Is the Exporter and Supplier of Monoethylene Glycol(MEG 99.8%) , Diethylene Glycol(DEG 99.8%) and Triethylene Glycol(TEG 97%) for different industries like Anifreeze, Polyurethane, Polyester and PET
We provide and export Monoethylene Glycol (MEG) , Diethylene Glycol (DEG) and Triethylene Glycol (TEG) from Iran to more than 15 countries. Our main purpose is to supply the best quality in the best packings in the shortest time.
Monoethylene glycol (MEG) is a strategical product which is produced in Iran because of plenty of petrochemical resources and is used in different industries like anti freeze , PET , Polyurethane, Polyester.
Diethylene glycol is a another strategical product which is produced in Iran and is used in different industries like Break oil, Gas Industry , anti freeze.
Triethylene glycol also is produced in Iran and is used in different industries like anti freeze, oil and gas industries.
Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation:
C2H4O + H2O → HO−CH2CH2−OH
This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures. The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water. Under these conditions, ethylene glycol yields of 90% can be achieved. The major byproducts are the oligomers diethylene glycol, triethylene glycol, and tetraethylene glycol. The separation of these oligomers and water is energy-intensive. About 6.7 million tonnes are produced annually.
A higher selectivity is achieved by use of Shell‘s OMEGA process. In the OMEGA process, the ethylene oxide is first converted with carbon dioxide (CO2) to ethylene carbonate. This ring is then hydrolyzed with a base catalyst in a second step to produce monoethylene glycol in 98% selectivity. The carbon dioxide is released in this step again and can be fed back into the process circuit. The carbon dioxide comes in part from the ethylene oxide production, where a part of the ethylene is completely oxidized.
