✦ Synopsis
Values of the liquid-side mass transfer coefficient, kL and the interfacial area, a per unit volume of froth on a sieve plate (perforated area 55%) were found using the technique of absorption accompanied by irreversible pseudo-first order reaction. The experiments were carried out with several reacting systems, for which the attained values of kL and n were O-17-0.27 cmlsec and 1*97-2.28 cm*/cmS respectively. A method has been employed, which enables these values to be determined without the necessity of measuring kinetic constants. The results confirmed that the Danckwerts equation could be used to predict rates of absorption in sieve plate columns.
