Title
(EN) CO2 SEPARATION & LIQUEFACTION SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE SÉPARATION ET DE LIQUÉFACTION DU CO2
Abstract
(EN)
A CO2 separation and liquefaction system such as might be used in a carbon capture and sequestration system for a fossil fuel burning power plant is disclosed. The CO2 separation and liquefaction system includes a first cooling stage to cool flue gas with liquid CO2, a compression stage coupled to the first cooling stage to compress the cooled flue gas, a second cooling stage coupled to the compression stage and the first cooling stage to cool the compressed flue gas with a CO2 melt and provide the liquid CO2 to the first cooling stage, and an expansion stage coupled to the second cooling stage to extract solid CO2 from the flue gas that melts in the second cooling stage to provide the liquid CO2.

Cette invention concerne un système de séparation et de liquéfaction du CO2, tel qu'il pourrait être utilisé dans un système de captage et de piégeage du carbone pour une centrale électrique brûlant un combustible fossile. Le système de séparation et de liquéfaction du CO2 comprend un premier étage de refroidissement pour refroidir du gaz de combustion avec du CO2 liquide, un étage de compression relié au premier étage de refroidissement pour comprimer le gaz de combustion refroidi, un second étage de refroidissement relié à l'étage de compression et au premier étage de refroidissement pour refroidir le gaz de combustion comprimé avec une masse fondue de CO2 et fournir le CO2 liquide au premier étage de refroidissement, et un étage de détente relié au second étage de refroidissement pour extraire du CO2 solide du gaz de combustion qui fond dans le second étage de refroidissement pour fournir le CO2 liquide.
