The Absorption of CO2 by Aqueous NaOH in Packed Column

The simulation is by using standard Reynolds mass flux model the model equation sets, the boundary conditions, and the evaluation of source terms are the same as given in Sect. 5.1.3. The simulated results are given in the following sections. 

The simulated profile of liquid-phase temperature for experiment T11 is shown in Fig. 5.35 and compared with experimental data. The simulated temperature at the column bottom is somewhat higher than the experimental measurement due to the same reason for the case of MEA absorption as stated in Sect. 5.2.1.1. 

The simulated profile of OH for Til is given in Fig. 5.36. The simulated radial averaged axial concentration is seen to be confirmed by the experimental data. 

The radial distribution of axial liquid-phase velocity 

The radial averaged axial liquid-phase velocity is shown in Fig. 5.37. As seen in the figure, wavy fluctuating of axial velocity in this case may be due to the
