一种含三氯化铝废油渣的处理及油回收方法
摘要：
本发明公开了一种含三氯化铝废油渣的处理及油回收方法，该方法为：在搅拌条件下，用酸性溶液对含三氯化铝废油渣进行酸化处理，然后静置沉降分层，上层油相经水洗至中性后回收；其中，所述酸性溶液的pH值为0～3，所述酸性溶液与含三氯化铝废油渣的体积比为0.5:1～3:1。本发明采用酸化技术处理含油三氯化铝废油渣，三氯化铝溶于水相中，更不会产生固体颗粒状油块，能够避免酸性三氯化铝废油渣碱中和工艺过程中的固体颗粒状油块产生，进而避免了油水难以分离的现象产生。
摘要（英）：

The invention discloses a treatment and oil recovery method for waste oil residue containing aluminum trichloride. The method includes: under a stirring condition, conducting acidification treatment on the waste oil residue containing aluminum trichloride with an acidic solution, then performing standing settlement for layering, washing the upper oil phase to neutral, and then conducting recovery.Specifically, the pH value of the acidic solution is 0-3, and the acidic solution and the waste oil residue containing aluminum trichloride are in a volume ratio of 0.5:1-3:1. The invention adopts acidification technology to treat the waste oil residue containing aluminum trichloride, after aluminum trichloride dissolves in a water phase, no solid granular oil block is produced, generation of solid granular oil blocks in the alkali neutralization process of acidic aluminum trichloride waste oil residue can be avoided, thereby avoiding the phenomenon of difficult oil-water separation.
