Description:
High-volume, low-VOC-concentration air streams are produced by a broad range of industries. The most widely used conventional treatment technology is carbon adsorption. However, carbon adsorption produces dilute aqueous waste streams as a secondary waste, is difficult to adapt to particulate-containing streams, and is too expensive to be applied by some industries. Wet scrubbing the air is a low-cost alternative technology, but it is generally limited to scrubbing with water because of the expense and difficulty of regenerating non-aqueous scrubbing liquids. The technology proposed here uses a low volatility organic scrubbing liquid to remove VOCs from the dilute air stream. The liquid is regenerated by a combined stripper/membrane vapor separation unit. In Phase I, the technical and economic feasibility of the scrubbing liquid regeneration step will be evaluated in laboratory tests with an existing stripper/pilot-scale membrane system. In Phase II, a scrubber will be added to the system for evaluation of the complete process.Supplemental Keywords:
