Title (EN) DIRECT AIR CAPTURE (DAC) CARBON DIOXIDE (CO2) SEQUESTRATION METHODS AND SYSTEMS
(FR) PROCÉDÉS ET SYSTÈMES DE SÉQUESTRATION DE DIOXYDE DE CARBONE (CO2) À CAPTURE D'AIR DIRECT (DAC)
Abstract:
(EN) Methods of sequestering carbon dioxide (CO2) are provided. Aspects of the methods include contacting an aqueous capture liquid, such as an aqueous capture ammonia, with a direct air capture (DAC) generated gaseous source of CO2 under conditions sufficient to produce an aqueous carbonate liquid, such as an aqueous ammonium carbonate. The aqueous carbonate liquid is then combined with a cation source under conditions sufficient to produce a solid CO2 sequestering carbonate. Also provided are systems configured for carrying out the methods.
(FR) L'invention concerne des procédés de séquestration de dioxyde de carbone (CO2). Des aspects des procédés comprennent la mise en contact d'un liquide de capture aqueux, tel qu'un ammoniac de capture aqueux, une source gazeuse générée de CO2 à capture d'air directe (DAC) dans des conditions suffisantes pour produire un liquide carbonate aqueux, tel qu'un carbonate d'ammonium aqueux. Le carbonate d'ammonium aqueux est ensuite combiné à une source de cations dans des conditions suffisantes pour produire un carbonate de séquestration de CO2 solide. L'invention concerne également des systèmes configurés pour mettre en œuvre les procédés.
