2. REACTOR SELECTION The batch experiments carried out to study the removal of COD in water revealed that COD decayed (it was removed) following first order kinetics with rate constant k = 0.1 min at 20C. You are asked to make a comparison between two ideal flow reactors for the continuous flow design of the treatment process (a) Ideal CMFR (Completely Mixed Flow Reactor) und (b) ideal PFR (Plug Flow Reactor). Space limitations are critical and you are asked to select the smaller of the two reactors. Flow rate 1000m/min and target COD removal in the reactor is 90 percent. Determine which of the two reactors will suit the objective of the design. (25 points)
