    • Processes for the production of chlorine by multi-stage oxidation, for example, by thermal reaction of hydrogen chloride with oxygen using catalysts or by non-thermal activated reaction of hydrogen chloride with oxygen, in which the gas mixture formed in the reaction, comprising the target products chlorine and water, unreacted hydrogen chloride and oxygen, and possibly other secondary constituents, such as carbon dioxide and nitrogen, (a) is cooled to condense hydrochloric acid as an aqueous solution of hydrogen chloride and (b) the aqueous solution of hydrogen chloride formed is separated from the gas mixture, characterised in that (c) the separated aqueous solution of hydrogen chloride is fed at least partially to an electrochemical oxidation in which at least part of the hydrogen chloride is oxidised to chlorine, (d) the chlorine gas occurring in step d) is optionally added to the gas mixture occurring in step c), (e) the residues of water present in the gas mixture from steps c) and e), in particular by washing with sulfuric acid, are removed, (f) the chlorine-rich gas mixture forming is freed of oxygen and optionally of secondary constituents.
    • 通过多级氧化生产氯的方法,例如通过使用催化剂的氯化氢与氧的热反应或通过氯化氢与氧的非热活化反应,其中反应中形成的气体混合物包含 目标产物氯和水,未反应的氯化氢和氧气,以及可能的其他二次成分如二氧化碳和氮气(a)被冷却以盐酸作为氯化氢水溶液冷凝,和(b)氢气水溶液 形成的氯化物与气体混合物分离,其特征在于(c)将分离的氯化氢水溶液至少部分进料至其中至少部分氯化氢被氧化成氯的电化学氧化,(d)氯 步骤d)中发生的气体任选地加入到步骤c)中发生的气体混合物中,(e)来自步骤c)a的气体混合物中存在的水的残留物 (e),特别是通过用硫酸洗涤,除去,(f)形成的富氯气体混合物不含氧气,任选地是二级成分。
