Consider a PFR in a series with a CSTR (PFR is before theCSTR). Determine the required reactor volumes for the PFR (VPFR)and the CSTR (VCSTR) to give an overall treatment efficiency of 95%of compound A. Report in Liters.
a. Assume the overall system is at steady-state, theflow rate is 15 L/min, the detention time is the PFR is 1.5 hours,and the decay rate of compound A is defined by a first-order ratereaction (k = 1 h-1).
b. If the feed concentration of A is 250 mg/l, what isthe concentration in the line transferring the water from reactor#1 (PFR) to reactor #2 (CSTR)?
c. What is the detention time in the CSTR?
