An acid-catalyzed irreversible liquid-phase reaction A B is carried out adiabatically in a CSTR. The reaction is second order in A. The feed is equimolar A and solvent (S, which contains catalyst), and enters the reactor at a total volumetric flow rate of 10 dm3/min at a concentration of A of 4 mol/L. The feed enters at 300 K. The product and reactant heat capacities are 15 cal/(mol°C), the solvent is 18 cal/(mol°C). The reaction rate constant at 300 K...

5.33. When B is mixed with A, the liquid phase reaction A+BC rkCA has a rate constant k 0.2 min. This reaction is to be carried out isothermally in a CSTR at steady state. The reactant A costs $2/mol and reactant B costs $0.10/mol. The product C sells for $6/mol. The cost of operating the reactor is $0.05 per liter per hour. We wish to produce 360,000 moles of C per day to meet the market demands The available reactants,...

3. The gas phase reaction A B -C, withkCACB, is to be carried out in a steady-state PFR with feed composition of 60% A. 40% B, 0% C and 0% inerts. In the 50 L reactor, 60% of the stoichiometrically limiting reactant is converted. It is desired to achieve 85% conversion of this reactant by placing a CSTR after the PFR. How large should the CSTR be? Consider constant pressure operation in both reactors.
