In these challenging times, fluidized catalytic cracking units (FCCUs) aim to improve margins by processing poorer- or different-quality feeds, while maintaining good yield performance.
In these challenging times, fluidized catalytic cracking units (FCCUs) aim to improve margins by processing poorer- or different-quality feeds, while maintaining good yield performance. These feeds may produce more coke and have elevated nitrogen levels, which can then increase the potential for higher cyanides and associated equipment damage in wet hydrogen sulfide (H2S) service.
A general overview of cyanide formation and associated corrosion problems in the catalytic fractionator and gas plant is provided to help explain the nature of the problem and what mitigating actions can be taken. Many FCCUs have no history of cyanide-related problems, as potential cyanide effects are adequately c
