Summary:Device and process for desalting brines from saline desalination plants with a solvent miscible with water, which comprises adding to a brine feed the amount of at least one solvent c 1 -c 5 miscible with the water necessary to form a brine-solvent mixture in the range of 9: 1 to 1: 4; separating the precipitated salts obtaining a stream of brine with a reduced salt content; distilling said stream, recovering the solvent that can be returned to the solvent tank or burned to produce heat and/or electricity and obtaining a second stream of brine with a reduced salt content, which is subjected to reverse osmosis and then to a new one distillation stage, obtaining a deposit of precipitated salts and a stream of pure water.
