Mass Transfer Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (yin = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is, N+2 = 6 log (yin/yout).For 98% recovery of acetone, the number of trays required is/are 1 10 8 9 1 10 8 9 ANSWER DOWNLOAD EXAMIANS APP
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) 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) 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) 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) ANSWER DOWNLOAD EXAMIANS APP
