By taking into account the distribution patterns and typical cases of high-temperature sulfur corrosion in refining equipment mentioned earlier, this corrosion issue can be effectively mitigated through multiple approaches: First, optimize the selection of materials; for high-temperature towers, carbon steel combined with 0Cr13/0Cr18Ni10Ti composite sheets can be used, as these materials offer better corrosion resistance and workability. Cr5Mo material is preferred for pipelines; 321 is used in areas prone to sulfur corrosion, while 316L is used in parts subject to severe erosion such as elbows in oil transfer lines. The heat exchanger tube bundle can be made of aluminum-coated carbon steel or 0Cr18Ni9Ti material to improve resistance to sulfur corrosion. II. Process and Operation Control: Maintain the silicon content in carbon steel at no less than 0.10% to prevent accelerated corrosion of low-silicon steel; simultaneously, keep the medium flow rate below 30 m/s to avoid the scouring and removal of the protective sulfide film. Refer to the McConomy curve (hydrogen-free environment) and the Couper Gorman curve (hydrogen-rich environment) to strictly control the operating temperature, avoiding the peak corrosion rate range of 420–430°C. III. Corrosion monitoring and inspection: With fixed-point thickness measurement as the core method, emphasis is placed on monitoring areas prone to corrosion such as the upper part of horizontal pipelines, furnace tubes, elbows, and joints between different steel types. Used in combination with real-time RT scanning and pulse eddy current technology, it enables the detection of local corrosion without the need to remove the insulation layer, thus providing timely warnings about potential corrosion risks. IV. Auxiliary protection measures: High-temperature corrosion inhibitors are added specifically to form a stable protective film on the metal surface, preventing active sulfur from coming into contact with the substrate. Regular material identification and low-silicon steel inspections are carried out; testing plans are formulated in accordance with standards such as API 939C, and a comprehensive corrosion control system is established throughout the product’s lifecycle.
