Abstract
A stack emission control system utilized to remove organic contaminants as water-soluble solids from air collected from the vicinity of a polyurethane foam line assembly prior to the exhaust of the air into the surrounding atmosphere is described. A conventional packed tower scrubber is utilized containing an inert material as packing and pH-adjusted water as the wash fluid. The pH-adjusted water serves to remove essentially all of the organic contaminants as water-soluble solids from the air prior to exhaust of the air. The contaminant water-soluble solids are then readily separable from the pH-adjusted water by post-treatment to allow for the separate disposal of the essentially contaminant-free water and the contaminant solids.
