Title (EN) PROCESS FOR GAS SEPARATION BY SOLVENT OR ABSORBENT
(FR) PROCÉDÉS ET APPAREILS DE SÉPARATION DE GAZ PAR SOLVANT OU ABSORBANT
Abstract:
(EN) Solvent absorption processes for separating components of an impure feed gas are disclosed. The processes involve two stages of gas purification. The acid gases including hydrogen sulfide, carbon dioxide and other sulfur compounds are simultaneously removed from the feed gas by contact with a physical solvent in two stages. The subject matter disclosed provides improved processes to reduce the operating costs of the system.
(FR) L'invention concerne des procédés d'absorption par solvant permettant la séparation de constituants d'un gaz d'alimentation impur. Les procédés impliquent deux étapes de purification de gaz. Les gaz acides comprenant du sulfure d'hydrogène, du dioxyde de carbone et d'autres composés soufrés sont simultanément éliminés du gaz d'alimentation par contact avec un solvant physique en deux étapes. L'invention concerne également des procédés améliorés pour réduire les coûts de fonctionnement du système.
