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
Condenser load is the same in both the cases but reboiler load is higher in case (ii)
Reboiler load is the same in both the cases but condenser load is higher in case (ii)
Both condensor and reboiler loads are higher in case (ii) as compared to case (i)

Mass Transfer
Compound A is extracted from a solution of A + B into a pure solvent S. A Co-current unit is used for the liquid-liquid extraction. The inlet rate of the solution containing A is 200 moles of B/hr.m² and the solvent flow, rate is 400 moles of S/m². hr. The equilibrium data is represented by Y = 3X² , where Y is in moles of a A/moles of B and X is in moles A/moles of S. The maximum percentage extraction achieved in the unit is

0.25
0.5
0.9
0.7
