Stabilizing Effects of Supercritical CO2 Fluid Properties ...
Stabilizing Effects of Supercritical CO2 Fluid Properties ...

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.

The ,properties, of ,CO2,-rich fluids are particularly relevant to geothermal heat mining using carbon dioxide instead of water. While manometric, volumetric, and gravimetric techniques have been used successfully to investigate adsorption of low-density subcritical vapors, the results have not been satisfactory at higher, liquid-like densities of ,supercritical, fluids.

Carbon capture and storage - Wikipedia
Carbon capture and storage - Wikipedia

Carbon capture and storage, (CCS), or carbon capture and sequestration and carbon control and sequestration, is the process of capturing waste carbon dioxide (,CO 2,), transporting it to a storage site, and depositing it where it will not enter the atmosphere.Usually the ,CO 2, is captured from large point sources, such as a cement factory or biomass power plant, and normally it is stored in an ...

29/5/2019, · ,CO2, that is heated and pressurized into a ,supercritical, fluid (meaning it has ,properties, between a liquid and a gas) can replace steam to drive turbines. Because ,supercritical CO2, transfers heat more efficiently and requires less energy to compress, it results in more electricity production for the same amount of energy input, and reduces the use of water.
