MEG Plant MEG Plant Agent Technology and Plants   Technology Introduction: 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. Technical Features: 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, a...

MMA Plant MMA Plant Agent Technology and Plants   Technology Introduction: There are three prevailing processes for MMA, or methyl methacrylate production , C-2 Process starting from ethylene, methanol and formaldehyde, C-3 Process (also called as ACH Process) which uses the byproduct of HCN from acrylonitrile production as the feedstock, and C-4 process which uses isobutene or tertiary butanol as the feedstock. SL TEC provides MMA plant based C-4 Process, consisting of three working units, i.e. oxidation unit, distillation unit and esterification unit. Technical Features: The MMA plant offered by SL TEC has advantages such as easy availability of feedstock, more environment friendliness, lower investment, lower production cost and etc. Performance: 1.
