Mass transfer kinetics for interfacially perturbed vertical liquid films

Liquid side mass transfer has been investigated for pure carbon dioxide abs orption on interfacially perturbed vertical water liquid films. Perturbatio n was made by dropping low surface tension alcohol solutions on water film surface. The type of alcohol solutions, the dropping frequency and the numb er of the dropping points determine the increase of the mass transfer rate over the unperturbed state. Values obtained for liquid mass transfer coeffi cient in the CO2-water absorption present the evolution with operating para meters such as Ioan (1996) and Hikita (1959).
