Abstract

L'invention concerne un système à double voie permettant la capture du CO2 dans des flux à la fois acidifiés et basifiés. Le système peut être incorporé dans une installation autonome en mer pour permettre le fonctionnement de la capture de CO2 océanique plus efficace et rentable. Les systèmes maintiennent des normes environnementales élevées en contenant toutes les solutions acides et alcalines intermédiaires dans un système fermé de telle sorte que l'effluent évacué dans l'océan se trouve à un pH et une salinité similaires à ceux de l'eau océanique d'alimentation, avec seulement le CO2 retiré. L'acide et la base produits par une unité d'électrodialyseur sont utilisés pour obtenir une décarbonisation de l'eau océanique par l'intermédiaire de l'élimination du CO2 gazeux et de l'élimination des précipités solides de CaCO3. Le système est configuré pour nécessiter le traitement d'une très petite fraction de l'admission d'eau océanique totale du processus de génération acide-base.
