Flash distilling liquid mixture containing 40 mol % A(LK) and 60 mol % B(HK)
The flow rate (F) of the mixture supplied to the drum is 100 mol/h.
a fraction (yA; unit) of A present in a (a) vapor phase obtained under the following design conditions.
mol % and (b) the recovery rate of B at this time (the amount of B obtained by liquid relative to the amount B present in the raw material); but
Calculate the % above. However, the relative frequency of A and B (αA-B) is 2.

Design condition: (V/F) fixed at 0.2.
