Abstract

Un système de captage direct de l'air pour le captage du dioxyde de carbone (CO2) à partir de l'air atmosphérique comprend au moins une paroi de contacteur, un système de distribution de liquide et un système de régénération en communication fluidique avec le système de distribution de liquide. Ladite au moins une paroi de contacteur comprend une pluralité de contacteurs gaz-liquide disposés côte à côte. Chaque contacteur gaz-liquide de la pluralité de contacteurs gaz-liquide comprend un boîtier, au moins une entrée, au moins une sortie, au moins une section de garnissage disposée entre ladite au moins une entrée et ladite au moins une sortie, et un ventilateur. Le système de distribution de liquide comprend au moins un dispositif de collecte de liquide. Ledit au moins un dispositif de collecte de liquide comprend un collecteur de liquide inférieur qui comportant un fond positionné sous les sections de garnissage de la pluralité de contacteurs gaz-liquide, et une pluralité de parois s'étendant vers le haut depuis le fond.
