Prediction of Benzene concentration in a typical distillation column using a modified Fuzzy System

One of the most important and common unit operations in the chemical and petroleum industry isdistillation column. Benzene concentration in the bottom product of distillation column is the desiredvariable to be predicted. The objective of this paper is to design an inferential sensor for estimation ofBenzene concentration in a distillation column.It is shown that the modified fuzzy system can predict the concentration more accurate incomparison with conventional fuzzy system. The fuzzy system that is employed for prediction is Takagi-Sugeno-Kang fuzzy system and the optimization algorithm used for modification is particle swarmoptimization.
