MODELING AND SIMULATION OF RISER IN A REFINERY FLUID CATALYTIC CRACKING UNIT
Abstract:
This study focuses on the modeling and simulation of the Fluid Catalytic Cracking Unit (FCCU) riser within the context of Kaduna Refining and Petrochemical Company (KRPC) in Kaduna. The primary function of this unit is to facilitate the conversion of heavy gasoil (VGO) into lighter oils through catalytic cracking, utilizing zeolite as a catalyst. The approach involves gathering operational data and feedstock stream analyses from the KRPC refinery, which are then processed to determine mass fractions of the key species involved in the cracking reactions. A model equation is derived and subsequently simulated using the Comsol Multiphysics software. Both mass and energy balances are conducted. The simulation results from the model exhibit a favorable alignment with experimental outcomes. Additionally, the process yields a gasoline fraction comprising 54% of the total weight. The simulation outcomes closely approximate data from KRPC and other scholarly sources. As a result, the established model holds promise for simulating crude types beyond Nigerian crude, while the employed computational software is endorsed for optimizing process units.
