Modeling and numerical analysis of counter-current dialyzer with chemical reaction in stripping solution

Original language description

In the present work, the effect of a second-order chemical reaction A + B reversible arrow 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.
