    Patent number: 6352575
    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.
