Let's consider a simple example of a model of a plug flow reactor that is described by a system of ordinary differential equations. A plug flow reactor is operated as shown in Figure (9.1) below. A A-k »B- >C C z=0 z-3 Figure (9.1) Isothermal plug flow reactor The plug flow initially has only reactant A, the components A react to form component B. The mole balance for each component is given by the following differential equations dC, =-k,C, dz dC = k,C - k,CB dz dC. = k,C, u dz With the following initial values CA (Z=0) =1 kmol/m³ Св (2-0) -0 Cc (z=0) =0 and k=2 k2=3 If u=0.5 m/s and reactor length z=3 m. Solve the differential equations and plot the concentration of each species along the reactor length
