A new scrubbing process to remove low concentrations of VOC's from air streams has been conceived. The process uses liquid scrubbing media in which VOCs have high solubilities. The VOC-laden scrubbing liquid is regenerated by a membrane pervaporation system producing a clean stream of scrubbing liquid suitable for immediate recycling. The new scrubbing medium would enable a compact, small- volume flow scrubber to be used for many applications where this was not possible previously. The combined scrubbing/pervaporation process would produce a concen- trated VOC-containing product stream and a solvent-free air stream; no secondary waste streams are produced. Based on preliminary cost calculations, the process appears likely to be competitive with alternative technologies.
