The liquid phase dimer-quadmer series addition reaction

and is carried out in a 10 dm3 PFR. The mass flow rate through the heat exchanger surrounding the reactor is sufficiently large so that the ambient temperature of the exchanger is constant at Ta = 315 K. The reactants enter at a temperature T₀, of 300 K. Pure A is fed to the rector at a volumetric flow rate of 60 dm3/s and a concentration of 2 mol/dm³

(a) Plot, compare, and analyze the profiles F_A, F_A, and F_A, down the length of the reactor up to 12 dm³.

(b) The desired product is A₂
and it has been suggested that the current reactor may be too large. What reactor volume would you recommend to maximize F_A,?

(c) What operating variables (e.g., T₀, T.) would you change and how would you change to make the reactor volume as small as possible and still to maximize F_A,? Note any opposing factors in maximum production of A₂. The ambient temperature and the inlet temperature must be kept between o·c and 177C.

Tum in your recommendation of reactor volume to maximize F_A, and the molar flow rate at this maximum.
