✦ Synopsis

CO, has been absorbed in a packed column into carbonate-bicarbonate buffer solutions containing arsenite as a catalyst. In these solutions COz undergoes a pseudo-first-order reaction. The results confirm that rates of absorption can be predicted on the basis of the Danckwerts surfacerenewal model. Values of the effective interfacial area, a, and the surface-renewal rate, s, are reported for & in. Raschig rings and various liquid flow-rates.

The effect of liquid phase mixing on first-order chemical absorption in a packed tower is considered. The rigorous equations are developed for a string-of-balls absorber, and their applicability to a random packing is considered. Particular attention is drawn to the case in which the reaction time i
