Mass Transfer A distillation column with N plates is being operated under normal conditions. At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped). At the new steady state, Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions correspond to the maximum enrichment available Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions correspond to the maximum enrichment available Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux ANSWER DOWNLOAD EXAMIANS APP

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 9 10 1 8 9 10 1 8 ANSWER DOWNLOAD EXAMIANS APP
