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: In a process for extracting (chlorinated) hyrocarbon-free hydrogen chloride and phosgene-free (chlorinated) hydrocarbons from a hydrogen chloride stream containing (chlorinated) hydrocarbons and phosgene, (i) the fresh hydrogen chloride stream containing phosgene and (chlorinated) hydrocarbons is led in a first step first through a first adsorber and then through a second adsorber interconnected in series, until essentially no more (chlorinated) hydrocarbon is adsorbed by the first adsorber; (ii) the fresh hydrogen chloride stream is led in a second step through the second adsorber, while the first adsorber is regenerated, substantially phosgene-free (chlorinated) hydrocarbon being produced during regeneration; (iii) the fresh hydrogen chloride stream is led in a third step first through the second adsorber and then through the regenerated first adsorber, until substantially no more (chlorinated) hydrocarbon is adsorbed by the second adsorber; (iv) the fresh hydrogen chloride stream is led in a fourth step through the first adsorber, while the second adsorber is regenerated, a substantially phosgene-free (chlorinated) hydrocarbon being produced during regeneration, and steps (i) to (iv) can be successively repeated one or more times.

Abstract: The invention relates to a method for recovering ruthenium from a used ruthenium-containing catalyst which contains ruthenium as ruthenium oxide on a carrier material that is difficult to dissolve in mineral acid. Said method comprises the following steps: a) the catalyst containing ruthenium oxide is treated in a hydrogen flow such that the ruthenium oxide provided on the carrier is reduced to metallic ruthenium; b) the reduced catalyst from step (a) containing metallic ruthenium on the carrier material is treated with hydrochloric acid in the presence of an oxygen-containing gas such that the metallic ruthenium provided on the carrier is dissolved as ruthenium(III) chloride and is thus recovered as a ruthenium(III) chloride solution; c) the ruthenium(III) chloride solution from step (b) is further reprocessed if necessary.
