Question

The following reactions are carried out in an isothermal continuous stirred tank reactor. A$\rightarrow$B B$\rightarrow$C $-r_A = k_1C_A$ $k_1 = 1.1$ min$^{-1}$ $-r_B = k_2C_B^2$ $k_2 = 0.1$ m$^3$/kmolmin B is desired product and concentration of B is controlled using PI controller. The feed stream of 1 m$^3$/min containing 0.8 kmol/m$^3$ at steady state operation passes through the reactor having a volume of 2 m$^3$. If the volume of reaction mixture does not change with time. a. Derive the transfer function between inlet concentration of A and outlet concentration of B, and find the ultimate value of outlet concentration of B when inlet concentration is increased to 0.9 kmol/m$^3$. b. The transfer functions of measuring device and control valve are given below. Using Routh Hurwitz criterion, determine the ultimate gain of controller if integral time is 0.1. $G_{ms}(s) = G_v(s) = 1$
