The complexity of controlling corrosion in refining equipment and pipelines intensifies as the industry embraces low-carbon fuels. Co-processing vegetable oils with crude fractions introduces new risks, particularly in hydrotreating units where the oxygen in fatty acids generates water, carbon monoxide, and carbon dioxide. These components, alongside chlorides, can cause significant corrosion, especially in systems not originally designed for such conditions.
To combat these challenges, engineers must adapt their materials and processes. Download the paper for:
