Base oil solvent extraction is a critical process in lube oil refining, where undesirable components like aromatics, sulfur, and nitrogen compounds are removed to improve viscosity index, oxidation stability, and overall performance. While the fundamentals of solvent extraction are well-established, optimizing efficiency remains a challenge. Advanced process control (APC) strategies can significantly enhance yield, reduce solvent consumption, and minimize energy costs.

The petrochemical industry is continuously evolving to meet growing demand for cleaner fuels and high-value chemical products. One critical process in refining and petrochemical operations is hydrotreating, which removes impurities like sulfur, nitrogen, and metals from hydrocarbon feedstocks. Integrating hydrotreating units within petrochemical complexes offers significant advantages, including improved efficiency, cost savings, and reduced environmental impact.

Crude oil distillation units (CDUs) are the backbone of refineries, separating crude oil into valuable fractions like naphtha, kerosene, diesel, and residual fuels. However, one of the most persistent challenges in CDUs is fouling—the accumulation of unwanted deposits on heat exchanger surfaces, preheat trains, and distillation columns. Fouling reduces heat transfer efficiency, increases energy consumption, and leads to costly downtime. Implementing effective fouling mitigation strategies is essential to maintain operational efficiency and profitability.
