摘要: Processes are described which include: (a) providing an initial crude alkali metal chloride brine; (b) mixing the initial crude brine with a recirculated brine to form a process brine steam; (c) subjecting the process brine stream to electrolysis to form chlorine gas and an electrolyzed weak brine; and (d) subjecting the electrolyzed weak brine to a post-electrolysis salt enrichment comprising (i) diverting a substream of the electrolyzed weak brine at a post-electrolysis diversion point; (ii) removing water from the substream; (iii) crystallizing salt present in the substream; (iv) separating the crystallized salt from the substream; and (v) introducing the separated salt into the electrolyzed weak brine to form the recirculated brine.
