Abstract (en)
[origin: WO2019234665A1] In the context of the technology for producing caustic potash (in solution or as a solid phase) from potassium chloride, by an electrolytic process with membrane cells, the present invention is aimed at a process of dechloratation of KC1 brine, in particular half-saturated KC1 brine, which enables a KOH-based end product to be obtained on an industrial scale, such as, for example, 30% w/w or 50% w/w KOH in aqueous solution (potash), or solid KOH, containing the smallest possible amount of chlorate ions, in particular, less than 30 ppm; substantially devoid of chlorates, or completely devoid of chlorates.
