  • Method and system for extracting carbon dioxide by anti-sublimation at raised pressure
    Patent number: 8163070
    Abstract: A method for removal of CO2 from a gas stream by anti-sublimation, comprising the steps of: a) introducing a gas stream containing CO2 into a frosting vessel; b) reducing the temperature of at least a portion of the gas stream in said frosting vessel to a temperature at which solid CO2 is deposited by anti-sublimation; c) discharging the gas stream depleted of CO2 from the frosting vessel; and d) recovering the deposited solid CO2; wherein the pressure of the gas stream in step b) is higher than atmospheric pressure. An anti-sublimation system for removal of CO2 from a gas stream, comprising: a frosting vessel configured to receive the gas stream, said frosting vessel comprising a low temperature refrigeration device configured for reducing the temperature of at least a portion of a gas stream in said frosting vessel to a temperature at which solid CO2 is deposited by anti-sublimation; and a compressor configured to increase the gas pressure of the gas stream which is fed to the frosting vessel.
