Abstract (en)
[origin: DE102006024515A1] Procedure for carrying out an optionally catalyst-supported hydrogen chloride oxidation process in the presence of oxygen, comprises: single or multi-stage cooling of a process gas; separating the non-reacted hydrogen chloride and reaction water from the process gas, drying the product gases and separating chlorine from the mixture, where the process is carried out in a reactor whose structural components that come in contact with the reaction mixture are made of nickel or a nickel-containing alloy. Procedure for carrying out an optionally catalyst-supported hydrogen chloride oxidation process in the presence of oxygen, comprises: single or multi-stage cooling of a process gas; separating the non-reacted hydrogen chloride and reaction water from the process gas, drying the product gases and separating chlorine from the mixture, where the process is carried out in a reactor whose structural components that come in contact with the reaction mixture are made of nickel or a nickel-containing alloy and the proportion of nickel amounts to at least 60 wt.%, preferably from Hastelloy C (RTM: Nickel-chromium-cobalt alloy) (I), Hastelloy B (RTM: Nickel-molybdenum-iron alloy) (II), Inconell 600 (RTM: Nickel-chromium alloy) (III), Inconell 625 (RTM: Nickel-chromium-molybdenum alloy) (IV).
