Simulation and control of evaporator: caustic soda concentrate

Abstract

The presented work examines the dynamic model as well as the control related to the multiple-effect evaporator through conducting 3 control strategy types for the evaporation of the caustic soda solution. Neural, fuzzy, and PID are the control techniques in this work, while the results specified that excellent enhancement for caustic soda system was done in the case when a fuzzy logic with 7 functions of membership and neural predictive control was utilized, since such approaches were more adequate, less integral absolute error, less offset value and low overshoot
