Abstract
We studied gas absorption from a rising spherical bubble when the concentra tion level of the absorbate in the absorbent is finite (finite dilution of absorbate approximation). It is showed that in the case of finite dilution the lateral convective term in the equation of mass transfer of the absorba te must be taken into account. It is found that the rate mass transfer and the rate of bubble collapse increases with the increase of the absorbate co ncentration level. Isothermal and nonisothermal absorptions are considered whereby the latter is described by coupled equations of mass and heat trans fer. It is showed that the rate of mass transfer and the rate of bubble col lapse decreases when the heat of absorption increases.
