There are two main routes for Ethylene Glycol (Monoethyle Glycol/MEG)
production: one is the Olefin/EO(Ethylene Oxide) Route starting from either
naphtha, ethane or methanol, the licensors include Shell, SD, UCC and etc. And
the other is the DMO(dimethyl oxalate) Route newly emerged in China these years,
starting from syngas. Depending upon the difference operation pressure, this DMO
Route is further divided into Normal Pressure Process and Medium-High Pressure
Process.
SL TECH offers the most advanced and the most competitive Medium-High
Pressure DMO Process for MEG production. Its production cost is much lower than
that of Olefin/EO Process at the current low oil price (i.e., USD 67/ BBT), not
to mention the Normal Pressure DMO Route.
