Abstract
The ethylene production process and feedstock management are critical activities in an olefin plant. Analysis of these two problems makes possible better use of the plant feeding material and enhanced production capabilities.
Authors develop an innovative, synchronized decision-supporting framework for long-term planning and scheduling in an ethylene plant by simultaneously considering upstream naphtha inventory management and downstream ethylene furnace operation with a sub-cooperative model. The model also incorporates more logistic and operational characteristics of the sub-problems in practice. The efficacy and the economic potential of the proposed integration framework are illustrated through a comprehensive case study from the real world ethylene plant.
