Production of Supercritical Carbon dioxide

Question

this must be the third time I have posted this, I don't mean to keep asking it, it's just that no one is answering...

Does anyone know the industrial production of supercritical carbon dioxide? And how to maximize it's yield in the industry?

I think it may have something to do with it being a byproduct of many things, but what things? and how is it made in the thing that it is a byproduct of?

Thank you to anyone that can help

Answer 1

supercritical carbon dioxide is obtained by increasing both its temperature and pressure beyond carbon dioxide's critical points (31.1°C and 72.9 atm).

I hope that helps!
