Optimization and Control of Acation Exchanger :1- Steady State Optimization

The effect of process variables on the recovery of hardness from water by acation exchanger was studied. At steady state the process could be represented by second order nonlinear emperical model. Although this model was less accurate than the dynamic model,the results show agreement when compared with the experimental data. The steady state optimization model was used to limit the operating conditions of the system. The static feed forward control could be used with the aid of on – line digital computer.
