A concentrated liquid biocide composition is produced by a continuous process. The process comprises continuously feeding into mixing apparatus (i) bromine chloride and (ii) an aqueous solution of alkali metal salt of sulfamic acid. These are proportioned to produce an aqueous product having an active bromine content of at least 100,000 ppm (wt/wt), and an atom ratio of nitrogen to active bromine from (i) and (ii) greater than 0.93:1. The desired product which is thus continuously formed, is withdrawn from the mixing apparatus at a rate sufficient to enable the continuous feeding to be maintained. Thus, the withdrawal of the product can be continuous or intermittent, depending upon the type of mixing apparatus being used. In various embodiments of the invention, the bromine chloride is continuously produced from separate feed streams of bromine and chlorine by maintaining such streams under automatic feed rate control whereby the streams are continuously proportioned to come together to form bromine chloride.

Cette composition liquide concentrée biocide est produite par un processus en continu. Le procédé consiste à introduire sans interruption dans un appareil à mélanger, (i), du chlorure de brome et, (ii), une solution aqueuse d'un sel de métal alcalin d'acide sulfamique. Les proportions sont calculées pour produire un produit aqueux dont la teneur en brome actif est d'au moins 100 000 mg/l (poids/poids) et obtenir une proportion de mélange azote/brome actif de (i) et de (ii) supérieure à 0.93/1. Le produit désiré qui est ainsi préparé sans interruption est extrait de l'appareil à mélanger à une vitesse suffisante pour permettre de poursuivre l'approvisionnement en continu. De la sorte, le retrait du produit peut se faire de manière continue ou intermittente selon le type d'appareil utilisé. Dans différents modes de réalisation de l'invention, le chlorure de brome est produit en continu à partir de flux séparés d'alimentation en brome et en chlorure et, dans la mesure où la vitesse de ces flux est maintenue sous contrôle automatique, les proportions de ces flux sont calculées sans interruption, ils sont introduits ensemble dans l'appareil pour former le chlorure de brome.
