The axial mixing influence on the number stages of countercurrent absorbers in absorbing NH3-CO2-H2O mixture in NaCl-H2O system

This paper investigates the influence of axial or longitudinal mixing of stages on the number stages in a countercurrent absorber in absorbing vapour-gas mixture of NH3-CO2-H2O in the multicomponent system NaCl-H2O. The number stages in ideal mixing of phases NT and the number of stages which involves axial mixing ND were determined. The authors of this paper conclude that the influence of axial mixing does not affect the number stages in the countercurrent absorber. Otherwise, absorption in this concrete system is practically present in the process of soda ash production.
