Hydrotreating

Metallurgy solution to prevent polythionic acid stress corrosion cracking in hydroprocessing

Hoehn, R. K., Bradley, S. A., Mucek, M. W., Honeywell UOP; Anada, H., Osuki, T., Nippon Steel and Sumitomo Metal Corp.

Hydrotreating is a staple process found in nearly every refinery. The process removes undesirable feed contaminants, such as sulfur, nitrogen and metals, and saturates olefins and/or aromatics to produce high-quality products.

Consider pitot tube pumps for low-flow, high-head applications

Alshaye, A., Saudi Aramco

Low-flow, high-head pumping requirements in refining and petrochemical plants make up less than 2% of the total pump population. This minor percentage is creating significant reliability concerns, which result in low mean-time between failures (MTBF), as well as high maintenance costs.

Production of renewable fuels in existing refinery assets: A cost-effective coprocessing strategy
