Ethylene glycol (EG), one of the important basic chemical raw materials, is widely used in producing polyester and antifreeze (Wei et al., 2018).As the production capacity of polyester increases year by year, the demand for ethylene glycol is greatly stimulated. This is done by coal gasification. However, a production of ethylene glycol through hydrolysis of ethylene oxide needs a lot of water in the reaction phase reaching production specification which cause a high-energy demand in water distillation unit (Rao et al., 2007).
