    Abstract: A detergent composition for the floor of a clean room is provided to allow the pollution source to be removed easily by lowering surface tension, to prevent the recontamination by having a large contact angle to the water on the surface of floor after cleaning and to reduce the generation of bubbles. A detergent composition for the floor of a clean room comprises a fluorinated alkyl glycerin derivative represented by the formula 1, wherein Rf is a C2-C8 alkyl group substituted with at least one a fluorine atom (F). Preferably the composition comprises 0.01-0.1 wt% of the fluorinated alkyl glycerin derivative; 0.5 - 1.0 wt% of a nonionic surfactant; 1 - 5 wt% of an alkylene oxide adduct; 0.01 - 0.05 wt% of a cationic surfactant; and the balance of water.

    Abstract: 이산화탄소, 질소, 일산화탄소 및 수소를 포함하는 산업부생가스를 공급하는 공급부; 이산화탄소 및 수소를 투과시킬 수 있는 분리막을 포함하며, 상기 공급부로부터 공급되는 산업부생가스를 공급받아 이산화탄소 및 수소를 투과시키는 제1 막분리부; 및 전이금속이 담지된 고분자막을 포함하며, 상기 제1 막분리부에서 잔류한 기체를 공급받아 일산화탄소를 투과시키는 제2 막분리부;를 포함하는 산업부생가스로부터 일산화탄소 회수 시스템이 개시된다. 본 발명의 일 측면에 따른 일산화탄소 회수 시스템은 별도의 원료와 부원료 및 열에너지가 사용됨이 없이 상온에서 오직 압력 조작만으로 산업부생가스로부터 일산화탄소를 고순도로 회수할 수 있으므로 분리비용이 적게 들고, 공정이 간단하여 투자비 또한 적게 들며, 부수입을 올릴 수 있는 액화 CO
    2 도 얻게 되므로 경제성이 높다는 이점이 있다.
