PROCESS FOR DEHALOGENATION OF BRINE

摘要

MD.31421 1. A process for the dehalogenation of a halogen-containing brine in an apparatus comprising (1) a nozzle for converting pressure energy of a liquid into kinetic energy, (2) at least one desorption tube extending from the nozzle and having a gas-tight connection thereto and having an inlet end of the same or of larger crosssectional area than that of the outlet of the nozzle, and (3) a vessel connected to the outlet end of the desorption tube and having a gas-tight connection thereto, the vessel being equipped with means for removing halogen and brine therefrom, the process comprising causing pressurised halogen-containing brine to issue from the nozzle in the form of a jet which diverges downstream of the nozzle and which comes into contact with the entire inner periphery of a part of the desorption tube to seal a totally enclosed space between the jet and the desorption tube, and then to pass to the vessel, and removing from the vessel halogen and dehalogenated brine.
