Abstract

We studied gas absorption from a rising gas plug when the concentration level of the absorbate in the absorbent is finite (finite dilution of absorbate approximation). It is shown that in the case of the finite dilution the lateral convective term in the equation of convective mass transfer in the absorbate must be taken into account. It is found that the mass transfer rate increases with the increase of the absorbate concentration level. Isothermal and nonisothermal absorptions are considered whereby the latter is described by the coupled equations of mass and heat transfer. It is found that the mass transfer rate decreases when the dimensionless heat of absorption increases.
