Abstract: The corrosion often happens to the tubes of air pre-heaters in hydrocracking plants and blocks air pre-heaters so much, that the circulative effect is not well. A kind of cleaning method is developed against the frequent blocking of the air pre-heater after a deep analysis. The chemical cleaning effect proves that the analysis is right. It saves funds for the plant, and resolves problems with production.
