This soft sensor has been applied to the inferential control system of a high purity distillation column.

Preparation of hemellitene (1,2,3-trimethylbenzene) and indene (2,3-dihydroindene) from C_9 aro- matic mixture by mean of precise distillation and cryogenic centrifugal separation was introduced.

By means of precise distillation of the aromatics mixture,the mixture of hemelytron and indene was obtained.

The technique has isomerization of 1,2,4-trimethylbenzen and precise distillation as a union, which is unique and feasible.

They analyzed the superiority of using precise rectification,combined column tray,thermal coupling,process simulation in the field.
