A method for continuously removing volatile organic paint carriers from paint spray booths is disclosed. By the process described, an oil-in-water emulsion is used to contact oversprayed paint in the paint spray booth. The emulsion is then broken and the oil phase is distilled to recover volatile components. The non-volatile components of the oil phase and recovered water are then recombined to form an emulsion and recycled to the paint spray booth.

Paint spray booth emissions control process

A method for recovering oil from a waste oil emulsion or sludge where the waste oil emulsion is heated and chemicals are added to obtain oil-water resolution, which includes conducting bottle and beaker tests on waste oil emulsion samples to obtain a trend which depicts a drop in viscosity as a function of the type and dosage of chemical added, and apparatus for utilizing the waste oil emulsion viscosity trend in the operation of a waste oil cooker or recovery vessel to add type and dosage of chemicals.

Method and apparatus for recovering oil from waste oil emulsion

A method for continuously removing volatile organic solvent paint carriers from the atmosphere of paint spray booths is disclosed. By the process described, an oil-water emulsion is used to scrub volatile organic materials from the paint spray booth atmosphere. The emulsion is then broken and the oil phase is distilled to recover volatile components. The non-volatile components of the oil phase and recovered water are then recombined to form an emulsion and recycled to the paint spray booth.
