Mass Transfer Priming in a distillation column Is characterised by the presence of foam throughout the space between trays Results from very low gas velocity Reduces the overall pressure drop Is desirable from point efficiency consideration Is characterised by the presence of foam throughout the space between trays Results from very low gas velocity Reduces the overall pressure drop Is desirable from point efficiency consideration ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Total pressure is less Saturated steam is used for steam distillation Temperature is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Total pressure is less Saturated steam is used for steam distillation Temperature is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition ANSWER DOWNLOAD EXAMIANS APP
