Beschreibung
Zusammenfassung:	A process and an apparatus for separating and recovering waste alkali from a cyclohexane oxidation solution are provided. A gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.
