Mass Transfer For a fixed number of ideal stages in a distillation column, as the reflux ratio is increased, the difference in composition between the top and bottom product streams Passes through a maximum Decreases Remains unaffected Increases Passes through a maximum Decreases Remains unaffected Increases 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 1 8 9 10 1 8 9 10 ANSWER DOWNLOAD EXAMIANS APP
