If If y2100РїРѓв„– = 6 (moles of toluene), compute % recovery of benzene in vapor phase by the following If y2100РїРѓв„– = 6 (moles of toluene), then temperature guess is correct. Step 6: Compute the moles of toluene in vapor phase by using the following relationship: Step 5: Calculate y2 (toluene mole fraction in vapor): Step 4: Solve y1 (benzene mole fraction in vapor) using the following equation: Step 3:Solve РїРѓв„– using the following equation: Step 2: Read vapor pressure at that temperature and calculate K values using Ki = Pis/P Let consider Benzene as component 1 and Toluene as component 2. We are looking for % recovery of benzene in the vapor = Р“вЂ”100% So Benzene in vapor phase, vB = (100РїРѓв„– - 6) mol Let the mole fraction of toluene in the vapor is yT.
