    • A process for the removal of chlorine from a gaseous mixture comprising chlorine gas and carbon dioxide gas, which comprises feeding an aqueous solution or suspension containing an alkali metal sulfite and/or an alkaline earth metal sulfite and optionally an alkali metal hydroxide and/or an alkaline earth metal hydroxide in a proportion not greater than twice in molar ratio the alkali metal sulfite and/or alkaline earth metal sulfite, and washing the gaseous mixture with the solution or suspension while controlling the pH of the solution or suspension within a range of 1.9-6.3, whereby chlorine is solely removed from the gaseous mixture.
    • 将含有氯,二氧化碳和不可冷凝气体的气体混合物(531)压缩(501)并冷却(502)以将其分离成主要由不可冷凝气体主要部分形成的残余气体, 主要由氯形成的冷凝物。 将冷凝物供给到汽提塔(505)以解吸二氧化碳和少部分溶解在冷凝物中的不可冷凝气体。 主要由氯和二氧化碳形成的汽提气体可以进一步处理。 即,将汽提的气体与残留气体混合。 将混合气体的至少一部分进料到吸收塔(512)中,由此大部分残留的氯被吸收以降低氯含量。 可以通过用含有碱金属亚硫酸盐和/或碱土金属亚硫酸盐的水溶液或悬浮液洗涤(525)同时控制pH值从而从上述方法的这种气体混合物或废气中除去氯 溶液或悬浮液在1.9-6.3的范围内。

    • The present invention provides an industrial concentration/purification method and apparatus in which hydrogen chloride in a arterial gas containing hydrogen chloride is oxidized to obtain a produced gas containing chlorine, and this chlorine is then concentrated/purified mainly by the use of a pressure swing adsorption process.
      According to the present invention, there are provided a high-yield and non-environmental pollution type high-purity chlorine preparation method and apparatus by which the produced gas containing chlorine can be obtained from the material gas containing hydrogen chloride with a high oxidizing reaction conversion, and a high-purity concentrated/purified chlorine gas and a treated waste gas scarcely containing the chlorine gas can be obtained from the produced gas containing impurities.
    • 本发明提供了一种工业浓缩/净化方法和装置,其中将含有氯化氢的动脉气体中的氯化氢氧化以获得含氯的产生气体,然后主要通过使用变压吸附法将该浓缩/纯化 处理。 根据本发明,提供了一种高产率和非环境污染型的高纯度氯制备方法和装置,通过该方法和装置,可以从含有氯化氢的材料气体以高氧化反应转化率获得含氯气体 并且可以从产生的含杂质的气体中获得高纯度浓缩/纯化氯气和几乎不含氯气的处理废气。

    • The invention concerns a method for producing chlorine and a hydrochloric gas including the following steps: a) supplying via a stream containing hydrochloric gas (a1) and a stream containing oxygen (a2) an oxidation zone and a hydrochloric gas catalytic oxidation with chlorine, a stream of gaseous product (a3) containing chlorine, water, oxygen, carbon dioxide, and the inert gases obtained; b) cooling the stream of gaseous products (a3) and separating the water from the hydrochloric gas in the form of hydrochloric acid, a gas stream (b) containing chlorine, water, oxygen, carbon dioxide, and the inert gases still remaining; c) optionally drying the gas stream (b), and obtaining a gas stream (c) substantially water-free, containing chlorine, oxygen, carbon dioxide and inert gases; d) liquefying at least partly the gas stream (c) and a return stream (f1) rich in chlorine, containing chlorine, oxygen, carbon dioxide through thickening and cooling, a partly liquefied stream (d) being preserved; e) gas-liquid separation of the stream (d) into a gas stream (e1) containing chlorine, oxygen, carbon dioxide, and inert gases and into a liquid stream (e2) containing chlorine, oxygen, and carbon dioxide; f) introducing at least part of the gas stream (e1) into a unit with membrane and separating a return stream (f1) rich in chlorine and a gas flow (f2) poor in chlorine, containing chlorine, oxygen, carbon dioxide, via a separation by the membrane and reintroducing the return flux (f1) rich in chlorine in step d); g) separating the liquid stream (e2) by distillation into a stream of chlorine (g1) and a stream (g2) comprising substantially oxygen and carbon dioxide.
