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. xB(Psat B) + (xT)(Psat T) = P
log10(Psat B) = 6.905 − (1211/ (T + 221))
log10(Psat T) = 6.953− (1344/ (T + 219 ))
At what temperature should the tank be operated to get the highest purity toluene in the liquid phase (maximizing xT)?
