Full textChemical reactors are extensively used in chemical and pharmaceutical industries. The underlying temperature control has shown to be of fundamental importance from product quality and process reproductibility points of view. This thesis presents a control approach to deal with the temperature servo problem in exothermic stirred tank batch reactors. Two features of this research work are worth to be emphasized. The first one consists in an engineering design framework for the control. The underlying design can be performed using various control techniques that heavily borrows from the concepts of prediction, state feedback linearization, sliding mode, backstepping and the high gain. A filtered integral action is incorporated into the design for free offset performance and noise measurements insensitivity considerations. The second one consists in likely high gain observer to perform an accurate estimation of the reaction heat to alleviate the control system performances. The performances the proposed approach are illustrated in a realistic simulation framework with respect to the problem under consideration

Full textThe goal of this thesis is to propose new nonlinear control strategies for the stabilization of perfectly Continuous Stirred Tank Reactors (CSTR). To achieve this goal, we use on the one hand, the entropic thermodynamic approach. More precisely, we use the thermodynamic availability concept and the properties of irreversible thermodynamics to define a Lyapunov function candidate for the stabilization of the closed loop system. We also propose a reduced availability function to design more efficient feedback laws in term of control variable solicitations. On the other hand, we propose an extension of the (pseudo) Hamiltonian formalism associated to dissipative systems to open chemical reactors. We show that the Hamiltonian is linked to the Gibbs free enthalpy in the isothermal case and to ectropy (opposed to entropy) in the non isothermal case. By this formalism, the dissipation of the system represents the irreversible entropy production due to chemical reaction. The Interconnection and Damping Assignment-Passivity Based Control (IDA-PBC) approach is then applied to synthesize feedback laws by choosing the thermodynamic availability as desired closed loop hamiltonian storage function. Finally, we show that feedback laws synthetized by the entropic thermodynamic approach and the pseudo-hamiltonian formulation are equivalent in some cases. Some stabilization properties and the control input admissibility are also considered. Theoretical developments are illustrated on some different CSTR examples : an academic case study and the acid catalyzed hydration of oxirane-methanol to glycerol

Full textIn refining and petrochemistry process safety is a major issue. For highly exothermic processes it is necessary to ensure in a rigorous way the safe that the process operates in safe conditions, hence avoiding thermal runaway. The objective of this thesis was to develop a methodology to determine the operating conditions of reliable operation of chemical reactors. The methodology relies on stationary and dynamic analysis. The stationary stability analysis based on the Van Heerden criterion was generalized to complex chemical systems. The dynamic analysis applies the perturbation theory to definitely determine if a stationary point is stable according to eigenvalue analysis.The methodology was applied to ebullated-bed technology for residue hydroconversion at pilot and industrial scale. Two comprehensive dynamic models that accurately represent the ebullated-bed pilot plant and industrial process were developed for the study. The models take into account a detailed description of the reactive system and the configuration of the pilot and industrial plants: three phases, kinetics and flow characterization. A stationary and dynamic thermal stability analysis was carried out for both configurations and stable/unstable operating regions were identified. The study showed that the pilot plant reactor can operate in a larger domain of operating conditions compared to the industrial reactor while the parameters have the same effect on both reactors. The resulting reactor operation diagrams are a essential guide for engineers in the reactor design and operation practice
