This paper aims to give an understanding of an effect which stabilizes the inlet conditions of compressors for ,supercritical CO2, (sCO2) operating close to the critical point. The effect was observed during testing of the turbomachine within the sCO2-HeRo project, and is caused by the sCO2 real gas ,properties, close to the pseudocritical line.

In a nutshell, supercritical CO2 is used for producing highly-refined CBD isolates. In contrast, ethanol is the go-to when opting for a full-spectrum CBD oil with a wide range of beneficial phytonutrients. Supercritical carbon dioxide (CO2) extraction has exploded in popularity and is arguably the most common choice amongst CBD companies.

In the ,supercritical, state, the density of ,CO 2, will range from 50 to 80% of the density of water. The viscosity of ,supercritical CO 2, is similar as in the gas phase, which can be up to 100 times lower than in the liquid phase. This is quite important for pipeline transport as it implies lower drag.
