Abstract
Effective interfacial area and mass transfer coefficient were determined by the use of Danckwerts’plot method for chemical absorption system accompanied by first order reaction to elucidate the effect of shape and wettability of packing materials on these parameters.
The liquid phase used in this experiment was K2CO3-KHCO3 buffer solution, and NaOCl was used to catalyze the first order reaction in the liquid phase. Rasching ring, sequare, sphere in shapes, and these were made of ceramic polypropylene, glass, stainless steel, were used as packing materials.
The following correlations were obtained to predict the effective interfacial area and mass transfer coefficient.
a/at = 0.614Re0.161（ c/ ）0.119(atdn(1- )^1 over 3)-1.01
KL = 0.0154Ref 0.24( c/ )0.48(atdn)0.19
