Abstract: In this paper we extend upon our previous work on the deterministic design of an optimal network for the integration of multisite refinery and petrochemical systems to incorporate uncertainty. A two-stage stochastic mixed-integer program with the objective of minimising the refining cost over a given time horizon and maximising the added value by the petrochemical network is proposed in this paper. Uncertainties considered in this study are in terms of imported crude oil price, refinery product price, petrochemical product price, refinery market demand, and petrochemical lower level product demand. The proposed method adopts the sample average approximation (SAA) method for scenario generation and optimal gab statistical bounding. The model performance is tested on an industrial case study of multiple refineries and a polyvinyl chloride (PVC) complex.
