Ethylene Glycol from Ethylene (Carbonation without EO By-Product)
Ethylene Glycol Operating Costs & Plant Construction Costs
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.
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 four major sections: (1) ethylene oxide synthesis; (2) ethylene oxide recovery; (3) ethylene glycol synthesis; and (4) ethylene glycol purification.
* Ethylene oxide synthesis. Ethylene and oxygen are reacted forming ethylene oxide. This exothermic reaction is conducted in multi-tubular reactor in the gaseous phase with the use of a silver catalyst supported on alumina.
* Ethylene oxide recovery. The reactor product stream is fed to an absorber for lights removal. Part of this gaseous overhead stream is recycled to the reactor, while the other part is sent to a CO2 removal unit. In this unit, CO2 is separated to be used in ethylene carbonate production. A diluted ethylene oxide stream from the absorber is subjected to a concentration step, residual light gases are removed and recycled to the reactor. The crude ethylene oxide obtained is sent to the ethylene glycol synthesis section.
* Ethylene glycol synthesis. Ethylene oxide is reacted with CO2, forming ethylene carbonate, which is then hydrolyzed to form MEG and CO2. Both reactions are carried out in the liquid phase using homogeneous catalysts. CO2 streams from the reaction steps are recycled to the ethylene carbonate reactor.
* Ethylene glycol purification. MEG produced is purified in two distillation columns where water is removed, leading to the final MEG product. The homogeneous catalyst is separated and recycled to the ethylene carbonate reactors.
