Project Description
This project focuses on the latest advancements in Fluid Catalytic Cracking (FCC) reactor modeling introduced in Aspen HYSYS versions V14.5 and V15. FCC reactors play a crucial role in petroleum refining by converting heavy hydrocarbons into valuable lighter products such as gasoline and olefins. The new updates aim to improve simulation accuracy, usability, and adaptability for modern refining processes, especially those involving bio-feedstocks.
The upgraded versions introduce enhanced capabilities for modeling complex reactions, including hydro-denitrogenation (HDN) and hydro-desulfurization (HDS), along with improved characterization of bio-feeds containing impurities such as sulfur,nitrogen, andglycerides. The inclusion of dewaxing reactor templates and extended feed libraries enables more realistic simulation of hydro-isomerization and bio-based processes, supporting sustainable fuel production.
Furthermore, the integration of advanced kinetics, increased lumping schemes, and hybrid AI-based calibration techniques significantly enhances the prediction of product yields, particularly for gasoline and light olefins. These improvements make the FCC reactor model more reliable for both conventional and high-conversion refining operations, aligning with modern industry requirements.
