A Sankey diagram says more than 1000 pie charts
The last weeks have been very busy, so I am just quickly firing off a few more Sankey diagrams from the depth of my hard disk before heading into the holiday season.
This one in German, showing the percentage breakdown of energy flows in a company. Haven’t noted the source, sorry.
Just discovered this new Sankey diagram video via e!Sankey Forum. Apparently just meant as a a show case for the possibilities offered by the e!Sankey software development kit (SDK).
We can see mass flows on a production line with two machines feeding ‘Item A’ and ‘Item B’ into the main production line.
These seem to be hourly flow values over a 30-hour time span. There are some red warnings indicating low buffer, and even one or two times when the production runs dry. Interesting…
Found that there are some more (educational) videos on youtube now that deal with Sankey diagrams.
Dutch tech consulting firm ‘Water and Energy Solutions’ looks at optimization opportunities and cost saving potential in industrial production sites.
Their services offer is advertised with this sample Sankey diagram.
Their approach called “Flux Technology” is a methodology that “first considers a production site at the largest possible scope, focusing primarily on intersecting process and utility streams. At different scope levels we analyze site, plant(s), unit operations, equipment and general operations both qualitatively as well as quantitatively.”
The report about the Material Flows on the Big Island of Hawai’Ii I blogged about a while ago has another Sankey diagram which is interesting and I thought I share this one too.
The diagram shows the input/output flows of material in the Mauna Loa macadamia nut processing plant. Annual production is 3.4 tons.
“From a materials standpoint the plant exhibits an impressive import/export ratio, relying on imports to the island for only a small portion of its total production requirements.”
All flows are in Gg (that’s 10E9 grams, or 1000 tons). Apparently a tiny problem with the recycled biomass loop flows, but otherwise a nice one. Small and trace flows not to scale for good.
