Abstract: With a method for utilization of the reaction heat that occurs in the production of 1,2-dichloroethane from ethylene, by reaction with oxygen and hydrochloride (oxychlorination), in a fluidized bed reactor, with dissipation of this reaction heat through cooling pipe bundles situated within the reactor, positioned in the fluidized bed, utilization of the heat is supposed to be improved, while simultaneously reducing the size of the corresponding system elements. This is achieved in that part of the reaction heat is dissipated by heating boiler feed water, whereby the heated boiler feed water is used to heat heat sinks in the production process.

Abstract: The invention relates to a method for using reaction heat produced by reaction during the production of 1,2-dichloroethane from ethylene and chlorine in a direct chlorination reactor. The chlorine is produced in a sodium chloride electrolysis and the reaction heat, during the formation of 1,2-dichloroethane is used at least partially for the evaporation of NaOH, which is produced during NaCl-electrolysis for producing the required chlorine for direct chlorination, as a coupling product. The invention also relates to a device for carrying out said method, comprising a multi-tube heat exchanger comprising two fixed tubular plates and a NaOH-liquid phase part, and the caustic soda passes through the inside of the tube and 1,2-dichloroethane passes the outside of the tube. The heat exchanger also comprises devices for feeding and distributing the caustic soda in the inside of the tube.

Abstract: The invention relates to a method for producing high purity 1,2-dichloroethane using a liquid reaction medium that is circulated and that is essentially composed of 1,2-dichloroethane and a catalyst. At least ethylene and chlorine are added to the reaction medium and a mainly chlorine-containing gas flow is dissolved in a part of the reaction medium which is essentially devoid of dissolved ethylene. The gaseous components not dissolved in this solution are removed from the solution by means of a gas-separation device and the solution from which the undissolved gas components were removed is contacted with ethylene which is present in dissolved form.

Abstract: The invention relates to a falling film evaporator, which is fitted with a liquid distributor which is divided into segments, such that it is possible to charge only a limited number of evaporator tubes with liquid and the evaporator can be operated in an optimum manner even with a partial load. The invention also relates to a method for operating said falling film evaporator, the aim of which is to transfer heat, which is released when a gas-vapor mixture is condensed, to a liquid which is to be evaporated at least partially. It would be useful to use said falling film evaporator thus fitted in heat recuperation systems such as those used in the production of 1,2 dichloroethane.
