streams includes a plurality of liquid absorbers, each located near and communicating with a source of a VOC contaminated gas stream, the liquid absorbers associating the VOC with a scrubbing liquid. A conduit is connected to each liquid absorber for conveying VOC laden scrubbing liquid from the liquid absorber to a separating apparatus in fluid communication with each of the conduits. The separating apparatus receives the VOC laden scrubbing liquid from the plurality of liquid absorbers and separates the VOC from the scrubbing liquid. A conduit recycles the scrubbing liquid from the separating apparatus to at least one of the plurality of liquid absorbers. A method for removing VOC from a plurality of remotely located sources of gas streams contaminated with VOC includes contacting each VOC contaminated gas stream with a scrubbing liquid close to the VOC containing gas stream source to associate the VOC with the scrubbing liquid. The VOC laden scrubbing liquid from the various sources is conveyed to a single separator and the VOC is separated from the scrubbing liquid at the separator.
