  • Subsurface capture of carbon dioxide
    Patent number: 8783371
    Abstract: A process and apparatus of separating CO2 gas from industrial off-gas source in which the CO2 containing off-gas is introduced deep within an injection well. The CO2 gases are dissolved in the, liquid within the injection well while non-CO2 gases, typically being insoluble in water or brine, are returned to the surface. Once the CO2 saturated liquid is present within the injection well, the injection well may be used for long-term geologic storage of CO2 or the CO2 saturated liquid can be returned to the surface for capturing a purified CO2 gas.
