Monoethylene glycol (MEG), also known as ethylene glycol (EG) or simply glycol, is a diol mostly employed for its production of polyester fibers and polyethylene terephthalate (PET) resins. It is also utilized in antifreeze programs and in pharmaceuticals and cosmetics. MEG is produced through the hydrolysis of ethylene oxide (EO), which is obtained via ethylene oxidation.
From the described process, MEG is produced via EO, which is fabricated in an integrated plant using Shell EO technology. An important characteristic of the procedure is the minimal production of diethylene glycol (DEG) and triethylene glycol (TEG), which occur as byproducts in other ethylene glycol production processes.
