以实际脱硫装置的运行数据为基础，提出了 Ｈ２ Ｓ， Ｃ Ｏ２ 在 Ｍ Ｄ Ｅ Ａ 水溶液中的反应机理和反应速率方程，利用渗透理论，建立了以机理为基础的 Ｍ Ｄ Ｅ Ａ 脱硫流程模拟系统。经模拟计算，找出了该装置用于处理酸性废气净化率不达标的原因，确定限制装置生产能力的瓶颈为吸收塔，同时提出了现有装置的优化操作方案。
Based on the operating data of the actual desulfurization unit, the reaction mechanism and reaction rate equation of H2S and C O2 in aqueous solution were proposed. Based on the theory of permeation, a mechanism-based simulation of MADA desulfurization process was established system. The simulation calculation shows that the device is used to deal with the reason that the acid gas purification rate is not up to standard, and the bottleneck to limit the production capacity of the device is the absorption tower. At the same time, the optimized operation plan of the existing device is proposed.
