Abstract

ESTA INVENCION SUMINISTRA UN METODO PARA EL PERFECIONAMIENTO EN LA PREPARACION DE PULPA CELULOSICA DE MADERA PARA SU UTILIZACION EN LA FABRICACION DE PAPEL Y ESPECIALMENTE PARA EL MEJORAMIENTO DE LA CALIDAD DE LA PULPA QUE HA SIDO SOMETIDA A AGENTES BLANQUEANTES BASADOS EN CLORO, MEDIANTE EL SOMETIMIENTO DE LA PULPA A LA ACCION DEL OZONO ANTES DE LA FASE DE EXTRACCION EN LA SECUENCIA DE BLANQUEADO. LA PULPA MEJORADA POR MEDIO DE ESTA INVENCION INCLUYE LA REDUCCION DE TODOS LOS RESIDUOS CLORADOS ORGANICAMENTE ENLAZADOS EN LA PULPA DE MADERA Y LOS HALADOS ORGANICOS ADSORBIDOS (AOX) EN EL EFLUENTE, Y LA PULPA CONSERVANDO UN BUEN BRILLO Y VISCOSIDAD. LAS VENTAJAS DE ESTA INVENCION HAN SIDO REALIZADAS POR MEDIO DE UNA SECUENCIA DE BLANQUEADO QUE EMPLEA SOLAMENTE CUATRO FASES, LLAMADAS DZED O D SUB C ZED, Y QUE REQUIEREN UNA INVERSION DE CAPITAL RELATIVAMENTE MODESTO, LO CUAL LAS HACEN COMERCIALES.
