Use the two film theory, and assume that the film thickness is 0.01cm for both gas and liquid phase. Which phase has more resistance for the overall mass transfer? 21 WebSingle film control It is possible that one of the films exhibits relatively high resistance and therefore dominates the overall resistance to transfer.

The CO 2 uptake capacity of the PLs decreased with temperature but increased with pressure and CO 2 concentration. Subsequently, the absorption-adsorption model was established to predict the CO 2 uptake capacity of PLs. red cheer shorts girls
