Abstract

Abstract: 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, CO2 absorption and desorption are frequently used. Reliable analytics for concentration determination are essential to obtain correct results. In this work two methods of CO2 liquid phase analysis are compared: first, the back titration of unreacted NaOH after prior precipitation of the bound CO2 ; secondly, the inorganic carbon analysis with a commercial inorganic carbon analyzer. Abstract : Component concentrations are important for the determination of mass transfer parameters for absorption and desorption in packed columns. In this work two methods are compared. These are a standard titration method and an infrared‐based inorganic carbon analysis. The comparison is based on concentrations and HTUOL experimental data.
