Use of Simulation for Optimum Performance of Hydro-desulfurization Unit with ULSD Regulations – An Industry White Paper
The European Union 10-ppm sulfur fuel regulations present various challenges for operating and controlling refinery desulfurization units. Repsol has been using simulation to mitigate some of these challenges. In a joint project with AspenTech, the two companies developed a rigorous steady-state and dynamic Aspen HYSYS® model of Repsol’s Puertollano refinery’s hydrodesulfurization (HDS) unit.
