Wetting and mass transfer in film columns . Calculation of mass transfer in film columns requires a fundamental knowledge about the wetting of the materials comprising the packing bodies. Starting from thermodynamic principles for a description of the solid/liquid interface, methods are discussed which permit an exact calculation of the basic parameters of wetting. It is also shown how the goal of ideal wetting can be approached by choice of material, modification of the surface of the packing bodies, and use of additives. Experience gained with regard to the effect of the various measures on the separation performance leads to conclusions concerning the determination of dimensionless equations for prediction of separation performance.
