| Abstract: |
| During the oil refining process, oil stain is generated on the contact oil surface of the equipment resulting in a decrease in heat and mass transfer efficiency, while increasing the deodorization temperature will cause a decrease in the quality of the oil. Therefore, it is necessary to clean the deodorization system. The cleaning practice of deodorization systems was introduced in terms of cleaning mechanism, cleaning agent types and cleaning procedure. The deodorization system of oil refinery could be cleaned first by alkali solution and high-pressure water, and then by the professional company with the dissolved detergent. The cleaning effect required oil stain removal rate of more than 95%, no pitting or overwash phenomenon, corrosion rate less than or equal to 1.0 g/(m2·h). In oil refining production, it is necessary to operate and maintain according to operating procedures, and set process control parameters for preventive cleaning. |
