Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Temperature is less Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Total pressure is less Temperature is less Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Total pressure is less ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Back-trapping in a distillation column Increases tray efficiency Reduces pressure drop Decreases tray efficiency Is desirable, as it provides improved vapour-liquid contact Increases tray efficiency Reduces pressure drop Decreases tray efficiency Is desirable, as it provides improved vapour-liquid contact ANSWER DOWNLOAD EXAMIANS APP
