Minimizing pollution in cleaning and degreasing operations. Final report, 14 February 1989-10 October 1991
The objective of this study was to examine approaches to decreasing rates of loss by evaporation and extending the useful lifetime of metal-cleaning solvents in service as means to decrease the generation of pollutant emissions and residues from Air Force cleaning and degreasing operations. An earlier study correlated properties of cleaning solvents with cleaning performance. This report includes data from an experimental study in which the same properties are measured in solvents that had been removed from service for recovery. Also included is an evaluation of the operation and maintenance of several degreasers in operation at Tinker AFB, together with specific suggestions to decrease the rate of evaporative loss. In the test, a measured volume of spent TCA was delivered into the sump of a recirculating filtration system. During recirculation, water content and color intensity decreased with reasonable consistency, while the acid acceptance value (AAV) remained essentially constant.
