Abstract

SEGUN EL METODO PROPUESTO DE LAVADO (3) DE GASES DE COMBUSTION CON UNA SOLUCION CONTENIENDO UN ALCALI Y SIENDO LIMPIADOS ANTES O DESPUES DE UNA ETAPA (4) DE OXIDACION, SE DISPONE DE UNA OPERACION (6) QUE COMPRENDE UNA COMBINACION DE SEDIMENTACION Y FILTRACION DE MEMBRANA. AL MENOS UNA PARTE DE LOS SOLIDOS SE SEPARAN EN EL CONCENTRADO OBTENIDO A PARTIR DE LA FILTRACION DE MEMBRANA MEDIANTE SEDIMENTACION Y EL LIQUIDO QUE PERMANECE SE REALIMENTA AL PROCESO DE FILTRACION DE MEMBRANA Y DE AQUI AL CIRCUITO PRINCIPAL, ELIMINANDOSE EL SULFATO DE METAL ALCALINO CRISTALIZADO. SE OBTIENE DE ESTA FORMA UN SULFATO DE METAL ALCALINO BLANCO PURO LIBRE DE IMPUREZAS DE COLORACION OSCURA DE FORMA ADECUADA DE COSTE.
