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 8 1 10 9 8 1 10 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Entrainer used in azeotropic distillation should Form a low boiling azeotrope with one of the constituents of the mixture Have high latent heat of vaporisation Form a new azeotrope of low relative volatility with one of the constituents of the mixture Have high viscosity to provide high tray efficiency Form a low boiling azeotrope with one of the constituents of the mixture Have high latent heat of vaporisation Form a new azeotrope of low relative volatility with one of the constituents of the mixture Have high viscosity to provide high tray efficiency ANSWER DOWNLOAD EXAMIANS APP
