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


The effect of process variables on the recovery of hardness from water byacation exchanger was studied. At steady state the process could be represented bysecond order nonlinear emperical model. Although this model was less accurate thanthe dynamic model,the results show agreement when compared with the experimentaldata. The steady state optimization model was used to limit the operating conditions ofthe system. The static feed forward control could be used with the aid of on – linedigital computer.
