Model predictive controller design of hydrocracker reactors

Authors: DİLA GÖKÇE

Abstract: This study summarizes the design of a Model Predictive Controller (MPC) in Tüpraş, İzmit Refinery Hydrocracker Unit Reactors. Hydrocracking process, in which heavy vacuum gasoil is converted into lighter and valuable products at high temperature and pressure is described briefly. Controller design description, identification and modeling studies are examined and the model variables are presented. WABT (Weighted Average Bed Temperature) equalization and conversion increase are simulated, results are discussed.

Keywords: Refinery, process control, model predictive control, hydrocracker unit, reactor control
