METHOD FOR REGENERATING AN AQUEOUS SOLUTION OF MEG CONTAINING SALTS WITH PURGE TREATMENT

The present invention relates to a process for regenerating a rich MEG aqueous solution (100), recovering a maximum amount of MEG while at the same time removing the carboxylic acid salts, including:a) vacuum evaporation of the solution (100) in a unit (1000);b) optional precipitation in a tank (1002) of the inorganic salts of a portion (105) of the liquid residue enriched in MEG and in salts (104) obtained from a);c) removal of the precipitated inorganic salts in a solid/liquid separation unit (1003);d) sending all or part (114) of the liquid effluent (112) obtained from c) into a separation unit (1004) different from the unit (1000) to form, notably, an MEG stream depleted in carboxylic acid salts or in carboxylic acids (115);e) recycling of said stream (115) into step a).
