Abstract: Method of concentrating aqueous alkali and apparatus suitable for this purpose. A very energy-saving method of concentrating aqueous alkali originating, for example, from a chloralkali electrolysis plant and an apparatus suitable for this purpose are described. The method/the apparatus utilizes heat of reaction from the formation of 1,2-dichloroethane and includes multistage concentration of the aqueous alkali, where at least part of the heat required for concentrating the aqueous alkali originates from the plant for preparing 1,2-dichloroethane and at least a further part of the heat required for concentrating the aqueous alkali originates from at least one of the higher stages of the plant for concentrating the aqueous alkali and is used for partial heating of the first stage. The apparatus can be used for retrofitting existing integrated plants made up of a DCE plant and chloralkali electrolysis or in the erection of new plants.

Abstract: The invention relates to a method and a device for the optimal use of reaction heat resulting from the production of 1,2-dichloroethane from ethene and chlorine. The aim of the invention is achieved by extracting reaction heat liberated during the reaction of chlorine with ethene and the reaction heat contained in 1,2-dichloroethane. Extraction of said reaction heat from the reaction chamber occurs using at least one part of gaseous 1,2-dichloroethane (latent heat) and at least one part of liquid 1,2-dichloroethane (feelable heat) removed from the reaction chamber. Said reaction heat is used to heat two fractioning columns in order to purify 1,2-dichloroethane of impurities having a boiling point higher than 1,2-dichloroethane.

Abstract: The invention relates to a process and a device for the dissolution of salt that is hardly soluble, especially sodium chloride and other poorly soluble salts in 1,2 dichloroethane, which primarily are to be used in direct chlorination plants for the production of 1,2 dichloroethane. This aim is achieved by mounting an ultrasonic transducer (sonotrode) in the dissolution chamber which is filled with a suspension of salt crystals and 1,2 dichloroethane. The suspension is sent through a filter upon dissolution of the salt.

Abstract: Process and apparatus for producing ethylenically unsaturated halogenated hydrocarbonsThe invention relates to a process and an apparatus for preparing ethylenically unsaturated halogenated hydrocarbons, preferably vinyl chloride by thermal dissociation of 1,2-dichloroethane, using physical or chemical measures which initiate the dissociation reaction.The process/apparatus described makes it possible to increase the amount produced using dissociation reactors of a given size considerably. Use is made here of initiating measures to increase the heat flux through the wall of the reaction tube and at the same time the feed stream and the heating power of the reaction furnace are increased so that the conversion of the reaction is not significantly increased compared to processes without use of initiating measures.To be able to continue to operate the process economically despite the reduction in the reaction temperature, the process parameters have to be set so that at least 50% of the amount of feed used are vaporized by means of the sensible heat content of the reaction mixture leaving the reaction zone.
