This study measures the resource efficiency of a basic oxygen steelmaking plant and develops visual maps of its resource use using raw energy and material data extracted directly from the control system. Resource efficiency is measured in units of exergy and resource flows are visualised in Sankey diagrams. Both the metric and the visuals are computed in close-to-real time scales, and are presented...
Currently the metrics used to compare plants and to define how well these use resources take the form of energy intensities or yields. Both of these ignore the physical value of material by-products and focus separately on a single resource. A resource efficiency metric is proposed, measured in exergy, as a tool to more holistically compare the efficiency with which industry consumes energy and materials...
