ETHYLENE GLYCOL BASE-CASE PROCESS In this paper, the production of ethylene glycol was generated and based on two parts. There, ethylene glycol (MEG, Monoethylene glycol) is produced from EO by reacting it with water at a 10 to 1 ratio of water to EO. <>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>

In the early days of EO production, the typical start-of-cycle selectivity for EO catalysts ranged from 68 to 70%, i.e., 30% or more of the ethylene feed to the process was lost to the complete combustion side reaction. Ethylene is oxidized with oxygen to form ethylene oxide in a Figure 3.1 shows an innovation map, which illustrates the Ethylene glycol production The aqueous EO solution from the ethylene oxide production section is sent to the gylcol section. Due to its demand and a vast application area lot of research is going on for improving its production statistics.
