Modeling and Simulation of Reaction and Fractionation Systems for the Industrial Residue Hydrotreating Process

4. Workflow of Developing an Integrated Residue Hydrogenation Process Model

The workflow for developing an integrated residue hydrogenation model is shown in Figure

5

with the Aspen HYSYS

/Refining simulation software. A similar workflow for the hydrocracking

process was proposed in [

24

]. However, it is di

fferent for the heavy petroleum refining process.
