| Abstract: | In accordance with the technical features of PTA solvent dehydration tower,the advanced control and on line optimization system using Honeywell's RMPCT software is implemented.The acid content of top flow and the water content of bottom flow are selected as controlled variables,thus composition of the solvent dehydration tower is kept more constant,and the economic optimization between the acid loss of top flow and stream consumption on the bottom decrease the cost and improve profit. |

| Keywords: | PTA solvent dehydration tower predictive control on-line optimization RMPCT |
