In Part 1 of this article, the authors covered techniques for minimizing corrosion and contaminant ingress from condensate return and feedwater to industrial steam generators.
Corrosion is one of the most insidious challenges in the oil refining industry.
Hydrocarbon Processing, the downstream processing sector’s leading technical publication for nearly 100 yr, has announced the finalists for its fifth annual HP Awards, which celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year.
Many heavy industrial plants, such as refineries and petrochemical facilities, require steam for numerous processes, including powering turbines, providing energy for a variety of unit operations and even heating buildings in some locations.
Corrosion under insulation (CUI) is a severe form of localized external corrosion that occurs on stainless steel (SS) that has been insulated.
In this article, the development of a customized program—designed by the author and used at Raffineria di Milazzo—for the continuous monitoring of creep in vessels and piping is explained.
Selecting mechanical seals for hot services in an oil refinery or petrochemical plant is always a challenging task—and it is a task that needs careful attention, since the wrong seal selection can have a significant impact on pump reliability and availability.
Stainless steel is a generic term used for a large group of corrosion-resistant alloys containing at least 10.5% chromium (Cr), and possibly containing other alloying elements like nickel (Ni), molybdenum (Mo), manganese (Mn) and nitrogen (N).
The human factor has played a significant role in chemical plant accidents and production loss incidents over the past 60 yr.
During the end-of-run (EOR) period of the authors’ company’s residue hydrodesulfurization (RDS) process in early February 2019, some hot spots occurred in the catalysts of the reactors.
