MATHEMATIC MODELING OF CATALYTIC CRACKING

The catalytic cracking plant is one of the most important facilities in the refinery, due to ensuring the conversion of heavy oil fractions into gasoline, diesel and olefin-rich gases. The catalytic cracking process is a complex process of automatic conduction, due to the strong interactions between the process variables. That is why the mathematical modeling of this process is difficult to achieve, given the nonlinear nature of the system.This complexity increases with the increasingly restrictive requirements regarding the products obtained, the modernization of the installation and especially the reduction of operating costs. The present paper aims to present the techniques of hierarchical management of the catalytic cracking process and the numerical simulation models of this installation.
