MARANGONI INSTABILITY DURING ABSORPTION ACCOMPANIED BY CHEMICAL REACTION

Abstract

Based on an extended model of Marangoni convection during absorption accompanied by chemical reaction certain characteristics of the process are studied. Thus, the probability of oscillatory modes occurring in the system is analysed, the dimensions of the convective cells are evaluated and the gas-liquid contact time necessary for the instability to appear is determined. The quantitative conclusions are compared with the reliant experimental data concerning the absorption of CO₂ into monoethanolamine in both wetted-wall and packed columns.
