    摘要： 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.

    摘要： The invention provides a method for purifying MTO quench water and scrubbing water via mini-hydrocyclone separation, comprising: removing the entrapped catalyst particles from the MTO quench water via mini-hydrocyclone separation; cooling the quench water purified by mini-hydrocyclone separation so as to effect the recycling of water; removing the entrapped catalyst particles from the MTO quench water to be stripped via mini-hydrocyclone separation, so as to reduce the deposition of the catalyst particles within the stripping tower; removing the entrapped catalyst particles from the MTO scrubbing water via mini-hydrocyclone separation; and cooling the scrubbing water purified via mini-hydrocyclone separation so as to effect the recycling of water. The invention also provides an apparatus for purifying MTO quench water and scrubbing water via mini-hydrocyclone separation.
