American natural gas futures can produce ethylene glycol. The technology of producing ethylene glycol from natural gas accounts for about 27% in American futures. Ethylene glycol consists of natural gas conversion unit, synthesis gas separation, purification unit, ammonia oxidation, fresh esterification absorption unit, gas purification and cyclization unit, DMO synthesis unit, DMO separation and purification unit, DMO hydrogenation unit and EG separation unit, so the future natural gas in the United States can produce ethylene glycol.
