Mass Transfer In a distillation operation, what is the effect of the temperature of the reflux stream (given below) on the condenser and reboiler loads? Reflux conditions:(i) Reflux stream is completely liquid and is at its bubble point.(ii) Reflux stream is below its bubble point. Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Condenser load is the same in both the cases but reboiler load is higher in case (ii) Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Condenser load is the same in both the cases but reboiler load is higher in case (ii) ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer In a single stage extraction process, 10 kg of pure solvent S (containing no solute A) is mixed with 30 kg of feed F containing A at a mass fraction xf = 0.2. The mixture splits into an extract phase E and a raf-finate phase R containing A at xB = 0.5 and xR = 0.05 respectively. The total mass of the extract phase is (in Kg) 6.89 8.89 8.25 10 6.89 8.89 8.25 10 ANSWER DOWNLOAD EXAMIANS APP
