Title (EN) METHODS AND SYSTEMS FOR GAS SEPARATION
(FR) PROCÉDÉS ET SYSTÈMES DE SÉPARATION DE GAZ
Abstract:
(EN) Systems and methods for gas separation are disclosed. In one exemplary embodiment, a method for gas separation includes the steps of contacting a feed gas stream that includes a product gas and an impurity gas with a liquid-phase absorption solvent and absorbing the impurity gas and a portion of the product gas of the feed gas stream into the liquid-phase absorption solvent. The exemplary method further includes the steps of subjecting the liquid-phase absorption solvent to a first reduced pressure environment to remove the portion of the product gas and a portion of the impurity gas from the liquid-phase absorption solvent and separating the portion of the product gas from the portion of the impurity gas.
(FR) L'invention concerne des systèmes et procédés pour la séparation de gaz. Dans un mode de réalisation donné à titre d'exemple, un procédé de séparation de gaz comprend les étapes consistant à mettre en contact un courant gazeux d'alimentation qui comprend un produit gazeux et une impureté gazeuse avec un solvant d'absorption en phase liquide et à absorber l'impureté gazeuse et une partie du produit gazeux du courant gazeux d'alimentation dans le solvant d'absorption en phase liquide. Le procédé donné à titre d'exemple comprend en outre les étapes consistant à soumettre le solvant d'absorption en phase liquide à un premier environnement à pression réduite pour éliminer la partie du produit gazeux et une partie de l'impureté gazeuse du solvant d'absorption en phase liquide et séparer la partie du produit gazeux de la partie de l'impureté gazeuse.
