Abstract

Un método de apagado de la cal viva para formar partículas finas de hidróxido de calcio, comprendiendo el método las etapas de: - proporcionar una fuente de cal viva y una fuente de agua de apagado; - poner en contacto la cal viva con el agua de apagado para formar producto de hidróxido de calcio; caracterizado por que la fuente provista de cal viva es una cal viva con alto contenido en sulfato formada a partir de la calcinación de piedra caliza utilizando una fuente de combustible sólido, a excepción del gas natural, en un calcinador, y por que dicho método comprende además las etapas de mezclar un agente complejante con la cal viva de alto contenido en sulfato o con el agua de agotado, inmovilizando los iones sulfato solubles disponibles presentes en la cal viva después de la adición de la cal viva al agua de apagado mediante dicho agente complejante; controlando de este modo la presencia de iones sulfato solubles durante la operación de apagado y evitando la aglomeración indeseable de partículas de hidróxido de calcio.
