A composition and method of treating paint spray booth water to detackify organic solvent based paint particles. The composition comprises a melamine polymer obtained from the reaction of melamine, aldehyde and an amine selected from the group consisting of dicyandiamide and glycine. These melamine polymers may be used in combination with a polyacrylamide, which combination exhibits surprising and unexpected effects when used to detackify organic solvent paint particles.

Paint spray booth organic detackification treatment

The present invention is directed to a novel method for analyzing aqueous systems to simultaneously quantify the concentrations of multiple active or inactive treating components which may be contained therein. The method comprises determining the absorbance or emission spectrum of the components in the aqueous system over the wavelength range of from 200 to 2500 nm, and then applying chemometrics algorithms to extract and analyze features in the spectrum that are specific to the qualitative and quantitative concentrations from the specific components to simultaneously determine the concentrations of the components.

Spectrophotometric monitoring of multiple water treatment performance

A liquid borate is added to sulfur trioxide-containing combustion gases at a temperature of from about 250.degree. to about 1000.degree. F. in a boiler or other furnace system. The borate neutralizes sulfuric acid in the gases and inhibits sulfuric acid corrosion and deposition on metal surfaces of the system that contact the gases. An organic deposit modifying agent such as sorbitol and an additional acid neutralizing agent such as an alkali metal hydroxide, aluminate, or silicate may also be added to the combustion gases.

Method of inhibiting cold end corrosion in boilers

Uncalcined vermiculite is injected into the coal fired furnace, at 3000.degree.-1200.degree. F., thereby facilitating removal of deposits that accumulate on line within the furnace.
