Abstract (EN): The mass transfer of solute from a dilute gaseous mixture during bubble formation at the tip of a submerged nozzle in the presence of an instantaneous chemical reaction on the liquid side is simulated via a two-parameter model. This mechanistic model is developed from the general mass balance of solute by introducing a number of physically reasonable assumptions coupled with carefully checked mathematical approximations. Using data reported elsewhere, parameter estimates are found and a statistical analysis of their significance is presented. Experimental evidence is predicted much better than via other theoretical models. The analysis reported is useful for the preliminary design of industrial sparging vessels because most of the solute removal occurs during bubble growth.
