    • The invention relates to a process and an apparatus for product-conserving thermal dissociation of halogenated aliphatic hydrocarbons, preferably for thermal dissociation of 1,2-dichloroethane to vinyl chloride. This uses chemical dissociation promoters and/or physical measures which initiate the dissociation reaction. The initiation of the dissociation reaction, with the same conversion, lowers the temperature level in the reaction mixture and the temperature of the dissociation gas on exit from the dissociation furnace. The amount and the exit temperature of the flue gas from the radiation zone of the dissociation furnace likewise decrease at the same time. It order to be able to implement the product-conserving mode of operation in the radiation zone of the dissociation furnace and simultaneously to maintain the function of the convection zone, the heat input to the dissociation furnace is divided such that a portion of the heat introduced by underfiring is introduced by burners in the radiation zone, and the other portion of the heat supplied by underfiring is introduced by burners arranged at the exit of the flue gas from the radiation zone.The partial decoupling of the heat input of the radiation zone and of the convection zone makes possible a particularly product-conserving mode of operation.
    • 本发明涉及一种用于产物保存卤代脂族烃的热解离的方法和装置,优选用于1,2-二氯乙烷热解离成氯乙烯。 这使用化学解离启动子和/或引发解离反应的物理措施。 以相同的转化率开始解离反应降低了反应混合物中的温度水平和从解离炉出来的解离气体的温度。 来自离解炉的辐射区域的烟气的量和出口温度同时降低。 为了能够在解离炉的辐射区域中实现产品保存的运行模式,同时保持对流区的功能,将分离炉的热量输入分开,使一部分热量引入 通过燃烧器在辐射区域中引燃,并且由燃烧器供应的热量的另一部分由设置在烟道气出口处的燃烧器从辐射区引入。 辐射区域和对流区域的热输入的部分解耦使得可以实现特别节省产品的操作模式。
