The Dynamic Behavior and Control of Absorption Column

The present paper deals with studying the dynamic model and control of absorption column by implementing two types of control strategies for CO2 gas and NaOH solution. The control methods in this study are PID, fuzzy with five membership function. The results showed that a good improvement   for CO2/Air-NaOH system with chemical reaction is achieved when the fuzzy logic with five membership function because these methods have more suitable, lower over shoot, less offset value and less integral absolute error.
