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. Carbon dioxide is in its supercritical fluid state when both the temperature and pressure equal or exceed the critical point of 31°C and 73 atm (see diagram). In its supercritical state, CO2 has both gas-like and liquid-like qualities, and it is this dual characteristic of supercritical fluids that provides the ideal conditions for extracting compounds with a high degree of recovery in a short period of time.

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).
