Description:
The report gives results of a study of the styrene removal efficiency o a pilot-scale version of the QUAD Chemtact scrubber, quantified by continuously measuring the total hydrocarbon (THC) content of spray both exhaust air entering and exiting the device with THC analyzers and, for some tests, by collecting EPA Method 18 samples (adsorption tube procedure) at the inlet and exit of the device. verage styrene removal efficiencies approached but were never > 55%. anufacturing processes that involve the spraying of styrene-based resins have been identified as a possible significant source of volatile organic compound emissions that may affect human health and contribute to the ozone nonattainment problem. ntil recently, no known cost-effective technology has been demonstrated to control such styrene emissions, and this short-term field evaluation was carried out to characterize the styrene removal efficiency of a pilot-scale version of the liquid chemical scrubbing process. his test was carried out at a facility (Eljer Plumbingware in Wilson, NC) that manufactures polyester bathtubs and shower stalls by spraying styrene-based resins onto molds in vented, open spray booths. ide stream of air, exhausted from one of the spray booths in the gel coating part or the process, was used for the test.
