Process for regenerating a solution of monoethylene glycol containing water and dissolved salts, including the following steps: a) said solution is evaporated under vacuum in a first evaporation unit to produce a gaseous effluent including MEG and water, and a liquid residue enriched in MEG and in salts, a first portion of which is recycled into said first vacuum evaporation unit; b) a second portion of said liquid residue enriched in MEG and in salts is optionally sent into a tank in which the temperature of said second portion of said salt-enriched liquid residue is lowered so as to precipitate inorganic salts to form a stream enriched in precipitated salts, a first fraction of which is preferably recycled into the tank, and a stream depleted in precipitated salts recycled into the vacuum evaporation unit in step a); c) said second portion of said liquid residue enriched in MEG and in salts obtained from step a) or a second fraction of said stream enriched in precipitated salts obtained in step b) is sent, preferably intermittently, into a solid/liquid separation zone to separate a stream containing precipitated salts including inorganic salts and a liquid effluent including dissolved salts, among which are carboxylic acid salts; d) a portion or all of said liquid effluent obtained in step c) is sent, preferably intermittently, into a second evaporation unit different from the first vacuum evaporation unit to perform a separation between the MEG and, at least in part, the carboxylic acid salts by evaporating under vacuum the portion or all of said liquid effluent obtained in step c) to form a vapour enriched in MEG and depleted in carboxylic acid salts and a residual liquid effluent enriched in carboxylic acid salts; e) the vapour enriched in MEG and depleted in carboxylic acid salts is recycled into step a), or the vapour enriched in MEG and depleted in carboxylic acid salts is mixed with the gaseous effluent including MEG and water obtained from step a), and said gaseous effluent including MEG and water obtained from step a) or said mixture is used to produce the regenerated MEG solution. a) said solution is evaporated under vacuum in a first evaporation unit to produce a gaseous effluent including MEG and water, and a liquid residue enriched in MEG and in salts, a first portion of which is recycled into said first vacuum evaporation unit; b) a second portion of said liquid residue enriched in MEG and in salts is optionally sent into a tank in which the temperature of said second portion of said salt-enriched liquid residue is lowered so as to precipitate inorganic salts to form a stream enriched in precipitated salts, a first fraction of which is preferably recycled into the tank, and a stream depleted in precipitated salts recycled into the vacuum evaporation unit in step a); c) said second portion of said liquid residue enriched in MEG and in salts obtained from step a) or a second fraction of said stream enriched in precipitated salts obtained in step b) is sent, preferably intermittently, into a solid/liquid separation zone to separate a stream containing precipitated salts including inorganic salts and a liquid effluent including dissolved salts, among which are carboxylic acid salts; d) a portion or all of said liquid effluent obtained in step c) is sent, preferably intermittently, into a second evaporation unit different from the first vacuum evaporation unit to perform a separation between the MEG and, at least in part, the carboxylic acid salts by evaporating under vacuum the portion or all of said liquid effluent obtained in step c) to form a vapour enriched in MEG and depleted in carboxylic acid salts and a residual liquid effluent enriched in carboxylic acid salts; e) the vapour enriched in MEG and depleted in carboxylic acid salts is recycled into step a), or the vapour enriched in MEG and depleted in carboxylic acid salts is mixed with the gaseous effluent including MEG and water obtained from step a), and said gaseous effluent including MEG and water obtained from step a) or said mixture is used to produce the regenerated MEG solution.
