| Abstract: | The performances of mass transfer in a wetted wall distillation column with external heating and cooling were investigated experimentally and theoretically at turbulent conditions of gas phase.The corresponding correlation of the mass transfer coefficients for the ethanol water system at total reflux conditions was presented,and it could be used to predict the mass transfer coefficients in the SRV distillation column. |

| Keywords: | wetted wall column non adiabatic distillation turbulence mass transfer |
