Simulation And Optimization Of Ethylene Glycol Production

Ethylene glycol production from syngas using gas-phase hydrogenation of dimethyl oxalate on a copper-based catalyst is one of the crucial technologies. Optimization on the conversion, selectivity and yield of industrial scale production is difficult to be done using experimental base approach. Hence...
