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 8 1 9 10 8 1 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Total cost first decreases and then increases Number of plates decreases very slowly first and then more and more rapidly Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Total cost first decreases and then increases Number of plates decreases very slowly first and then more and more rapidly ANSWER DOWNLOAD EXAMIANS APP
