If If y2100пЃ№ = 6 (moles of toluene), compute % recovery of benzene in vapor phase by the following If y2100пЃ№ = 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 пЃ№ 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 = Г—100% So Benzene in vapor phase, vB = (100пЃ№ - 6) mol Let the mole fraction of toluene in the vapor is yT. So, vT = (Toluene in vapor phase) = (60 -54) = 6 mole LT (Toluene in liquid phase) = 0.9Г—60 = 54 mole To increase the temperature as в€‘ziKi & lt 1 indicate subcooled feed mixture.ДЄfter a number of guess, we got Tbubble: 49 п‚°C For any Tguess if в€‘ziKi & lt 1, we have Guessing a lower temperature until we get в€‘ziKi = 1 or close to 1.

Required, however, a higher number of trials might be required if the first guess is very poor. We are looking for a value of V/F for which f(П€) = 0 or close to zero. Stage sufficient to meet the requirement?
