    摘要: A method of processing a stream of liquid chlorine containing nitrogen trichloride from a chloralkali plant. The liquid stream is received into a vaporizer in which it is evaporated 1O1 chlorine gas and nitrogen trichloride gas. The gas stream is processed by destroying the nitrogen trichloride gas, for example in a superheater or a catalytic bed. The processed gas stream is recycled to the chlorine production train of the chloralkali plant. The process avoids the use of organic solvents to decompose the nitrogen trichloride and the creation of a waste stream requiring further handling.

    摘要: This invention provides a method for purifying a chlorine supply that includes a chlorine component, a bromine component, and nitrogen trichloride. The method includes the steps of introducing the chlorine supply into a vaporizer, heating the chlorine supply in the vaporizer to form a vapor, and introducing the vapor into a distillation system to provide purified chlorine gas, a distillate that includes liquid chlorine and the bromine component, and a bottoms component including the nitrogen trichloride. The method also includes the steps of condensing the vapor in a reflux condenser, heating the condensate in a reboiler, removing the purified chlorine gas from the distillation system, and removing the distillate from the distillation system.

    摘要: The invention relates to a method for carrying out an optionally catalytically promoted hydrochloric acid oxidation process using oxygen. The method comprises the steps of cooling the process gases in one or more steps and of removing unreacted hydrochloric acid and reaction water from the process gas, of drying the product gases, of removing chlorine from the mixture, and the step of returning the unreacted oxygen to the hydrochloric acid reaction process, at least a part of the caloric content of the product gases being used for heat recovery and at least a part of the coldest gas flows being used in the process for cooling.

    摘要: Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Verwendung von Flüssigchlor als Kältemittel in der Chlorverflüssigung. Ein Teilstrom Flüssigchlor in einer Chlorverflüssigungsanlage wird abgezweigt und einem Verdampfer mit Wärmetauscher zugeführt. Das im Sekundärkreislauf des Wärmetauschers zirkulierende, chlorfreie Kühlmittel kann zur Kühlung in verschiedenen Prozeßstufen innerhalb und außerhalb der Chlorverflüssigungsanlage genutzt werden.
