N-甲基二乙醇胺选择性吸收H_2S过程的模拟分析

Operation Optimization and Computer Simulation for MDEA Selective Absorption H_2S

以实际脱硫装置的运行数据为基础， 根据Ｈ_２Ｓ， ＣＯ_２ 在Ｎ－甲基二乙醇胺 （ＭＤＥＡ） 水溶液中的反应机理和反应速率方程， 建立了描述该脱硫系统的数学模型， 经模拟计算， 得到了现装置的实际处理能力， 确定限制装置生产能力的瓶颈为吸收塔， 提出了现有装置的操作方案，

Reaction mechanism and reaction tate equation are given for selectively absorbing H 2S with MDEA,and a mathematical model is developed by computer technique on the basis of differential equations,The actual handing capacity for operating system is obtained,and a conclusion can be drawn that the absorption tower is a bottleneck and simulation results an operationl optimization is developed.
