Abstract: A process for treating spent aqueous emulsion material formed from a non-volatile hydrocarbon organic portion having a paint solids content greater than about 10% by weight in which the spent emulsion is broken and the organic phase is admixed with sufficient amounts of a hydrocarbon solvent extractant to extract organic portions of the aqueous emulsion. The hydrocarbon solvent extractant and the organic portion/solvent extractant mixture can then be distilled to provide essentially pure hydrocarbon solvent extractant and the hydrocarbon organic portion of the emulsion essentially free from paint solids. The organic portion of the material can then be admixed with quantities of water to reform a reclaimed emulsion. Examples of the paint overspray treatment emulsion on which the process of the present invention is highly effective is one which contains a hydrocarbon such as an alcohol ester, an alcohol ester derivative or mixtures of the two in combination in its organic phase.

Abstract: A composition for treating oversprayed paints that contains an effective amount of an essentially non-volatile carbonyl compound, an effective amount of an ethoxylated alkyl phenol surfactant in water together with a suitable emulsifier. The carbonyl compound is capable of dissolving paint solids while remaining essentially insoluble in and non-reactive with water. The carbonyl compound can be an alcohol ester having the general formulae ##STR1## an alcohol ester derivative having the general formula: ##STR2## in which R' and R" are a substituted or unsubstituted linear alkyl groups containing 1 to 8 carbon atoms, and R and R"' are linear or branched alkyl groups containing 1 to 10 carbon atoms. The surfactant has an average ethylene oxide-to-nonyl phenol ratio between 4:1 and 8:1.

Abstract: A method for detackifying oversprayed paint solids in a paint spray booth utilizes an oil-in-water emulsion as the hydrophilic fluid for capturing and detackifying oversprayed paint, which emulsion contains a certain nonionic surfactant, which surfactant greatly improves detackification performance when the paint formulation being sprayed is a low VOC formulation, and particularly a two-component formulation. The nonionic surfactant is an ethoxylated C.sub.8-10 alkyl phenol having an HLB value of from about 4.5 to 15.5.

Abstract: A method for the removal of over-sprayed paint solids which comprises contacting the over-sprayed paint solids with an oil-in-water emulsion until the emulsion is loaded with at least 5 parts by weight of paint solids per 100 parts by weight of the hydrocarbon liquid of the emulsion.

Abstract: 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.

Abstract: 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.

Abstract: 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.
