Abstract:
(EN) The present invention provides a method for collecting carbon dioxide and recovering hydrogen from steelmaking byproduct gas. A method and apparatus for collecting carbon dioxide and recovering hydrogen from steelmaking byproduct gas according to the present invention have the advantages in that by using a hollow fiber separating membrane and an absorbent the process is simpler than the prior art technology, the apparatus can be made smaller, and the apparatus has low installation and operating costs, etc. In addition, even in the case of gas which has not undergone a water-gas shift (WGS) reaction and contains moisture and other impurities, carbon dioxide can be stably separated and hydrogen can be recovered, thus providing the advantages in that the burden of pretreatment is low and energy efficiency is high.
(FR) La présente invention concerne un procédé de collecte de dioxyde de carbone présent dans un produit secondaire gazeux d'élaboration de l'acier, et de récupération d'hydrogène. Un procédé et un appareil de collecte de dioxyde de carbone présent dans un produit secondaire gazeux d'élaboration de l'acier, et de récupération d'hydrogène selon la présente invention présentent les avantages en ce que le procédé est plus simple que la technologie de l'état de la technique mise en œuvre par l'intermédiaire d'une membrane de séparation à fibres creuses et d'un absorbant, l'appareil peut être de taille réduite, l'appareil présente de faibles coûts d'installation et de fonctionnement, etc. De plus, même dans le cas d'un gaz qui n'a pas subi de réaction du gaz à l'eau (WGS) et qui contient de l'humidité et d'autres impuretés, du dioxyde de carbone peut être séparé de manière stable et de l'hydrogène peut être récupéré, fournissant ainsi les avantages en ce que la charge se rapportant au prétraitement est faible et l'efficacité énergétique est élevée.
(KO) 본 발명은 제철 부생가스로부터 이산화탄소 포집 및 수소 회수 방법을 제공한다. 본 발명에 따른 제철 부생가스로부터 이산화탄소 포집 및 수소 회수 방법 및 장치는 중공사 분리막과 흡수제를 통해 종래 기술보다 공정이 단순하고, 소형화 할 수 있으며, 낮은 설치비 및 운전 비용 등의 장점이 있다. 또한, 수성가스 반응(WGS)을 수행하지 않은 수분 및 기타 불순물이 함유되어 있는 가스의 경우에도 안정적으로 이산화탄소를 분리할 수 있고, 수소를 회수할 수 있어 전처리의 부담이 적고 에너지 효율이 높은 장점이 있다.
