The present invention relates to process to prepare a chlorine-containing compound using an aqueous salt solution containing at least 100 g/l of sodium chloride and a contaminating amount of polyvalent cations comprising the steps of (i) preparing an aqueous salt solution containing at least 100 g/l of sodium chloride and at least 0.01 ppm of polyvalent cations by dissolving a sodium chloride source in water, (ii) adding an effective amount of at least one positive retention enhancing component to the aqueous solution, (iii) subsequently subjecting the solution to a nanofiltration step, thereby separating the solution into a retentate which is enriched for polyvalent cations and a permeate which is the purified aqueous salt solution, (iv) reacting the chloride anions in the permeate to a chlorine- containing compound by an electrolysis step, and (v) recycling at least part of the retentate to dissolution step (i).
Procédé d'élaboration de composé contenant du chlore par le biais d'une solution saline aqueuse contenant au moins 100 g/l de chlorure de sodium et une quantité contaminante de cations polyvalents (i) élaboration d'une solution saline aqueuse contenant au moins 100 g/l de chlorure de sodium et au moins 0,01 ppm de cations polyvalents par dissolution de source de chlorure dans de l'eau industrielle, (ii) adjonction de quantité efficace d'au moins une composante d'augmentation de rétention positive à la solution saline aqueuse, (iii) nanofiltration pour séparer ensuite la solution en rétentat enrichi pour les cations polyvalents et perméat constitué par ladite solution purifiée, (iv) réaction sur les anions chlorure dans le perméat pour donner un composé contenant du chlore par électrolyse, et (v) recyclage d'au moins une partie du rétentat en étape de dissolution (i).
