| Abstract |
The purpose of this project was to investigate the capability of various engineering changes to an existing vapor degreaser to reduce solvent emissions to the atmosphere while remaining within the established Air Force exposure limits for 1,1,1-trichloroethane (TCA). A 1970 vintage vapor degreasing system had been converted from trichloroethylene to TCA and fitted with a lip vent exhaust system to decrease worker exposure. Solvent consumption with this configuration was two to three 55-gallon drums weekly, all presumed to be emmitted to the atmosphere via the lip vent. In sequence, various modifications to the degreaser and operating procedures were instituted to define their capability to reduce emissions and comply with exposure limit requirement. They include decrease and elimination of lip vent suction, a freeboard extension, add-on chiller, and a freeboard extension plus add-on chiller. |
