Abstract: Based on one or more first columns of a table partitioned at a first level over multiple first level partitions, a first partition criteria is evaluated for a data record. Each of the at least first level partitions is further partitioned into a same number of second-level partitions using a same second partitioning method for all first level partitions. One first level partition is identified for storage of the data record, for example by determining the one of the at least two data server processes using the first partition criteria and a first partitioning method that differs from the second partitioning method. Based on one or more second columns of the table, a second partition criteria is evaluated for the data record, and the data record is stored in one of the second-level partitions of the at least two first level partitions.

Abstract: 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.
