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 In an operating distillation column, the Driving force for the liquid flow is its specific weight Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Highest temperature is encountered at the top of the column Vapors and liquids are at their dew point and bubble point respectively Driving force for the liquid flow is its specific weight Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Highest temperature is encountered at the top of the column Vapors and liquids are at their dew point and bubble point respectively ANSWER DOWNLOAD EXAMIANS APP
