The following reactions are carried out isothermally in a 50 dm3 PFR: A+2B C+D FDI=DICAC 2D+3A C+E =K2CACD B+2C >>D+F =k₁CC Additional information: Liquid phase kp 0.25 dm/mol2 min Uo 10 dm³/min = 0.1 dm³/mol min CAD = 1.5 mol/dm³ K3 5.0 dm/mol²-min Сво - 2.0 mol/dm³ (a) Plot the species concentrations and the conversion of A as a function of the distance (i. e., volume) clown a 50-dm3 PFR. Note any maxima. (b) Determine the effluent concentrations and conversion from a 50-dm3 CSTR. (Ans: CA = 0.61 , CB = 0.79, CF = 0.25, and CD = 0.45 mol/dm3.) (c) Plot the species concentrations and the conversion of A as a function of time when the reaction is carried out in a semibatch reactor initially containing 40 dm3 of liquid. Consider two cases: (I) A is fed to B, and (2) B is fed to A. What differences do you observe for these two cases? (d) Vary the ratio of B to A (I<OB<10) in the feed to the PFR and describe what you find. What generalizations can you make from this problem? (e) Rework this problem for the case when the reaction is a gas-phase reaction. We will keep the constants the same so you won't have to make too many changes in your Polymath program, but we will make u0 = 100 dm3/min, CTO = 0.4 mol/dm3, V = 500 dm3 and an equimolar feed of A and B. Plot the molar flow rates and SC/D and SE/F clown a PFR. (f) Repeat (e) when D diffuses out through the sides of a membrane reactor where the mass transfer coefficient, KCD, can be varied between 0.1 min-1 and 10 min-1. What trends do you find? (g) Repeat (e) when B is feel through the sides of a membrane reactor.
