[6] Q2(a) A gas absorber is used to remove benzene (CeHe) vapors from air by scrubbing the gas mixture with a nonvolatile oil at 300K and 1 atm. At a certain point in the absorber, the benzene mole fraction in the bulk of the gas phase is 0.02, while the corresponding interfacial benzene gas- phase concentration is 0.00158. The benzene flux at that point is measured as 0.62 g/m2 s. (1) Identify the given data with neat diagram Calculate the individual mass transfer coefficient in the gas phase at that point in the equipment, expressing the driving force in terms of mole fractions If the benzene fraction in the bulk of the liquid phase is 0.125, while the corresponding interfacial benzene liquid-phase concentration is 0.158. Calculate the individual mass-transfer coefficient in the liquid phase, expressing the driving force in terms of mole fractions. [8] iii) [6]
