摘　　要：乙二醇脱烃分离单元是海上气田乙二醇再生及回收系统中重要操作单元之一。利用AspenPlus软件进行乙二醇脱烃分离单元的工艺参数设计,并提出技术优化方案。结果显示:脱烃分离单元最佳闪蒸温度和闪蒸压差分别为75℃、0.12 MPa;脱烃分离单元热负荷随着进料温度的升高明显降低,进料温度为20℃时脱烃分离单元热负荷数值是进料温度为50℃时热负荷数值的2倍;脱烃分离器采用水力旋流技术和斜板技术相结合的方式,可有效地提高总烃脱除率。The ethylene glycol dehydrocarbon separation unit is one of the important operation units in ethylene glycol regeneration and recovery system of offshore gas field. In this paper, Aspen Plus software was used to design the process parameters of ethylene glycol dehydrocarbon separation unit, and the technical optimization scheme was proposed. The results showed that the optimum flash temperature of dehydrocarbon separation unit was 75 ℃,and flash pressure drop was 0.12 MPa;The thermal load of dehydrocarbon separation unit decreased obviously with the increase of feed temperature, the heat load value of the dehydrocarbon separation unit with the feed temperature of 20 ℃ was twice that of the heat load value when the feed temperature is 50 ℃;The combination of hydrocyclone technology and inclined plate technology could effectively improve the total hydrocarbon removal rate.
