چکیده
It has been more than a century since dry cleaning had its origin in Paris, France. Since that time, the dry cleaning process, whereby garments are cleaned in a nonaqueous solvent, has witnessed many refinements. Gasoline and carbon tetrachloride have been replaced as dry cleaning fluids by perchloroethylene (perc, and also known as tetrachloroethylene), Stoddard solvent (a petroleum distillate) and fluorocarbon 113. Soaring solvent prices coupled with forebodings of stricter solvent emission levels have steered dry cleaning equipment manufacturers along a course of closed-loop design and “building a tighter ship”. Although the economics clearly favour the new, more efficient and less polluting equipment lines for any dry cleaner about to set up shop, the economics of modernizing existing facilities are more complex. Even so, the potential for recouping lost solvent dollars and preventing pollution __ by simple low-cost housekeeping measures is large, and in many instances, virtually untapped. ~

متن کاملThe viability of professional wet cleaning as a pollution prevention alternative to perchloroethylene dry cleaning.
The vast majority of dry cleaners worldwide use the toxic chemical perchloroethylene (PCE), which is associated with a number of adverse health and environmental impacts. Professional wet cleaning was developed as a nontoxic alternative to PCE dry cleaning but has not been widely adopted as substitute technology. In the greater Los Angeles, CA, region, a demonstration project was set up to show...
متن کاملEvaluation of Glycol Ether as an Alternative to Perchloroethylene in Dry Cleaning
Perchloroethylene (PCE) is a highly utilized solvent in the dry cleaning industry because of its cleaning effectiveness and relatively low cost to consumers. According to the 2006 U.S. Census, approximately 28,000 dry cleaning operations used PCE as their principal cleaning agent. Widespread use of PCE is problematic because of its adverse impacts on human health and environmental quality. As P...
