Ethylene Glycol Production from Coal-Based Synthesis Gas

This review presents a technoeconomic evaluation of a newly commercialized monoethylene glycol (MEG) production route, which, if it successfully meets the desired level of product purity and catalyst stability, could revolutionize the MEG industry with the possibilities of switching its production from the current ethylene-based source to a new coal-based source.

ICIS WEBINAR: Chinese coal-based PVC, MEG losing

03/06/2020· “The production costs of these coal-based plants remain essentially unchanged and local ethylene-based alternatives have gained a cost advantage as the cost of these processes has fallen”, Healy said. He noted that China produces significant volumes of vinyl chloride monomer (VCM) a precursor to PVC production and ethylene glycols from coal, rather than ethylene.

Technology Profile: Ethylene Glycol Production from

Ethylene glycol, also known as monoethylene glycol (MEG), is a major chemical commodity, widely used in the production of polyethylene terephthalate (PET) bottle-grade resins and polyester fibers. These materials, in turn, are used to manufacture textiles, soft drink and water bottles, tire cords and more. MEG was first synthesized via the hydrolysis of ethylene glycol diacetate. Now, it can

Ethylene Glycol (EG) Production and Manufacturing

05/11/2007· Ethylene glycol used to be manufactured by the hydrolysis of ethylene oxide (EO) which was produced via ethylene chlorohydrin but this method has been superseded by a direct oxidation route. The EO is first produced by the oxidation of ethylene in the presence of oxygen or air and a silver oxide catalyst. A crude ethylene glycol mixture is then produced by the hydrolysis of EO with water
