结合石油一厂现有糠醛精制装置进行了润滑油加助剂的研究并完成了连续小试实验 ,对精制后的油样进行了相关性质的测定 ,并确定了加助剂后精制过程的最小剂油比。在间歇实验的基础上进行了连续小试实验。结果表明 ,加入少量助剂 ,可以显著降低精制油中的碱氮含量、提高基础油的抗氧化安定性、减少糠醛精制过程中的剂油比及后续精制过程的白土用量 ,而基础油的其它性质基本符合质量要求。这种方法可以提高基础油的收率 ,使精制操作条件变得缓和 ,从而降低装置能耗及操作成本 Combined with the existing furfural refining plant in the first oil plant, the research on lubricant additive and continuous small test were completed. The refined oil samples were tested for their relative properties and the minimum refining process Oil to oil ratio. On the basis of intermittent experiments, continuous small experiment was carried out. The results showed that adding a small amount of auxiliaries can significantly reduce the content of alkali and nitrogen in the refined oil, improve the oxidation stability of the base oil, reduce the ratio of the oil to the oil in the furfural refining process and the amount of white clay used in the subsequent refining process, The basic nature of the quality requirements. This method can improve the yield of base oil, so refined operating conditions to ease, thereby reducing device energy consumption and operating costs
