Abstract

<p>The paper deals with the determination of parameters of a cascade of ideal mixers (i.e. their number and mean residence time of liquid in each member) in modelling the liquid flow on a plate with mobile packing. The number of cascade members has been found practically independent of the gas and liquid velocities and the static bed heights in the gas velocity range from 1.0 to 3.5 m s<sup>-1</sup>, liquid velocity range from 5.36 . 10<sup>-3</sup> to 12.5 . 10<sup>-3</sup> m s<sup>-1</sup>, and the range of static bed height from 21 . 10<sup>-3</sup> to 47 . 10<sup>-3</sup> m. The mean residence time is increased with increasing static bed height and is decreased with increasing velocities of both gas and liquid. The calculated parameters of the model of flow of liquid and the experimental data on desorption of CO<sub>2</sub> from water by a stream of air have been used to calculate the values of mass transfer coefficient in liquid which have been compared with those obtained from the dispersion model. The both approaches have been found to give practically identical results.
