The tanks holding the initial distillate products from petroleum refining processes suffer severe corrosion
Thread Content
Storage tank for the initial distillate products in petrochemical atmospheric and vacuum distillation units; operating conditions: temperature of 40 degrees, pressure of 0.14 MPa; material: carbon steel. The media are gasoline, oil and gas, and water. Due to corrosion by Cl-H2S-H2O, the metal surface is severely corroded. Such environmental conditions can enable coating the inner wall for corrosion protection.
In this case, it is possible to consider applying a special anti-corrosion coating to the inner wall of the primary product tank. Choose corrosion-resistant coatings that are resistant to chemical corrosion and high temperatures, such as epoxy resin coatings or fluoropolymer coatings; these materials can effectively isolate corrosive chemicals like Cl, H2S, and H2O, protecting the tank from severe corrosion. At the same time, regular inspection and maintenance of the coating to ensure its integrity can effectively extend the service life of the tank. .
Thank you for sharing. The circulating water has white foam; the reason is unknown. https://bbs.hcbbs.com/thread-5669817-1-1.html (Source: Haichuan Chemical Industry Forum). The circulating water in the circulating water system is yellow, similar to the color of the Yellow River. https://bbs.hcbbs.com/thread-5667515-1-1.html (Source: Haichuan Chemical Industry Forum)
