Abstract

a. L'invention concerne un procédé de fabrication de chlore et de carbonate de sodium monohydraté. b. On électrolyse une solution aqueuse de chlorure de sodium dans une cellule à membrane à perméabilité sélective, on carbonate le catholyte in situ dans la cellule, on évapore la solution carbonatée résultante pour séparer du carbonate de sodium monohydraté et une eau mère, on bicarbonate l'eau mère et on la recycle dans la chambre cathodique de la cellule. c. L'invention s'applique notamment à la production de carbonate de sodium anhydre dense, à partir de carbonate de sodium monohydraté.at. The invention relates to a method of making chlorine and sodium carbonate monohydrate. b. An aqueous solution of sodium chloride is electrolyzed in a selective permeability membrane cell, the catholyte is carbonated in situ in the cell, the resulting carbonate solution is evaporated to separate sodium carbonate monohydrate and mother liquor, the water is bicarbonate. mother water and it is recycled in the cathode chamber of the cell. vs. The invention applies in particular to the production of dense anhydrous sodium carbonate, from sodium carbonate monohydrate.
