Data-driven multi-period modeling and optimization for the industrial steam system of large-scale refineries
CHEMICAL ENGINEERING SCIENCE(2023)
Abstract
•A novel steam system model with periodic process steam demand is established.•The optimized model is proposed according to CO2 emission and outsourced steam.•Uncertainty of equipment failure is discretely classified into three scenarios.•Three cases of a real refinery are explored based on the proposed model.
