Abstract:
(EN) The present invention relates to a high-efficiency hybrid separation process technology using an adsorbent and a separation membrane, which can selectively separate and purify carbon monoxide from industrial byproduct gases, in particular, byproduct gases generated in the iron and steel industry. Specifically, the present invention relates to a process for efficiently separating/recovering high-purity carbon monoxide from other gases existing in byproduct gases contained in steelmaking converter gases which are generated during a steelmaking converter process. The present invention comprises: a pretreatment process for removing impurities such as moisture, metal, and dust from byproduct gases; a membrane separation process for separating byproduct gases including carbon monoxide, carbon dioxide, hydrogen, nitrogen, and the like using a membrane and concentrating carbon monoxide and nitrogen; a process for bringing the gas mixture into contact with an adsorbent to adsorb carbon monoxide; and a desorption process for desorbing carbon monoxide from the adsorbent on which the same is adsorbed.
(FR) La présente invention concerne une technologie de procédé de séparation hybride à haut rendement utilisant un adsorbant et une membrane de séparation, qui peut séparer et purifier sélectivement du monoxyde de carbone à partir de gaz de sous-produits industriels, en particulier des gaz de sous-produits générés dans l'industrie sidérurgique. De façon spécifique, la présente invention concerne un procédé de séparation/récupération efficace de monoxyde de carbone de haute pureté à partir d'autres gaz existant dans des gaz de sous-produits contenus dans des gaz de convertisseur d'aciérie qui sont générés pendant un procédé de conversion d'aciérie. La présente invention comprend : un processus de prétraitement pour éliminer des impuretés telles que l'humidité, le métal et la poussière de gaz de sous-produits ; un processus de séparation par membrane pour séparer des gaz de sous-produits comprenant du monoxyde de carbone, du dioxyde de carbone, de l'hydrogène, de l'azote et similaire à l'aide d'une membrane et concentrer le monoxyde de carbone et l'azote ; un processus pour amener le mélange gazeux en contact avec un adsorbant pour adsorber le monoxyde de carbone ; et un processus de désorption pour désorber le monoxyde de carbone de l'adsorbant sur lequel il est adsorbé.
