PROCEDE POUR INTEGRER LA RECUPERATION DES INDICES DE CHLORE A PARTIR D'UN COMPOSE ORGANIQUE CHLORE PAR COMBUSTION AVEC UNE REACTION D'OXYCHLORURATION |
摘要 |
In an integrated process for oxychlorination and combustion of chlorinated hydrocarbons, chlorinated hydrocarbon is burned to recover chlorine values essentially as hydrogen chloride. Hydrogen chloride is recovered from the effluent from the combustion by absorption with aqueous hydrogen chloride. Hydrogen chloride recovered by the absorption is subsequently recovered and employed in an oxychlorination reaction. A gas containing hydrogen chloride, water vapor and some oxygen recovered from the oxychlorination is cooled to condense aqueous hydrogen chloride which is employed in the absorption for recovering hydrogen chloride. The remaining gas is employed in the combustion of chlorinated hydrocarbons. The process has particular applicability to an oxychlorination reaction of the type wherein a molten salt containing the higher and lower valent chlorides of a multivalent metal is contacted with hydrogen chloride and oxygen to recover hydrogen chloride by enriching the higher valent metal chloride content of the molten salt. |
