Abstract
Un proceso para la reducción del contenido orgánico de una salmuera agotada proveniente de la producción de compuestos epoxi que incluye un paso de destilación por arrastre con vapor y una mineralización con hipoclorito en dos pasos, en determinadas condiciones de pH y temperatura. Reivindicación 1: Un proceso para la reducción del contenido orgánico de una corriente residual que consiste en una salmuera agotada, en una planta de síntesis de un compuesto epoxi por oxidación de un material orgánico en bruto por medio de los productos de una unidad de electrólisis de cloro-álcali alimentada con salmuera fresca, caracterizado porque comprende los siguientes pasos en secuencia: a) inyectar un flujo de agua en la salmuera agotada que se desea tratar y destilar por arrastre con vapor; b) realizar una preoxidación con hipoclorito a un pH de entre 3,5 y 5 y a una temperatura de entre 50 y 60ºC; c) realizar la oxidación final en presencia de hipoclorito a un pH entre 3 y 4 y a una temperatura de entre 80 y 95ºC para obtener una salmuera fresca.
