The present invention is directed to methods for removing carbon dioxide from air, which comprises exposing solvent covered surfaces to air streams where the airflow is kept laminar, or close to the laminar regime. The invention also provides for an apparatus, which is a laminar scrubber, comprising solvent covered surfaces situated such that they can be exposed to air stream. In another aspect, the invention provides a method and apparatus for separating carbon dioxide (CO2) bound in a solvent. The invention is particularly useful in processing hydroxide solvents containing CO2 captured from air.
L'invention porte: sur un procédé d'extraction de dioxyde de carbone de l'air consistant à exposer des surfaces couvertes de solvants à un courant d'air en régime laminaire ou quasi laminaire; et sur un appareil du type épurateur/laveur présentant des surfaces recouvertes de solvant exposées à un courant d'air; et sur un procédé et un appareil de séparation du CO2 lié à un solvant. Ladite invention s'avère particulièrement utile pour traiter les solvants à base d'hydroxyde contenant du CO2 capturé dans l'air.
