| Abstract: | Delayed coking process is the first method currently used in oil sediment processing industry.By analyzing the mechanism of several corrosions existed in delayed coking construction,such as sulfa corrosion under high temperature,acid corrosion under low temperature,hoop alkylation acid corrosion and erosion,and combined with raw material property and main operating parameters in one delayed coking construction,the material selection scheme for the reform of delayed coking construction was proposed. |
