    • A method for producing an ultra-pure gas, having an ultra-pure gas producing process comprising the steps of refining a pre-refined raw material fluid in a first refining column (10), and guiding the obtained high-purity fluid to a second refining column (20) for further refining, characterized in that part of a reflux liquid closer to a column top than to a raw material supply section in the first refining column (10) is guided to the column top of the second refining column (20) while regulated in flow rate to form its reflux liquid, and, while gas in the column top is sent back to the column top of the first refining column (10), an ultra-pure substance is recovered from the refining section (21) or the column bottom of the second refining column (20), thereby providing a method for producing an ultra-pure gas and a device therefor which are simple in device construction and advantageous in costs and which can maintain a purity of an ultra-pure gas at a high level.
    • 一种制造超纯净气体的方法,具有超纯气体的制造方法,其特征在于,在第一精制塔(10)中精制预精制原料液,将得到的高纯度流体引导到第二精制塔 精炼塔(20)进一步精制,其特征在于,将第一精馏塔(10)中比原料供应部分更靠近塔顶的部分回流液体引导至第二精馏塔(20)的塔顶 ),同时以流量调节以形成其回流液体,并且当塔顶中的气体被送回到第一精炼塔(10)的塔顶时,从精炼部分(21)回收超纯物质, 或第二精炼塔(20)的塔底,从而提供一种制造超纯气体的方法及其装置,其装置结构简单,成本有利,并且可以保持超纯气体的纯度 在高层。
