摘要： 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.

摘要： A process for recovering quantities of carbonyl compound material from spent solvent-in-water emulsions derived from paint overspray treatment and capture systems in which the spent solvent-in-water emulsion is removed from the paint overspray treatment and capture system and fed into a reaction vessel. The reaction vessel employed includes an outer housing defining a reaction chamber and a plurality of mixing blades movably positioned in the reaction chamber. The surface area of the mixing blades are maintained at a temperature sufficient to generate volatilized carbonyl compound. The interior of the reaction vessel is maintained under a vacuum. The spent solvent-in-water emulsion is processed in the reaction vessel for an interval sufficient to generate volatilized carbonyl compound. The generated volatilized carbonyl compound material is removed from the reaction vessel for recycle and reuse and the residual solid material remaining in the reaction vessel after generation of the volatilized carbonyl compound material is removed. The spent solvent-in-water emulsion which can be treated by the solvent recovery process of the present invention contains carbonyl compounds selected from the group consisting of secondary alcohol esters, secondary alcohol ester derivatives, and mixtures thereof and has a boiling point of at least 150.degree. C., a vapor pressure between about 0.5 Torr at 20.degree. C. The spent solvent-in-water emulsion processed by the carbonyl recovery method can either be previously dewatered to produce a spent solvent-in-water emulsion material with little or no water remaining or can be processed with most or all of the water portion of the emulsion present. In such instances, the water portion may be con-generated with the carbonyl compound.

摘要： A perturbed feedback control system for a process. Inputs to the process include a feed stream and a manipulated variable. The manipulated variable is controlled by a feedback controller. Measurements of a parameter measured "downstream" of the process are taken periodically and fed back to the controller. The feedback controller generates a control response on the basis of a comparison of the two most recent values of the downstream parameter. The comparison is made by calculating a perturbed set point which includes the values of the downstream parameter taken at the two most recent sampling periods. In a specific embodiment, the perturbed set point also includes measurements of the most recent and preceding values of the manipulated variable. A control response is applied to the manipulated variable by the feedback controller based on the value of the perturbed set point. The control system has been applied to optimize the feed rate of chemicals for sludge dewatering on a twin belt filter press.
