6. You are designing a reactor for a liquid-phase process in which an inlet stream of 100 mol/min of pure reactant A (CAo = 20 mol/l) is to be converted to product B in an irreversible elementary reaction: A →B. a. What size PFR is necessary to achieve 60% conversion if the reactor is operated isothermally at 500 K? (Ans= 9.165 L) b. Your customer decides that they would rather use an adiabatic CSTR than the isothermal PFR from part a. If the target is still 60% conversion, what size CSTR is needed if the reactor feed is held at 500 K? (Ans= 2.64 L) Data: k(T=500K)=0.5 min-1 Ea=65 kJ/mol AHrxn (500K) = -10 kJ/mol Cp,a = Cp,B= 60 J/(molK). Activate v Go to Setting
