The present study aimed to propose a general model for absorption with a non-elementary chemical reaction. The modeling of the system was conducted within the stagnant liquid film surrounding bubbles in the bubble column reactor. The finite difference method was used to solve the governing differential equations. The model was solved for the general reaction orders of components with a general boundary condition. Therefore, it includes all kinetic regimes based on the film theory and is capable of predicting the absorption system with a complex reversible or irreversible chemical reaction. Further, the effects of different parameters such as the equilibrium constant, the concentration of components, and chemical reaction orders on the absorption enhancement were investigated. The results indicated that the initial concentration and reaction order of components can significantly influence the absorption enhancement. Finally, In order to validate the model, the results were compared with those of the previous studies.

本研究旨在提出一种利用非元素化学反应进行吸收的通用模型。在气泡塔反应器中围绕气泡的停滞液膜内进行系统的建模。用有限差分法求解控制微分方程。求解了具有一般边界条件的组件的一般反应阶数的模型。因此，它包括所有基于薄膜理论的动力学机制，并且能够预测具有复杂可逆或不可逆化学反应的吸收系统。此外，研究了平衡常数，组分浓度和化学反应顺序等不同参数对吸收增强的影响。结果表明，组分的初始浓度和反应顺序可以显着影响吸收增强。最后，为了验证模型，将结果与以前的研究进行了比较。
