A+B P+S is a liquid phase reaction that is used to produce the desired product P in a plant. The data of the reaction is tabulated below. The product Pis produced by using a plug flow reactor (PFR) in the plant. The product concentration in the exit stream is 0.10 mol/L. According to the new target of the management the product concentration in the exit stream is required to be increased to 0.15 mol/L. According to this new target, the first design engineer (DE-1) suggested using BMR following the existing PFR. Second design engineer (DE- 2) suggested to use BMR before the PFR. Supposing that you are the third design engineer (DE-3) what would you suggest in order to increase the product concentration to the desired value. Data: FAD = Fgo = 32 mol/min Q. = 167 L/min Note: Show the calculations of all alternative design approaches clearly.
