Trichloroethylene (TCE) emissions reductions achieved by enclosing solvent spray degreasing operations.

摘要

Allied Signal Inc., Kansas City Division (KCD), produces precision electrical and mechanical parts at the US Department of Energy's Kansas City Plant (KCP). The KCD, in cooperation with the DOE and Sandia National Labs (SNL), has completed a goal to eliminate chlorinated hydrocarbons from production processes to the maximum extent practical. This has resulted in many cleaning operations converting from chlorinated hydrocarbon solvents, such as trichloroethylene (TCE), to other processes. Solvent spray cleaning operations which use TCE today do not have a practical alternative. KCP has implemented the use of enclosed ventilation booths. This reduces the amount of TCE emitted into the air by 71%. This report documents the use of the enclosed booth, cost of installation, and benefits of the booth.
