摘要： Disclosed is a process and apparatus for heat recovery in vinyl chloride monomer manufacturing plants or in integrated vinyl chloride monomer/polyvinyl chloride manufacturing plants. A process for capture and use of excess heat recovered in the production of vinyl chloride includes distillatively purifying DCE in a high-boilers column, using a heat exchanger to capture thermal energy from a purified DCE vapor stream from the high-boilers column, generating low pressure steam from the captured thermal energy, returning condensed DCE vapors to the high-boilers column, and heating parts of the plant with the generated low pressure steam.

摘要： The invention is directed to a process and to an apparatus for saving fuel in furnaces for thermal dissociation of halogenated aliphatic hydrocarbons, especially of 1,2-dichloroethane, using chemical dissociation promoters or physical measures which initiate the dissociation reaction.The initiation of the dissociation reaction lowers the temperature level in the reaction mixture with the same conversion. This can also lower the mean firing chamber temperature and save fuel.In a preferred process variant, flue gas leaving the convection zone of the dissociation oven is analyzed and its dew point is calculated. The dew point of the flue gas or the conversion of the dissociation reaction serves as command parameter for the intensity of the physical measure for initiation and/or for the amount of the chemical dissociation promoter added and/or for the amount of fuel.In a further preferred process variant, the latent heat content of the flue gas is used to preheat the burner air or other media.

摘要： 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.

摘要： A process for the preparation of 1,2-dichloroethane that is very pure with respect to chloral or/and chloral hydrate and carbon dioxide is described herein. The process comprises oxychlorination of ethylene, using hydrogen chloride and an oxygen-containing gas, and alkali treatment of the 1,2-dichloroethane produced. In the process, the carbon dioxide present in the 1,2-dichloroethane-containing organic phase is, in accordance with the invention, substantially separated out from the 1,2-dichloroethane-containing organic phase before the alkali treatment.
