The following schematic shows a process where the concentration of a Chemical A is reduced in 2 CSTRs in series (CA1(t) and CA2(t) in mol/L). The CSTR volumes, V=300L each. The 1st order reaction rate constants k1=2/31/min in CSTR1 and k2=1/31/min in CSTR 2, (maintained by different temperatures). Upstream of reactor 1 is a storage-cum-mixing tank, Tank 0 , of Volume, V0=800L, (used to reduce the variability in the feed to the reactors). The Input concentration, CAi(t) varies with time. Pure make-up liquid A is added to the CSTR1, at a molar flow rate of mmols/min, which is the manipulated variable used to maintain, CA2(t), at its desired value. The volume of this make-up stream is negligible. The liquid volumetric flow rate through the system, q=100L/min, which is time invariant. Develop the Unsteady state material Balances for each reactor / Tank, with numeric coeffs. 1.2 Assuming that the valve transfer function (TF) is GV(s), the measurement system TFM(s)=1 and the Feedback Controller Transfer function is GC(s), Develop the complete block diagram for the FEEDBACK Control Loop for controlling CA2(t) (without any feed-forward controller)
