As discussed in previous post, Carbon Dioxide (CO2) is known as one of industrial waste gas causing global warming...there are number of measures are implemented to reduce global warming. CO2 reduction measures are CO2 capturing, reinjection into aquifer, injection into reservior for well maintenance, gas injection for enhanced oil recovery (EOR), etc.
Co2 being captured will be injected in the reservior. The injection can be as high as 300-400 atm which is higher than the critical pressure of Co2.
How does Co2 in Supercritical looks like ?
The following image (running in sequence) shows liquid Co2 under pressure boiled and transform itself to supercritical fluid (SCF).
