Modelling and Control of a Diesel Hydrotreating Process

The application of control theories to design the control of a planned or existing process or operation is always performed by blind methods such as trial and error or Zeiglar-Nichols method. The aim of this paper is to apply mathematical models and control theories to design control system of a diesel hydrotreating process. Understanding process dynamics (how process variable change with time) are important to determine the process modeling and process control. In this paper the process dynamics of Diesel hydrotreating unit were explored and reviewed some mathematical tools for solving the resulting process modelling and control.
