Mass transfer in a short wetted-wall column. 2. Binary systems

Nieuwoudt I. ; Crause J.C. (1999)


Mass-transfer coefficients were measured in a short wetted-wall column by evaporating binary liquid mixtures. These mass-transfer coefficients were compared with the gas-phase transfer coefficients reported in part 1 of this series. For the systems used in this study, enhanced mass transfer was observed when mixtures having large differences in pure component surface tensions were evaporated. For these systems, an increase in surface rippling was observed. This mass-transfer enhancement was not exhibited in binary systems with small differences in pure component surface tensions.
