Process for obtaining potassium chloride

A process for obtaining potassium chloride, comprising:

• a) submitting a brine to concentration;
• b) separating the brine after concentration resulting in a first solid content and a first liquid content;
• c) cooling the first liquid content;
• d) separating the first liquid content after cooling, thus resulting in a second solid content and a second liquid content;
• e) enriching the second solid content;
• and
• f) separating the second solid content after enrichment, thus resulting in a third solid content and a third liquid content, wherein submitting the brine to concentration is performed through thermal vapor recompression (TVR).

• wherein enriching the second solid content is carried out through a combination of operations of multistage evaporation and thermal vapor recompression (TVR), and operations of multistage evaporation and evaporation by mechanical vapor recompression (MVR).
