In this work, we built an integrated optimizing network of ethylene feedstock mutual supply of multisite refinery and petrochemical systems. The optimizing network is developed using a linear programming (LP) model with the objective function of maximizing contribution margin. It could be used to optimize the quantity of ethylene feedstock and subsequent products capacity. The integrated network design specifically addresses ethylene feedstock transmission among the refineries in different locations, and the cracking processing in different ethylene cracking furnaces. The influences of feedstock price and product price on the distribution of mutual raw materials and crude oil are investigated. The method of optimizing ethylene feedstock in this work provides the theoretical guidance for the optimization of chemical continuous processes with an enterprise-wide scale, and the improvement of ethylene feedstock utilization.
