| Abstract: | The theoretical analysis of optimization for water content in feedstock to ethylene oxide distillation section of ethylene glycol plant is made. Under the premise of ethylene oxide absorbed completely, the water distribution process for ethylene oxide re-absorber and glycol hydrate reactor is optimized, and simulation calculated for the technology with software of Aspen Plus. It has been affirmed that because of the water content reduced in feedstock to the purified column for ethylene oxide, production of the ethylene oxide can be increased by 14.8%, and the steam consumption decreased by 4.8% under the condition of same load. |
