摘　　要：应用Aspen Plus软件模拟计算了以氢氧化钠水溶液为吸收剂脱除尾气中硒化氢组分的化学吸收过程。分析讨论了吸收剂流量、浓度、温度等参数对脱除效果的影响,得出适用于模拟工况吸收过程的设计操作条件。模拟结果可以为实际工业设计及操作过程提供参考依据。The removal of hydrogen selenide component using aqueous solution of sodium hydroxide was simulated with Aspen Plus. The influence of flow rate,temperatures and concentration of absorbent on absorption were analyzed. The results indicate that the hydrogen selenide can be effectively removed by the reaction with sodium hydroxide solution via a chemical absorption process. The design and operating parameters applied to the simulating condition were obtained,and the simulation results can be used as reference for the future actual process.
