Two film theory gas absorption
WebThe theory of gas-liquid mass transfer and design of such systems then follow. 1. ... Hence the terminology “two” film and these are referred to as gas film and liquid film. ... -7 … WebThe two-film theory of Lewis and Whitman defines these resistances separately, a gas film resistance and a liquid film resistance. They are treated very similarly to surface heat coefficients and the resistances of the two films can be combined in an overall resistance similar to an overall heat transfer coefficient.
