Abstract: The invention relates to a method for the production of chlorine from hydrogen chloride, comprising the steps: a) introducing a hydrogen chloride containing stream a1 and an oxygen containing stream a2 into an oxidation zone with catalytic oxidation of hydrogen chloride to chlorine to give a product gas stream a3 containing chlorine, water, oxygen, carbon dioxide and inert gases, b) bringing the product gas stream a3 into contact with aqueous hydrochloric acid in a phase contact unit with partial separation of water and hydrogen chloride from the stream a3, to give a remaining gas stream b comprising hydrogen chloride, chlorine, water, oxygen, carbon dioxide and, optionally, inert gases, in which gas stream b at least 5% of the hydrogen chloride contained in stream a3 remains, c) drying the gas stream b to give an essentially dry gas stream c, containing hydrogen chloride, chlorine oxygen, carbon dioxide and optionally inert gases, d) partial liquefaction the gas stream c by compression and cooling, to give an at least partially liquefied stream d, e) gas/liquid separation of the stream d into a gas stream e1, containing chlorine, oxygen, carbon dioxide and optionally inert gases and a liquid stream e2, containing hydrogen chloride, chlorine, oxygen and carbon dioxide and optional recycling of at least part of the gas stream ee1 into step a), f) separation of the liquid stream e2 by distillation in a column into a chlorine stream f1 and a stream f2, essentially containing hydrogen chloride, oxygen and carbon dioxide, wherein a part of the hydrogen chloride condenses at the column head and returns into the column to give a stream f2 with a chlorine content

Abstract: The invention relates to a method for producing chlorine by the oxidation of hydrogen chloride with oxygen in a fluidized bed reactor in the presence of a particulate catalyst, the reaction heat produced by the exothermic hydrogen chloride oxidation being carried away by water which circulates in the tubes of a shell-and-tube heat exchanger. The method comprises the following steps: (i) heating the fluidized bed reactor to an operating temperature in the range of 350 to 420°C in a heating phase and (ii) reacting the hydrogen chloride with oxygen at the operating temperature in an operating phase. The method is characterized in that (i-1) the fluidized bed reactor is heated to a temperature below the operating temperature in a first heating phase, and (i-2) hydrogen chloride and oxygen are fed to the fluidized bed reactor and reacted in a second heating phase, the fluidized bed reactor being heated to the operating temperature by the reaction heat produced by the exothermic hydrogen chloride oxidation.
