Vapor control system for vapor degreasing/defluxing equipment

摘要: An improved vapor degreaser characterized by a deep freeboard zone (i.e., to width ratio of 1.0 2.3) containing three-stage condenser/heat exchanger configuration comprising: water-cooled lower primary operating above 32° F. effect condensation the bulk generated boiling sump and combination an intermediate above, but preferably overlapping, dehumidifying third position just below top lip degreaser, both at temperature (preferably +10° -30° F.) reduction in concentration gradient that controls rate diffusion through zone. The is particularly useful reducing losses when using low solvents.
