Conclusions The traditional feed stock used to produce ethylene glycol is petroleum. In recent years due to decreasing petroleum resources, and the high price of crude oil there has been a shift to use coal as feedstock. Coal gasification produces syngas, which primarily consists of hydrogen, carbon monoxide, and some carbon dioxide. The EG production process consists of four sub-sections
