It is the most common and economical means of water removal from these streams. Process History Ethylene glycol was first prepared by Wurtz in 1859 by the hy-drolysis of ethylene glycol diacetate but was not of commercial in-terest until World War I, when it was used in Germany as a sub- stitute for glycerol in explosives production [Curme and Johnston, 1952]. Dry glycol flows down the tower from the top, from tray to tray or through packing material. * Ethylene Glycol from Hydration of the Ethylene Oxide : Material required : Consider that the ethylene oxide required is also produced In the same plant.

A flow of recirculating water in the ethylene glycol unit of Shazand Petrochemical Company with a discharge of about 20m 3 /hr enters the treatment section, where 24 samples were randomly selected during different days of a year from the water going into the beds and coming out of their output to measure the amounts of the bed input and output aldehydes, MEG and ultra violet (U.V). Diethylene glycol (DEG) and triethylene glycol (TEG) are obtained as coproducts in the manufacture of MEG from ethylene oxide in some processes. The modern ethylene oxide/ethylene glycols plants are highly integrated units where ethylene oxide from the ethylene oxide reaction system can be recovered as glycols with a co-product of purified ethylene oxide if desired. And the other is the DMO(dimethyl oxalate) Route newly emerged in China these years, starting from syngas. The makeup raw material flows accounting for the recycle streams in the process are 237,000 MT fuel-grade ethanol per year, 81,000 MT oxygen per year, and 26,000 MT carbon dioxide diluent per year.
