Journal of Chemical Engineering of Japan. ISSN 1881-1299. Vol. 23, n.º 5 (1990), p. 641-645http://hdl.handle.net/10400.14/5563The removal of a dilute solute from a gas mixture being injected through a submerged single nozzle with an instantaneous chemical reaction occurring on the gas/liquid interface is theoretically studied. An improved version of the double surface-renewal model for the molecular transport of solute is reported. The reasoning underlying this improvement arises from the decoupling of the bulk and overall concentration of solute in the bubble, and requires an extra parameter for full description. An analytical formula pertaining to the overall depletion of solute by reaction with time is obtained. Simplifications of this result are presented and discussed f or asymptotic behaviors. The propriety of the analysis for the modeling of experimental evidence is included.engMass transfer from bubllesInterfacial chemical reactionsDilute soluteSurface renewall modelMathematical simulationApproximate solutionjournal article10.1252/jcej.23.640
