Gas absorption in a countercurrent packed tower

Book Description
The surface renewal rate from Danckwerts' theory and the effective interfacial area between gas and liquid per unit packing volume in a packed absorption tower were evaluated for the absorption of carbon dioxide into carbonate/bicarbonate buffer solution accompanied by a pseudo-first order chemical reaction. The rate of chemical reaction in the liquid phase was controlled by varying the buffer ratios. A small absorption tower was constructed, which had a packing section, 30 cm high with 10.2 cm inside diameter. Two kinds of packing, 1/2-inch Rasehig ring for one part of the experiment and 1/2 inch Ben saddle for the other part of the experiment, were used in the investigation. Sodium carbonate/bicarbonate buffer solutions, with buffer ratios varying from 0.4 to 3.0, were used. Glycerine-water solutions were also used to investigate the effect of density and viscosity on the physical absorption of carbon dioxide; the content of glycerine varied from 0 to 40 % wt. Pure carbon dioxide was used to eliminate the gas side resistance in the mass transfer operation. The results of this investigation suggested the following conclusions: The surface renewal rate, s, and the effective interfacial area per unit packing volume, a, for each packing can be expressed as functions of Reynolds Number of the liquid flow. The comparison of values from this study with those of Danckwerts showed discrepancies; these discrepancies could be due to different flow patterns, packing densities, and the apparently more uniform distribution of liquid over the packing. The mass transfer coefficient for physical absorption into glycerine solution was expressed as a function of Reynolds number and Schmidt number. The mass transfer coefficient calculated from Danckwerts' model equation, kL*a = [Ds divided by a*] for absorption of carbon dioxide into water seemed to be larger than those measured in this experiment.
