Determination of Interfacial Areas in a Bubble Column by Different Chemical Methods

Abstract

We determined interfacial gas−liquid areas for the absorption of CO2 or O2 in a bubble column, with and without surfactants and/or sucrose in the absorbent liquid. All the experiments were carried out under batch processing conditions. The values obtained by the three chemical methods used have been compared, and the dependence of the operating conditions and physical properties on the interfacial area has also been analyzed. The results of experiments to determine the dependence of the area on the geometrical characteristics of the column and physical properties were fitted to within an 8% error by dimensionless modules.
