Addressing Product Demand Uncertainty: An Insight into an Ethylene Plant

The present work addresses the simultaneous planning of production and scheduling of the furnaces’ maintenance shutdowns of an ethane-fed ethylene plant under demand uncertainty. The main processing units (eight parallel cracking furnaces) have decaying performance over time due to coke deposition i...
