Question

Best arrangement of reactors for a reaction whose rate-concentration curve that rises monotonically.

(a) Plug, Large MFR, Small MFR

(b) Plug, Small MFR, Large MFR

(c) Large MFR, Small MFR, Plug

(d) Small MFR, Plug, Large MFR

I had been asked this question in examination.

My question comes from Choosing of Right Reactor Series or Connections (Maximum Profitability) topic in chapter Ideal Reactors for a Single Reaction, Conversion and Reactor Sizing of Chemical Reaction Engineering

Answer 1

Right option is (b) Plug, Small MFR, Large MFR

The best I can explain: For this kind of rate-concentration curve, the concentration should be kept as high as possible, therefore this arrangement should be used.
