In this paper, multiperiod optimization considering safety for an industrial utility plant un-der varying electricity cost, steam demand, and electricity demand have been performed using equation based model. To consider the safety and operation cost simultaneously, quadratic penalty form was introduced. Case study for different steam demands and electric-ity cost for each period have been done, and the optimization results were compared. The result shows that cost can be saved by applying MO and SMO. Comparisons for various characteristics between MO and SMO show that trade-off between optimization of perfor-mance and safety is required for the optimum and safe operation of the process.
