Abstract In the present work, the effect of a second-order chemical reaction A + B ⇌ P (both irreversible and reversible) in the stripping solution on the performance of a counter-current dialyzer is analyzed. An instantaneous irreversible reaction with an excess of a reactive component in the stripping solution results in the maximum attainable enhancement in the extraction ratio of the transported solute. The actual enhancement can be limited by low values of the forward reaction rate constant and equilibrium constant. These effects can be compensated by an excess of the reactive component in the stripping solution. As an alternative to rigorous modeling of mass transfer in the liquid film accompanied by a chemical reaction, the enhancement factor concept can be adopted. This approach has the advantage of the significant reduction of the overall complexity of the mathematical model without significant loss of its accuracy.

逆流透析器在汽提液中发生化学反应的建模与数值分析

摘要 在目前的工作中，分析了汽提液中的二级化学反应 A + B ⇌ P（不可逆和可逆）对逆流透析器性能的影响。与汽提溶液中过量反应组分的瞬时不可逆反应导致输送溶质提取率的最大可达到的提高。实际的增强会受到正向反应速率常数和平衡常数的低值的限制。这些影响可以通过汽提溶液中过量的反应组分来补偿。作为伴随化学反应的液膜中传质的严格建模的替代方案，可以采用增强因子概念。
