摘要： The invention relates to a method for producing chlorine by the thermal reaction of hydrogen chloride with oxygen using catalysts and/or by the non-thermally activated reaction of hydrogen chloride with oxygen, in which a) the gaseous mixture produced during the reaction, consisting at least of the target products chlorine and water, non-converted hydrogen chloride and oxygen, additional minor constituents such as carbon dioxide and nitrogen and optionally phosgene, is cooled to condense hydrochloric acid, b) the liquid hydrochloric acid thus produced is isolated from the gaseous mixture, c) the residual water in the gaseous mixture is removed, in particular by washing with concentrated sulphuric acid. The method is characterised in that d) oxygen and optionally also minor constituents, in particular CO 2 and/or N 2 are eliminated from the resultant gaseous mixture by gas permeation.

摘要： The invention relates to a three-stage method for recovering chlorine from a waste-gas stream containing chlorine. According to said method, in a first stage A) the waste gas stream is compressed, in a second stage B) the waste gas stream resulting from the first stage is cooled and the chlorine contained therein is partially or completely isolated by condensation, together with some of the other condensable or soluble components contained in the gas and the condensate obtained is brought into contact with the waste gas stream entering the second stage in counter-current in a gas-liquid contact zone lying beneath the condensation zone. In a third stage C), the condensate exiting the second stage is separated in a rectification column into a chlorine-rich bottom stream and a gaseous and a liquid head stream that are chlorine-lean. The chlorine-rich bottom stream is reprocessed to obtain chlorine.
