Dynamic Simulation of FCCU under Abnormal Condition

Abstract:

The dynamic mathematical model of FCCU reactor was established. Reaction kinetics uses five parameter lumped model, with components emulated by similar hydrocarbons. Simulation system was built to simulate normal conditions, and the effect of some abnormal conditions on charred tank’s exit oxygen content, charred tank’s temperature (not cooled), charred tank’s temperature (cooled) were studied. Because the abnormal condition is the combustion of regenerator’s dilute phase’s extremity, this paper used the amount of carbon monoxide’s combustion to simulate this abnormal condition.With the variation of the charred tank’s exported oxygen content or temperature reflects the degree of dilute phase’s combustion. The results show that the dynamic simulation of the system can accurately simulate the cracking reactor abnormal condition.
