Optimize Hydrogen Network in Refineries with Rigorous Simulation Tools

Inprocess’ experts detailed in this Oral Contribution how it is possible to save OpEx by minimizing the amount of hydrogen that is sent to the fuel network. An advisory tool, based on an optimizer put on top of a simulation model, is used by operating companies to send the correct amount of hydrogen, at the correct purity,

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.

Alivio de presión en columnas de destilación de crudo

La estimación de los caudales de alivio de presión en la cabeza de las columnas de destilación resulta de cálculo complicado debido a la naturaleza de estas unidades, donde la composición cambia a lo largo de la columna y del tiempo.
