摘　　要：国内对常规活化MDEA法脱碳的应用已趋于成熟,但鲜有对活化MDEA半贫液工艺(二段吸收+(闪蒸+汽提))全面的分析和研究。为此,本文针对半贫液工艺采用ASPEN HYSYS软件进行模拟,活化剂选用PZ(哌嗪),物性方程选择DBR Amine package,得出模拟结果,并从活化剂配比、半贫液分流比、进料温度、吸收塔板数和再生温度等方面进行分析。结果表明:半贫液工艺适用于不高于40%的场合,PZ浓度宜选择4%~6%,半贫液分流比宜选择0.6~0.7,进料温度宜选择40℃~45℃,最佳的理论板数为20~25块,最佳再生温度为95℃~100℃。该研究结果对工艺的实际应用具有一定参考意义。The researches on MDEA are comprehensive, but lack of analysis on Semi-lean solution process.This paper simulated the Semi-lean solution process by ASPEN HYSYS software and then gets results by choosing PZ as activator and DBR package as computing method. The flow has been analyzed on activator mass concentration,Semi-lean solution ratio,absorbing stages and the temperature of N-methyldiethanolamine（MDEA） and reboiler.The result shows that Semi-lean process is appropriate for the situation less than 40 per-cents,and then selecting from 4 to 6 percents as activator ratio,from 0.6 to 0.7 as Semi-lean solution shunt ratio and from 20 to 25 as absorbing stages are suitable.Then the temperature of N-methyldiethanolamine（MDEA）and reboiler are from 40 to 45 and from 95 to 100 degrees centigrade separately.This conclusion makes an useful foundation on practical application.
