New tools enable refiners to fine-tune refinery configuration and maximize profits

Parihar, P., Kumar, R., Voolapalli, R. K., Agarwal, S., Bharat Petroleum Corp., Ltd.

Moving more distillate streams to diesel production and/or fuel oil (FO) production is a major refining activity. The distillate qualities and quantities, hydrogen price and consumption, product demand and prices, and refinery configuration constraints are key factors for these decisions. Producing higher-quality products from poorer-quality crudes requires more hydroprocessing.1–3 These distillate streams, e.g., heavy kerosine (HK), gasoils (GOs) and light cycle oils (LCOs), etc., are also used as cutter stocks to upgrade vacuum residues (VRs) and downgraded as low-value FO products. FO and VRs are major constrains if no resid-upgrading facilities are available. The heavy distill
