Preventing Nickel Carbonyl Formation during Hydroprocessing Unit Shutdowns

The potential formation of nickel carbonyl is a hazard for all hydroprocessing units – both hydrocrackers and hydrotreaters. Fortunately, there have not been a lot of incidents in the refining industry related to nickel carbonyl, but there have been fatalities due to nickel carbonyl exposure. This blog will cover the risks of nickel carbonyl exposure, […]
