Abstract: The steady-state simulation to the tail gas absorption process of ethylene oxide production unit is performed by using PROⅡ simulation software,based on the latest emission standards for pollutants.The impact of the cooling temperature of feed gas,the temperature and flow of absorbing agent,and the number of theoretical tray of absorption tower on the absorption efficiency are studied through single factor analysis method.Optimized process parameters are obtained.Besides,it is shown from the results that under the same conditions,using ethylene glycol solution can drastically reduce the consumption of absorbent comparing with that using condensate water,which has the advantages as follows:the utilizing rate of absorbent is higher,and the waste liquid generated after absorbing is non-toxic,safe and easy to treat.
