Abstract

REIVINDICACION NUMERO UN METODO PARA CONTROLAR EL PROCESO DE BLANQUEA- MIENTO CON OZONO, HASTA UN GRADO DESEADO DE BLAN- QUEAMIENTO, QUE COMPRENDE: (a) AGREGAR ALIMENTACION DE OZONO A UNA CANTIDAD DESEADA DE LA PASTA; (b) PASAR LA PASTA DENTRO Y FUERA DE UN REACTOR DE BLANQUEAMIENTO; Y (c) AJUSTAR LA CANTIDAD DE ALIMENTACION DE OZONO EN RESPUESTA A UNA PROPIEDAD MEDIDA DE LA PASTA, HASTA EL VALOR NECESARIO PARA OBTENER UN GRADO DE- SEADO DE BLANQUEAMIENTO". FIGURA 1CLAIMED NUMBER A METHOD TO CONTROL THE OZONE BLEACHING PROCESS, TO A DESIRED DEGREE OF WHITENING, WHICH INCLUDES: (a) ADDING OZONE FEEDING TO A DESIRED AMOUNT OF PASTA; (b) PASSING THE PASTA INSIDE AND OUT OF A WHITENING REACTOR; AND (c) ADJUST THE FEED AMOUNT OF OZONE IN RESPONSE TO A MEASURED PROPERTY OF THE PASTA, UP TO THE NECESSARY VALUE TO OBTAIN A DESIRED DEGREE OF WHITENING.
