低温甲醇洗酸性气体吸收塔模拟分析

Simulation and optimization of methanol absorber in rectisol process

利用PRO/Ⅱ软件对低温甲醇洗工艺中的酸性气体吸收塔进行了模拟,选用NRTL热力学模型,在成功模拟的基础上对吸收塔的3个操作变量——甲醇温度、甲醇流量、分流分率分别进行了灵敏度分析,并进行了吸收塔液气比的优化分析。

PRO/Ⅱ software is used to to simulate the methanol absorber in rectisol process.The NRTL equation is chosen to describe the system.The effects of flow rate,temperature and diversion of methanol on the sensitivity are studied.The optimization of the liquid-gas ratio in methanol absorber is performed as well.
