S6E17 - This is Super Critical! - a podcast by Antoine Walter

Water is a powerful weirdo beyond 374 degrees

Water is the solvent for life. Beyond the statement, this is a chemical truth: water dissolves a variety of molecules, most of the time for the better.

The problem is that it also tends to dissolve a lot of pollutants, which turns wastewater treatment operators crazy when, in turn, they have to separate water from these pollutants.

Now there's good news for them: at 374 degrees and 221 bars, water reaches its critical point. And when it goes beyond that, it totally switches its behavior!

Supercritical water, for instance, rejects salts and minerals that precipitate; and now dissolves organics.

This means that you can also easily dissolve oxygen to trigger a single-phase oxidation that cleans up water in minutes.

And guess what, that reaction is exothermic, which means it produces heat that you can recover to turn your process energy positive.

That's called supercritical water oxidation, and it proves that water is a powerful weirdo beyond 374 degrees!
