Ethylene Glycol Production from Ethylene Oxide (Direct Hydrolysis)
Ethylene Glycol Operating Costs & Plant Construction Costs
This assessment approaches the production of Monoethylene Glycol (MEG) from ethylene oxide in the United States. In the process under analysis, ethylene oxide is directly hydrolyzed to MEG. Diethylene glycol (DEG) and triethylene glycol (TEG) are also generated as by-products.
The report provides a comprehensive study of Ethylene Glycol production and related Ethylene Glycol production cost, covering three key aspects: a complete description of the Ethylene Glycol production process examined; an in-depth analysis of the related Ethylene Glycol plant capital cost (Capex); and an evaluation of the respective Ethylene Glycol plant operating costs (Opex).
The Ethylene Glycol production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Ethylene Glycol plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Ethylene Glycol plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises two major sections: (1) Ethylene glycol synthesis; and (2) Ethylene glycol purification.
Ethylene glycol synthesis. The ethylene oxide is combined with water, heated and fed to a tubular reactor, where the ethylene oxide is thermally hydrolyzed to Ethylene Glycol without a catalyst. As ethylene oxide reacts with ethylene glycols more quickly than with water, diethylene glycol (DEG), triethylene glycol (TEG) and heavy glycols are also formed. The yields of such glycols, however, are minimized by conducting the reaction in excess of water, what ultimately improves selectivity towards MEG.
Ethylene glycol purification. The excess of water used in the EG reaction is removed from the reactor outlet by means of multi-stage evaporator. Then, the MEG is purified in successive distillation steps, while residual water is recycled to the reactor as process condensate and DEG and TEG are recovered as by-products.

Ethylene Glycol from Ethylene (Carbonation without EO By-Product)
This study presents the economics of Monoethylene Glycol (MEG) production from ethylene in the United States. The process described is similar to Shell OMEGA. First, ethylene is oxidized with pure oxygen to produce ethylene oxide (EO). The EO is then carbonated to generate ethylene carbonate, which is finally hydrolyzed to MEG.

Ethylene Glycol Production from Carbon Dioxide
This study presents the economics of Monoethylene Glycol (MEG) production from carbon dioxide (CO2) in the United States using an electrochemical process similar to Liquid Light process. Initially, CO2 is electrochemically reduced and acidified into oxalic acid. Then, oxalic acid is esterified with methanol producing dimethyl oxalate, which is hydrogenated forming MEG.
