Abstract

The application provides a simulation method, device and medium for a catalytic cracking whole device, and the method comprises the following steps: performing computational fluid dynamics simulation on a reaction-regeneration system by adopting a virtual full cycle method to obtain a first catalytic cracking reaction-regeneration model; performing order reduction on the first catalytic cracking reaction-regeneration model according to the simulation result of the reaction-regeneration system to obtain a second catalytic cracking reaction-regeneration model; and coupling the second catalytic cracking reaction-regeneration model with a fractionation and absorption-stabilization system to perform joint simulation, and performing process simulation on the catalytic cracking whole device. The computational fluid dynamics simulation of the reaction-regeneration system and the process simulation of the fractionation and absorption-stabilization system are effectively coupled to realize real-time and accurate simulation of the catalytic cracking whole device.
