MEG Production Plant

MEG Production Plant
Product Description
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.
MEG is a colourless, odourless liquid with a syrup-like consistency.Mono-
ethylene glycol - or MEG - is a vital ingredient for the production of
polyester fibres and film, polyethylene terephthalate (PET) resins and engine
coolants.
The MEG plant provided by SL TEC has advantages as follows:
1. The pressure of the carbonylation unit is increased to 2.0-3.0MPa, about 5-
7 times the conventional process, thereby the diameter of main equipment and
pipes are reduced by 2-2.5 times.
2. The carbonylation reactor is changed from tubular type to plate type, whose
heat transfer effect is increased by one time, the catalyst loading coefficient
increased by over 60%, the STY (Space-to-Time Yield) more than doubled, which
allows the large scale of each production line.
3. The catalyst has better selectivity, higher conversion yield and longer
service time ( over 2 years)
4. The CAPEX of the carbonylation unit is reduced by 50%, while the investment
of the carbonylation unit takes 40% of the total investment.
