Recent developments on sulphur specifications in middle distillate fuels are exerting a higher demand on refinery hydrogen systems. Previous methodologies on hydrogen network optimisation have been developed mainly based on the assumption of fixed hydroprocessing performance with constant...

The importance of exploiting degrees of freedom within a crude oil distillation process for improving energy performance has been a feature of process integration from the earliest days. Combining process changes with changes to the heat recovery system leads to far better results, compared with...

Heat transfer intensification for shell and tube heat exchangers is an efficient technique to increase energy saving when retrofitting heat exchanger networks (HENs). Such intensification has been widely studied in the process industry in recent years from the point of view of individual heat...
