One of the key problems in sizing separation columns is determining the effective interfacial area and the mass transfer coefficients in the two phases involved. From experimental investigations it is usually possible to find only the product of the interfacial area and overall mass transfer coefficient. Here it is demonstrated for the first time that the effective interfacial area does not only depend on the fluid dynamics of the column and chemical data of the liquid but also significantly on the rate of mass transfer.
