titleOfInvention |
Processes and systems for the recycle of process water in the production of ethylene glycol |
abstract |
Processes for producing ethylene carbonate and/or ethylene glycol, and associated reaction systems are similarly provided. Specifically, a process is provided that comprises supplying an overhead absorber stream withdrawn from an absorber to a vapor-liquid separator to yield an aqueous bottoms stream and a recycle gas stream; supplying an aqueous process stream comprising one or more impurities to a distillation apparatus to yield an overhead impurities stream and a purified aqueous process stream; supplying at least a portion of the purified aqueous process stream and an ethylene oxide product stream to the absorber; and contacting the ethylene oxide product stream with the purified aqueous process stream in the absorber in the presence of one or more carboxylation and hydrolysis catalysts to yield a fat absorbent stream comprising ethylene carbonate and/or ethylene glycol. |
