Modeling and Dynamic Analysis of a Fluid Catalytic Cracking Unit (FCCU)

Abstract: This work presents several PSE techniques to analyze the behavior of a FCCU. In the second chapter, the construction of the dynamic model for an Orthoflow F type FCCU is presented. This model only considers the riser, reactor, stripping section, regenerator, slide and interconnection valves. The model can predict, with good accuracy, the yield of gasoline and other products, at the most frequent operating conditions. Parametric sensibility of the model was developed by the Relative Gain Array analysis. A dynamic neural network for the FCCU was proposed using the NARX model in closed loop scheme. The stability of the system was determined using the continuation integration strategy and the stability definition is based in the eigenvalues of the different steady states presented by the unit. Finally, a control strategy was proposed based on the previous analysis made to the unit.
