✦ Synopsis
Maqr s p r q painting facility operators have been under pressure to reduce the discharge of volatile organic compound (VOO emissions to the atmosphere. Some operators have been able to conuert their operations to lower VOC containing paints and coatings such as powder coating, waterborne coating, and radiation ciii*ed coatings. However, because of the functional requirements, for some painted surfaces, acceptable paints with low VOC content ma?! not be available. Consequently, these manujuctiirm ma-y require the continued use of the higher VOC content p i n t formulations.
iShe control of emissions from paint booths has been considered iiot economical& viable due to the cost oftreating the high uoltime ofpolluted air exhausted from these sources. Studies conducted b y EPA with uarious Department of Defense (DoD) services. houwer, haue demonstrated that the cost associated uith tpical spray booth control system can be significantly reduced through the use of sprav booth recirculation. Reductions ofexhaustflou~ rates of up to 90percent may be possible when using rt>ciiculation in properly designed and operated booths uiithour concen7.for the industrial hjgiene orfire safety issues @en mvntioned when discussing recirculating booths. Xbispaprrpresents the results of the design and demonstration program cfjiill scale recirculating spray paint booths installed aiid operated cit the C: S. Marine Corps (USMC), Marine Corp Logistics Bmes (MCLB) facilir?/ at Barstow, CA. It also summarizes ihe regu11itot-y and safety design issues of recirculation sprav booths.
