| 摘 要： | 探讨了CO2和SO2膜吸收过程中的传质机理，并建立了数学模型。采用正交配置法求解模型，模拟了不同类型反应的反应物和产物在膜器内的浓度分布。模拟结果表明：反应动力学的不同是造成浓差极化的主要原因，为进一步弄清膜吸收过程传质机理提供了参考。

| Abstract: | Membrane absorption is a novel technique for treatment of acidic gas,however,the mechanism of this process is still not clear.The mass transfer behavior of SO_2/NaOH and CO_2/NaOH is different,and the reason of this deviation was discussed by several literature with different opinions.A mathematical model to describe the process was proposed in this study,and the concentration profiles of the reactant and product in the module were simulated.Results proved that the dynamic of the reaction is the reason of that deviation. |
