Mass transfer parameters are necessary for the design of absorption and desorption processes in packed columns. To determine the effective interfacial area and liquid side mass transfer parameters, CO 2 absorption and desorption are frequently used. Reliable analytics for concentration determination are essential to obtain correct results. In this work two methods of CO 2 liquid phase analysis are compared: first, the back titration of unreacted NaOH after prior precipitation of the bound CO 2 ; secondly, the inorganic carbon analysis with a commercial inorganic carbon analyzer.
