Real-world data of a deethanizer was utilized to develop a realistic simulation in Aspen HYSYS. The process started with a steady-state simulation, which was meticulously compared to actual operational data to ensure its accuracy. This comparison verified the reliability of the steady-state model, forming a solid foundation for further dynamic simulation where a real-time model was developed to implement the PID controllerenThesis
