Where does Tetrachloroethylene come from?
Much of the tetrachloroethylene released into the air comes from the dry cleaning industry. Some Tetrachloroethylene may be released from dry-cleaned or consumer products.
How is Trichloroethylene made?
The current method of manufacture is from ethylene. Trichloroethylene can be produced using oxichlorination or noncatalytic chlorination of ethylene dichloride or other C2-chlorinated hydrocarbons. Another method involves using catalytic hydrogenation of tetrachloroethylene (ECSA, 2012).
What is perc used for?
Perchloroethylene, also known as perc, is a colorless, nonflammable liquid solvent with a sweet, ether-like odor. It is primarily used in industrial settings and also for dry-cleaning fabrics and degreasing metals.
What is used for degreasing metals?
Strong alkaline solutions are used for degreasing steel and stainless steel. The salt mixture serves as a so-called builder substance. They therefore form the basis or grid of the solution. They are inorganic dirt carriers and saponify the grease.
What is an alternative to methane TCE?
TCE is a relatively common carrier used in solvent-based paints. Alternatives include lower solvent content paints containing other solvents, or switching to aqueous-based latex paints. In addition, depending on the application, 100% solids paint processes such as powder coating may be appropriate alternatives.
