Title
(EN) ENHANCED SORBENT MEMBRANE FOR CARBON DIOXIDE CAPTURE AND METHOD FOR SAME
(FR) MEMBRANE DE SORBANT AMÉLIORÉE POUR CAPTURE DE DIOXYDE DE CARBONE ET SON PROCÉDÉ
Abstract
(EN)
A method for enhancing a sorbent membrane for carbon dioxide capture is disclosed. The method includes applying a layer of a hydrophobic material to at least one surface of the sorbent membrane. The hydrophobic material may be one of a polysioxane, a silicone compound, and a fluoroacrylic copolymer. The sorbent membrane may be an anionic exchange membrane, and may have a quaternary ammonium functional group. The layer of hydrophobic material reduces the amount of water used in the carbon dioxide capture process, and relaxes the water quality constraints.
(FR)
L'invention concerne un procédé d'amélioration d'une membrane de sorbant pour la capture de dioxyde de carbone. Le procédé comprend l'application d'une couche d'un matériau hydrophobe sur au moins une surface de la membrane de sorbant. Le matériau hydrophobe peut être l'un parmi un polysioxane, un composé de silicone, et un copolymère fluoroacrylique. La membrane de sorbant peut être une membrane échangeuse d'anions, et peut avoir un groupe fonctionnel d'ammonium quaternaire. La couche de matériau hydrophobe réduit la quantité d'eau utilisée dans le processus de capture de dioxyde de carbone, et relâche les contraintes de qualité d'eau.
