    • PROBLEM TO BE SOLVED: To efficiently recover and recycle carbon dioxide without generating trouble of step in the case where an impregnation treatment is carried out against a large amount of base material by carrying out an impregnation operation in a large amount of supercritical carbon dioxide using a large scale of device. SOLUTION: In the impregnation treatment method for recovering and recycling carbon dioxide, after impregnation substance is impregnated into the base material in supercritical carbon dioxide in an impregnation treatment tank 10, a fluid after the impregnation treatment is introduced to a gas separation tank 30 from the impregnation treatment tank 10 through a pressure reducing valve 20. A liquid or a solid component is removed in the gas separation tank 30 and after the obtained carbon dioxide gas is compressed to make liquefied carbon dioxide or supercritical carbon dioxide, it is stored in a storage tank 60. After the liquefied carbon dioxide or the supercritical carbon dioxide led out from the storage tank 60 is, if necessary, heated or compressed, it is fed into the impregnation treatment tank 10 and the inside the impregnation treatment tank 10 is filled with the supercritical carbon dioxide. Various kinds of improvements are carried out. COPYRIGHT: (C)2004,JPO&NCIPI
    • 待解决的问题:为了在通过在大量的超临界碳中进行浸渍操作对大量的基材进行浸渍处理的情况下有效地回收和再循环二氧化碳而不产生步骤的麻烦 二氧化氮使用大型装置。 解决方案:在用于回收和再循环二氧化碳的浸渍处理方法中,浸渍处理槽10中浸渍物质在超临界二氧化碳中浸渍到基材中后,将浸渍处理后的流体引入气体分离槽 30从浸渍处理槽10通过减压阀20.在气体分离罐30中除去液体或固体成分,并且在所得二氧化碳气体被压缩以制成液化的二氧化碳或超临界二氧化碳之后,储存 如果需要,将从储罐60引出的液化二氧化碳或超临界二氧化碳进行加热或压缩后,进入浸渍处理槽10,浸渍处理槽10内部 充满超临界二氧化碳。 进行各种改进。 版权所有(C)2004,JPO&NCIPI
