INDUSTRIAL CHEMI-MECHANICAL PULPS BLEACHING: ONE STAGE AND TWO STAGE COMPARISON
The objective of this work is to compare a one-stage and a two-stage processes performance, in hydrogen peroxide bleaching of a hardwood chemi-mechanical pulp. Cold soda pulps from Celulosa Argentina S.A. Zárate mill were used as raw material (eucalyptuspoplar mixtures). Preliminary tests were made...

| description | The objective of this work is to compare a one-stage and a two-stage processes performance, in hydrogen peroxide bleaching of a hardwood chemi-mechanical pulp. Cold soda pulps from Celulosa Argentina S.A. Zárate mill were used as raw material (eucalyptuspoplar mixtures). Preliminary tests were made to observe the pulp behavior using a oneor a two-stage bleaching process as a function of the reaction time. Based on laboratory results, a two stage bleaching process is considered the best option. Alternatives of process modification are proposed supported by the present mill technology. |

El objetivo del trabajo es comparar el blanqueo con peróxido de hidrógeno de pulpas quimimecánicas de latifoliadas implantadas, utilizando procesos en una y dos etapas. Se emplearon pulpas a la soda fría de mezclas salicáceas y eucalyptus provenientes de la fábrica Zárate de Celulosa Argentina S.A. Se realizaron ensayos preliminares con el objetivo de observar el comportamiento de la pulpa al aplicar un blanqueo en una y dos etapas, con respecto al tiempo de reacción. Sobre la base de los resultados de laboratorio, se considera superior la aplicación de un sistema de blanqueo en dos etapas. Se proponen alternativas de modificación del proceso aprovechando la tecnología disponible en la fábrica.
