Abstract

Den foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av en klorholdig forbindelse ved bruk av en vandig saltoppløsning inneholdende minst 100 g/l natriumklorid og en forurensende mengde av polyvalente kationer, omfattende trinnene (i) fremstilling av en vandig saltoppløsning inneholdende minst 100 g/l natriumklorid og minst 0,01 ppm polyvalente kationer ved å oppløse en natriumkloridkilde i vann, (ii) tilsetning av en effektiv mengde av minst én positiv retensjonsforbedrende komponent til den vandige oppløsning, (iii) deretter underkastes oppløsningen et nanofiltreirngstrinn slik at oppløsningen separeres i et retentat som er anriket på polyvalente kationer og et permeat som er den rensede vandige saltoppløsning, (iv) kloridanionene i permeatet omsettes til en klorholdig forbindelse ved hjelp av et elektrolysetrinn, og (v) i det minste en del av retentatet resirkuleres til et oppløsningstrinn (i).The present invention relates to a method for producing a chlorine-containing compound using an aqueous salt solution containing at least 100 g/l sodium chloride and a contaminating amount of polyvalent cations, comprising the steps (i) producing an aqueous salt solution containing at least 100 g/l sodium chloride and at least 0.01 ppm 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) then subjecting the solution to a nanofiltration step so that the solution is separated into a retentate which is enriched in polyvalent cations and a permeate which is the purified aqueous salt solution, (iv) the chloride anions in the permeate are converted to a chlorine-containing compound by means of an electrolysis step, and (v) at least part of the retentate is recycled to a dissolution step (i ).
