  • Boundary value problems involving continuous flow reactors have been considered in which tubular reactors have been modeled with an axial dispersion model. Concentration distribution in tubular reactors can have variety of consequences. It can have negative effects on the conversion and selectivity of the desired reaction. Consequently, it will affect the productivity and energy efficiency of the plant. It is therefore important to design efficient controllers that are able to track the optimal pre-defined trajectories of the operating conditions to ensure optimal operation of the reactor. The governing transport phenomena occurring in a tubular reactor is modeled by parabolic partial differential equations (PDEs). In this work, infinite dimensional optimal control of a tubular reactor is studied which is discretized exactly over time, without any discretization over space. The discrete case is derived from the continuous case and the process is shown theoretically. Numerical simulations are performed for formulated optimal controller and its performance is studied.
