From a 2011 presentation ‘Procesy jednostkowe technologii chemicznej’ by Marek Kaźmierczak available on Slideplayer comes this b/w retro-style Sankey:

My Polish is rather limited, but I can see a large stream of sulfuric acid being led in a loop, flue gas cleaning, SO3 absorption

This one was sent to me by Winnie Feng (thanks!). A sample visualization of the vinyl chloride process, but with text in Chinese and English.

The U.S. Department of Energy (DOE), Office of Energy Efficiency & Renewable Energy publishes Sankey diagrams on non process energy on this webiste.

What is non-process energy you might ask. According to DOE, non process energy is “energy used for purposes other than converting raw material into manufactured product. MECS-specified categories of nonprocess energy include facility HVAC, facility lighting, onsite transportation, other facility support (e.g., cooking, water heating), and other nonprocess use.”

You can access the energy flow Sankey diagram for the full U.S. manufacturing sector. Data is from 2010 and flows are in TBtu (Trillion British Thermal Units) per year.

Detailed diagrams on on-site generation, process energy and non-process energy (the three ‘transforming nodes’ in the middle of the full sector) are also presented.

Grey and black arrows show losses. Good work from the Office of Energy Efficiency & Renewable Energy.

I liked the below 3-in-1 Sankey diagram from the e!Sankey website. Actually three different Sankey diagrams of the a steam generation process.

The first is a quantitative (mass) view of the process where water, steam, gaseous emissions are shown in kilograms:

Using the same basic structure, the second shows the energy content within the flows. Values are in MJ. Temperature is shown as additional information with a lighter color.

And finally the temperature only Sankey diagram of the steam generation process. Here the width of the arrows shows the temperature of the steam or gas.

In the background is a transparent technical process diagram of the steam process. Thanks to Michael for providing these Sankey diagrams.

An article on the Polish website ekoenergia.pl titled ‘Rozwój biopaliw – efektywniejsze rolnictwo cz.2’ by Prof. Dr. Włodzimierz Kotowski shows the following Sankey diagram.

The process system shown is a re-esterification of rapeseed oil with methanol. Flows are mass flows shown in kilograms. Methanol is shown in blue. It is re-used and fed back into the process.

Anyone who speaks Polish who can explain further?

Too many colors in the Sankey diagrams posted recently?

Here are two unicolor ones from the Exergy Design Joint Research Lab at Osaka University in Japan. Not that I understand much, but apparently the one at the top is for a gas engine system.

No absolute values given, so just a schematic representation of the flows.

Just before I kick off for a short weekend trip, here is another Sankey for you to enjoy. It is from the Polish language Wikipedia and shows production of KClO3.

This is more of a schematic flow diagram, as it doesn’t show any quantities. The blue boxes are processing steps. Two nice recycling loops in there from the crystalization step back to the electrolysis and from the other crystalization step back to the refining. ‘Szlam’ seems to be sludge. The individual Sankey arrows don’t show an arrow head, but little gray arrows indicate the flow direction from top to bottom.

The whole Sankey just looks kind of odd, because the main product flow is not aligned vertically. But then again, that’s up to the designer. After all, it is a fine sample of a process flow Sankey diagram.
