This paper is the second part of a continuing study on mass transfer in a reciprocating plate column. The first part dealt with k L a . The bubble size distribution, the Sauter mean diameter and the interfacial area are the subject of this paper. The bubble size increases slightly with gas flow rate and decreases with agitation intensity above a “critical” level. The interfacial area increases with increasing agitation and aeration intensities, while the liquid flow rate and coalescing properties of the liquid have no significant effect. The specific interfacial area is correlated in terms of the superficial gas velocity and the maximum power consumption. The correlations obtained for k L a and a were used to calculate k L . It was found that k L depends on the agitation intensity and the bubble size.
