Title (EN) METHOD OF CONCENTRATING ALKALI METAL HYDROXIDE IN A CASCADE OF HYBRID CELLS
(FR) PROCEDE DE CONCENTRATION D"UN HYDROXYDE DE METAL ALCALIN DANS UNE CASCADE DE CELLULES HYBRIDES
Abstract: front page image
(EN)Process for the simultaneous production of alkali metal hydroxide and electrical energy. A plurality of hybrid cells (1) are operated in series with an aqueous solution of alkali metal hydroxide introduced as anolyte into an anode compartment of a first hybrid cell (6) at one end of the series and an aqueous fluid medium receptive to alkali metal ions introduced as catholyte into a cathode of a last hybrid cell (7) at an opposite end of the series of cells (1). The anolyte is caused to flow through the anode compartments (3) of the cells (1) in sequence from the first cell (6) to the last cell (7) of the series of cells (1). The catholyte is caused to flow through the cathode compartments (4) in sequence from the last cell (7) to the first cell (6) countercurrently to the flow of anolyte from hybrid cell to hybrid cell of the series of cells (1).
(FR)Procede de production simultanee d"un hydroxyde de metal alcalin et d"energie electrique. Une pluralite de cellules hybrides (1) fonctionne en serie avec une solution aqueuse d"un hydroxyde de metal alcalin introduit comme anolyte dans un compartiment d"anodes d"une premiere cellule hybride (6) a une extremite de la serie et un milieu de fluide aqueux receptif aux ions de metal alcalin introduit comme catholyte dans une cathode d"une derniere cellule hybride (7) a une extremite opposee de la serie de cellules (1). L"anolyte s"ecoule sequentiellement au travers des compartiments d"anodes (3) des cellules (1) a partir de la premiere cellule (6) jusqu"a la derniere cellule (7) de la serie de cellules (1). Le catholyte s"ecoule sequentiellement au travers des compartiments de cathode (4) a partir de la derniere cellule (7) jusqu"a la premiere cellule (6) a contre-courant par rapport a l"ecoulement de l"anolyte d"une cellule hybride a une autre cellule hybride de la serie de cellules (1).
