Glycols
At CHEM Group, glycols include a variety of compounds used across a wide range of industries in an even broader range of applications.
In general, the term "glycol" is most often applied to ethylene glycol that, in addition to being the smallest or simplest glycol molecule, is also the most common. In the United States alone, a little more than 8 billion pounds of ethylene glycol are produced each year; primarily for use in automotive antifreeze. As polyethylene terephthalate (PET), ethylene glycol is also used to produce resins that are important in the manufacture of plastic bottles, certain textiles, and polyester films.
Commercially, ethylene glycol is most typically produced by the liquid phase hydration of ethylene oxide that yields a mixture of about 90% ethylene glycol, 9% diethylene glycol, and 1% triethylene glycol.
In use, glycols become contaminated with water, hydrocarbons, urea, acids, heat stables salts, and certain metals. At CHEM Group these contaminants are removed to yield glycols that can be returned to service as reclaimed materials offering chemical and physical properties equivalent to their virgin counterparts, but at significant savings to the customer and the environment.
