Some Impurities Present In Crude Oil That Can Cause Corrosion
When produced to refinery processing, crude oil possesses many unwanted contaminants. They include sand, inorganic salts, drilling mud, polymer, corrosion byproduct, and many others. Therefore, desalting is required to remove all these impurities before distillation. And you can buy desalter parts to do so. In this blog, we will talk about some of the impurities present in crude oil. Inorganic salts. When inorganic salt gets disintegrated in the crude oil preheat exchangers and heaters, it creates hydrogen chloride gas. Then, it gets compressed to liquid hydrochloric acid at an overhead structure of the distillation column, causing equipment to severely corrode. Iron sulfide and oxide. To prevent breaking down of equipment or corrosion due to salts in the crude oil, you can implement corrosion control. However, the product used to control corrosion of oil field appliances contains particulate iron sulfide and oxide. Condensation of these substances does...
