Diesel hydrotreating units (HDUs) play a critical role in removing sulfur, nitrogen, and aromatic compounds from middle distillates to meet stringent environmental regulations. Central to their performance is the catalytic bed—commonly comprised of CoMo or NiMo catalysts supported on γ-alumina—which progressively loses activity over time.

Economic Viability of HFO Visbreaking in Low-Sulfur Fuel Oil (LSFO) Markets
The global shift toward low-sulfur fuel oil (LSFO) due to IMO 2020 regulations has significantly altered refinery economics, pushing refiners to optimize residue upgrading processes. One such technology, visbreaking, offers a cost-effective solution for converting heavy fuel oil (HFO) into lighter, more valuable products while adjusting to LSFO demand. But how economically viable is visbreaking...

Comparative Analysis: Ultrasonic Oxidative Desulfurization vs. Hydrodesulfurization (HDS)
The global push for cleaner fuels has intensified the need for efficient desulfurization technologies. Two prominent methods—Ultrasonic Oxidative Desulfurization (UOD) and Hydrodesulfurization (HDS)—have emerged as key players in reducing sulfur content in fuels. While both aim to achieve the same goal, their mechanisms, efficiency, and environmental impacts differ...

The Role of Temperature Control in Solvent Extraction for Base Oil Production
Solvent extraction is a critical process in the production of high-quality base oil from waste oil. It involves using selective solvents to separate desirable lubricating oil fractions from impurities such as waxes, asphaltenes, and other contaminants. One of the most crucial factors influencing the efficiency and effectiveness of this process is temperature control. Proper temperature...
