Table 1

Fourteen variables used for monitoring.

Number	Symbol	Variable
1	TI_Head	Temperature at the head of the distillation column
2	PI_Head	Pressure at the head of the distillation column
3	TI_Above	Temperature above the feed
4	TI_Below	Temperature below the feed
5	TI_Bottom	Temperature at the bottom of the distillation column
6	FI_Vapor	The steam flow
7	FI_Feed	Feed flow
8	FV_ColuHead	Cooling water valve
9	LI_Reflux	Level of reflux
10	FV_Vapor	Vapor valve
11	FV_Reflux	Reflux valve
12	FI_Reflux	Head product flow
13	FV_ Bottom	The bottom of the distillation column valve
14	LI_Bottom	Level at the bottom of the distillation column
