![7. [10 pts] A mixture of benzene and toluene are to be separated in a flash tank. The pressure in the flash tank is 800 mm Hg. The units for Antoines equation are mm Hg and °C for pressure and temperature, respectively. 10910(Poat B) = 6.905-1211 T +221 log10(P,at T-6 953-T + 219 (a) At what temperature should the tank be operated to get the highest purity toluene in the liquid phase (maximizing aT)?](http://img.homeworklib.com/questions/e2b48850-c88a-11ea-8a7e-85d5dcb139c9.png?x-oss-process=image/resize,w_560)

2. Using a separator flash valve, a binary mixture of Benzene (1) and Toluene (2) is flashed to 80 kPa and 95 °C. Laboratory analysis of the effluent liquid and vapor streams from the separator yields x1 = 0.165 and y1 = 0.287. An operator comments that the product streams are "off-spec" and the engineer is asked to diagnose the problem. (a) How will you verify whether the operator's comment is right or not?
