Abstract: Multi-plant heat integration can increase total profits of industrial parks. The relationship among different plants can be regarded as a cooperative coalition. Current researches are mainly focused on recovering waste heat through many inter-plant heat exchangers while ignoring the stability of the multi-plant coalition. When unplanned shutdown occurs, corresponding plants may be unsatisfied with their profits due to those invalid inter-plant exchangers and prefer not to join this multi-plant cooperation. Therefore, there should be a tradeoff between inter-plant heat duties and the stability of the multi-plant cooperation. In this study, Owen-based core constraints are incorporated into a multi-plant direct HEN model to deal with cost savings and coalition stability simultaneously. Two cases compare the financial effectiveness and the profit allocation of our designs with other researches. Results show that the total costs have been reduced and each plant can receive acceptable profits from this multi-plant heat integration under shutdown risks between 0% and 100%.
