| 中文摘要: |
| 在油脂精炼过程中设备触油表面会产生油垢，导致传热传质效果下降，而提高脱臭温度会造成油脂质量下降，因此需要对脱臭系统进行清洗。从清洗机制、清洗剂种类、清洗程序等方面介绍了脱臭系统的清洗实践。油脂精炼厂清洗脱臭系统可先采用碱液和高压水冲洗，再请专业公司采用溶解性清洗剂进行清洗，清洗效果要求被清洗的金属表面除垢率大于95%、无点蚀及过洗现象、腐蚀率小于或等于1.0 g/(m2·h)。 在油脂精炼生产中需按照操作规程进行操作和维护，设置好预防清洗的工艺控制参数。 |
| 英文摘要: |
| 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. |
