A composition for treating oversprayed paints that contains an effective amount of alcohol esters and alcohol ester derivatives in water. The carbonyl compound is capable of dissolving paint while remaining non-reactive with water. The alcohol ester employed has the general formula: ##STR1## The alcohol ester derivative employed has the general formula: ##STR2## R' and R' are a substituted or unsubstituted linear alkyl group containing 1 to 8 carbon atoms, R and R'' are linear or branched alkyl groups containing 1 to 10 carbon atoms, and R and R'' are either identical or different alkyl functionalities.

Composition for the paint spray treatment using secondary alcohol esters

A composition for treating oversprayed paints that contains an effective amount of a carbonyl compound such as alcohol esters and condensation products of alcohol esters and carboxylic acid in water together with a suitable surfactant. The carbonyl compound is capable of dissolving paint while remaining non-reactive with water. The alcohol ester employed has the general formula: ##STR1## The alcohol ester derivative employed has the general formula: ##STR2## R' and R' are a substituted or unsubstituted linear alkyl group containing 1 to 8 carbon atoms, R and R'' are linear or branched alkyl groups containing 1 to 10 carbon atoms, and R and R'' are either identical or different alkyl functionalities.

A transportable processing unit for producing a pumpable, essentially homogeneous admixed material suitable for use as substitute fuel or for thermal destruction by incineration, the processing unit including a closed mixing vessel mounted on a movable base member the vessel adapted to receive feedstock material from an adjacent on site holding facility through at least one entry port and to receive intermediate process material through at least one inlet port and a process material exit port as well as a mixing device located in the vessel interior. The processing unit of the present invention also has a conduit for conveying process material away from said mixing vessel, which is connected to the mixing vessel exit port, and at least one particle sizing device mounted on the moveable base member which has an inlet in fluid communication with a second end of the process material conveying conduit and at least one diverter outlet which is in fluid communication with the intermediate process material inlet port of the mixing vessel. The moveable base is preferably a transportable member such as a tractor trailer or a transportation skid.

Transportable processing unit capable of receiving various chemical

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.

Process for reclamation and treatment of paint overspray treatment

A composition for treating oversprayed paints that contains an effective amount of a carbonyl compound such as alcohol esters and alcohol ester derivatives in water together with a suitable emulsifier. The carbonyl compound is capable of dissolving paint while remaining non-reactive with water. The alcohol ester employed has the general formula: ##STR1## The alcohol ester derivative employed has the general formula: ##STR2## R' and R' are a substituted or unsubstituted linear alkyl group containing 1 to 8 carbon atoms, R and R'' are linear or branched alkyl groups containing 1 to 10 carbon atoms, and R and R'' are either identical or different alkyl functionalities.

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.
