Perchloroethylene perc

The solvent perchloroethylene (PERC) is used by approximately 90% of all EU dry cleaners today. ... [Pg.11]

The Vaportech technology has been used in the past to treat soils contaminated with chlorinated solvents such as perchloroethylene (PERC) and trichloroethylene (TCE) benzene, toluene, ethylbenzene, xylenes (BTEX) aromatics, ketones, gasoline-range and diesel-range organics, phenols, and other cyclic and noncyclic carbon compounds including ketones, naphtha, mineral spirits, and lacquer diluter.

Solvent processing was introduced by manufacturers to reduce water and effluent charges. The basic process is similar to dry-cleaning and now uses perchloroethylene (Perc) as the solvent medium rather than the traditional Stoddard solvent. During the process a small amount of water is added with the detergent system to assist in the removal of water-soluble contaminants. The system is totally enclosed and all the solvent is recovered by distillation. [Pg.395]

Perchloroethylene (PERC), Cl2C=CCl2 is commonly being used as a solvent for dry cleaning. It is now known that PERC contaminates ground water and is a suspected human carcinogen. [Pg.15]

The solvents that are mostly employed include volatile organic solvents (VOCs) like methylene chloride, chloroform, perchloroethylene (PERC) and carbon tetrachloride. Some VOCs like, isopropyl alcohols, xylenes, toluenes and ethylenes have been used as cleaning fluids because of their ability to dissolve oils, waxes and greases. Also, they readily evaporate from the items that they are being used to clean (VOCs readily evaporate or vaporise at room temperature). When VOCs come in contact with sun light and nitrogen oxides (by-products from the combustion of fossil fuels), these are transformed into ozone, nitric acid and partially oxidised organic compounds.

Chlorinated solvents (cleaning) Solvents containing carbon and chlorine, such as trichloroethylene (TCE), methylene chloride (MEC), Perchloroethylene (PERC), and 1,1,1 trichloroethane (TCA). Very effective solvents but regulated because of health and environmental concerns. Example Carbon tetrachloride (CCI4), a fully chlorinated solvent. See also Chlorofluorocarbon (CFC) solvents Hydrochlorofluorocarbon (HCFC) solvents. [Pg.580]
