Abstract	There has been an increase in vacuum residue hydroprocessing due to the decrease in fuel oil demand and an increase in distillate demand. Authors describe vacuum residue hydrodesulphurization and hydrocracking processes and their integration with hydrogen networks to evaluate holistic interactions between hydrogen consumers and the hydrogen distribution system. Researchers developed conversion models for sulfur, conradson carbon residue, asphaltenes, and vacuum residue based on the feed quality, catalyst properties, and process operating conditions. They derived a five-lump yield model incorporating a feedstock characteristic index and true boiling points. The results of the model show reasonable accuracy with experimental data. A simultaneous optimization of hydrogen consumer models and the hydrogen network model was executed using the CONOPT solver in the General Algebraic Modeling System environment.
