A method of removing low vapor pressure liquid contaminants, including polychlorinated biphenyls, from flowing gas streams. The gas stream is directed through a series of distinct gas-liquid separation stages, with each stage constructed to physically remove successively smaller concentrations of liquid contaminants from the stream. Within each stage, the contaminants are coalesced, then collected in a suitable solvent, present in sufficient quantity to preclude re-entrance of the contaminant into the flow system.
