Mechanistic Dynamic Modelling of an Industrial FCC Unit
نویسندگان
چکیده
The aim of this study is to obtain a model that can simulate the performance of an industrial Fluidised Catalytic Cracking (FCC) unit in steady and dynamic state, and which will subsequently be used in studies of control and real time optimisation. In this paper, a dynamic model for a R2R type FCC unit is presented. The model includes the riser, the stripper/disengager, the regeneration system and the catalyst transport lines. Mass, energy and pressure balances are performed for each of these sections. Simulation results for steady and dynamic states are presented and compared qualitatively with those from previous FCC models.

Dynamic Optimization of a Fcc Converter Unit: Numerical Analysis
Fluidized-bed Catalytic Cracking (FCC) is a process subject to frequent variations in the operating conditions (including feed quality and feed rate). The production objectives usually are the maximization of LPG and gasoline production. This fact makes the FCC converter unit an excellent opportunity for real-time optimization. The present work aims to apply a dynamic optimization in an industr...

A n arti®cial neural network (ANN) model for determining the steady-state behaviour of an industrial Fluid Catalytic Cracking (FCC) unit is presented in this paper. Industrial data from a Greek petroleum re®nery were used to develop, train and check the model. FCC is one of the most important oil re®nery processes. Due to its complexity the modelling of the FCC poses a great challenge. The prop...
