Description:
The report describes the development of safe and cost effective strategies for controlling volatile organic compound (voc) emissions from Air Force painting facilities. A series of sampling and analysis tests were conducted to measure hazardous constituent compound concentrations in a typical crossdraft Air Force paint booth during painting; pollutant emission rates were simultaneously measured. Particulate, isocyanate and VOC emission rates were measured in the booth exhaust; concentration profiles of these constituents within the booth were determined during painting. Test results indicate that significant pollutant stratification occurs in the crossdraft booth during painting. Based on these results, a cost effective means of controlling VOC emissions was developed in which the exhaust from the zone of the booth having the highest VOC concentrations is passed to an emission control device. The remainder is vented to the outdoors. This flow reduction/control technology requires the installation of a split- flow ventilation system which separates the exhaust from the high concentration zone from the remainder of the exhaust. An alternative cost-effective flow reduction/VOC control technology involving exhaust flow recirculation was proposed. Finally, the possibility of combining these two ventilation systems (split-flow and recirculation) was explored.
