| Popis: | In this paper, a time-optimal strategy is implemented for batch membrane separation of lactose-salt solution. Parameters of the flow-rate model are estimated by solving a dynamic optimization problem that minimizes the difference between experimental and simulated system outputs. The estimated flow-rate models are used to formulate an optimal control problem (OCP) which minimizes the batch time using diluant addition rate as the control input. This time-optimal strategy is found analytically and is validated using experiments, where lactose is concentrated and concentration of salt is reduced. The processing time is compared with classical industrial strategy to emphasize on the outcomes. |
