Popis:	We determined interfacial areas, A, and individual mass transfer coefficients, kL, for the absorption of CO2 in a bubble column, with an anionic surfactant in the absorbent liquid. The results of experiments to determine the dependence of kL on surface tension of the liquid phase and the superficial velocity of the gas were fitted to within a 10% error by expressions of the form k L =K 4 σ 1.35 u G 0.5 where K4 depends exclusively on the kind of bubbling device. Likewise, the experimental values of specific area, a, were correlated with the column diameter dc and the physical properties by means the following equation: ad c =K· Re 0.98 · Sc 0.57 · Fr 0.09 · Bo −0.70 d p d c −0.19 that reproduces satisfactorily the experimental values.
