| Abstract |
The report describes the characterization of air pollutant emissions from a polyurethane resin manufacturing plant. Samples were taken before and after the air pollution control device (scrubber). Analysis for toluene di-isocyanate (TDI) and amines was conducted both on site and on a delayed basis. The sampling train included an impinger for colorimetric measurement of TDI. Cryogenic traps and a tape sampler for TDI were also used for the scrubber inlet samples. The outlet sampling manifold consisted of evacuated bulbs in place of the cryogenic traps because of the high moisture content. TDI emissions were found to be maximum in the first part of the resin formation reaction. It appears there is no emissions hazard. The scrubber had negligible effect on the TDI emissions. |
