The European TOP-REF research consortium has developed and applied a methodology to improve the resource efficiency of industrial production processes. Additionally, a newly developed key resource indicator (KRI) that enables the consideration of material and energy streams in a single indicator—the resource exergy indicator (REI)—has been established. Part 1, published in the January 2019 issue of Hydrocarbon Processing, described the TOP-REF methodology. The following will present its application to three industrial production plants from different industrial sectors: a granular nitrogen, phosphorus and potassium (NPK) fertilizer production plant, a steam cracker plant, and the crude disti
