Abstract

Un procedimiento para la recuperación de productos químicos a partir de agua salina, que comprende: convertir los sulfatos contenidos en el agua salina en sulfato de sodio, y separar esencialmente la totalidad del calcio y el magnesio del agua salina para formar una primera solución agotada en magnesio y en calcio, mezclar la primera solución con cloruro de sodio re-circulado para formar una segunda solución reforzada en cloruro de sodio, obtener por cristalización y separar después cristales de cloruro de sodio a partir de la segunda solución para formar una tercera solución separar bromo de la tercera solución para formar una cuarta solución, obtener por cristalización cristales de cloruro de sodio y sulfato de sodio a partir de la cuarta solución, obtener por cristalización cristales de cloruro de sodio y sulfato de sodio a partir de la cuarta solución para formar una quinta solución separar los cristales de cloruro de sodio y sulfato de sodio unos de otros y de la quinta solución para formar una sexta solución mezclar los cristales de cloruro de sodio separados de la quinta solución con la primera solución, separar sulfatos residuales de la sexta solución para formar una séptima solución obtener por cristalización y separar después cristales de cloruro de sodio de la séptima solución para formar una octava solución mezclar los cristales de cloruro de sodio separados de la séptima solución con la primera solución y obtener por cristalización y separar después cristales de cloruro de potasio de la octava solución.
