Question 1 (50 Marks) A flash drum operating at 60C is to separate 50mol/s( feed =F) of solution of benzene and toluene containing 44% Benzene ( xF=z=0.44 ) into vapor (V) and liquid (L) streams. The vapor pressure of both components can be described using the Antoine-equation: log10P(mmHg)=AT(C)+CB with for benzene: A=7.4787,B=1701,C=294 and for toluene: A=7.4195,B=1738,C=273.5 a) Calculate the saturation pressures of Benzene and Toluene b) What is the operating pressure of the flash drum? c) Calculate the distribution coefficients and relative volatility d) Build xy diagram at the temperature of the drum. e) What is the q value and slope of operating line? f) Draw the operating line and find the intersection of operating and equilibrium lines g) What is the purity of the top and the bottom stream
