Mass Transfer According to the Fenske equation, what will be the minimum number of plates required in a distillation column to separate an equimolar binary mixture of components A and B into an overhead fraction containing 99 mol% A and a bottom fraction containing 98 mol% B? Assume that relative volatility (αAB = 2) does not change appreciably in the coloumn. 6 8 12 10 6 8 12 10 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly ANSWER DOWNLOAD EXAMIANS APP
