ABSTRACT:
A system and process is disclosed for eliminating paint solvents released during paint spraying operations into the circulated air including a liquid spray solvent stripper comprising a multistage absorber unit through which the exhaust air is passed, and a heating and cooling arrangement for regenerating the solvent absorber liquid. A heat exchanger recovering heat from an incinerator or oven exhaust vaporizes the solvent and the solvent is recovered by being passed over cooling coils in a condensing chamber. The exhaust air is treated with a water circulation system to remove paint solids, a proportion of the solvent vapors passing into solution with the treatment water. A solvent stripper is provided consisting of an arrangement for applying a vacuum to the water circulated from a paint solid removal unit, causing the solvent to be vaporized out of solution, with the vapors condensed by being passed over cooling coils in a condensing chamber. The air and water stripper condensing chambers are purged by a vacuum pump directing the uncondensed solvent vapors and non-condensables into the incinerator.
