Toluene is hydrodealkylated to benzene, with a conversion per pass through the reactor of 70%. The toluene must be recovered and recycled. Typical conditions for the feed to a commercial distillation unit are 100^οF, 20 psia, 415 lbmol/h of benzene, and 131 lbmol/h of toluene. Using the property constants below, and assuming the ideal-gas, ideal-liquid-solution model of Table 2.4, prove that the mixture is a liquid and estimate v_L and p_L in American Engineering units.
Property constants for (2-39) and (2-38), with T in K, are:
