Abstract

ESTE INVENTO MUESTRA EL PROCESO DE BLANQUEADO DE PULPA QUIMICA, PROCESO QUE COMPRENDE UNA O VARIAS FASES DE OXIDACION Y UNA O VARIAS FASES DE TRATAMIENTO ALCALI EN EL QUE LA PULPA ES TRATADA CON UN ENZIMA. LA IDEA BASICA DEL INVENTO ES QUE LA PULPA ES TRATADA CON UN ENZIMA EN DOS O MAS FASES DIFERENTES DEL PROCESO Y PREFERIBLEMENTE SE LLEVA A CABO UN TRATAMIENTO ALCALI Y/O OXIDACION ENTRE LAS FASES DEL TRATAMIENTO DE ENZIMA. EL ELEMENTO QUIMICO OXIDANTE UTILIZADO ES PREFERENTEMENTE EL OXIGENO, AUNQUE PUEDEN USARSE ADEMAS O EN SU SUSTITUCION PEROXIDO Y/O CLORO Y/O DIOXIDO DE CLORO, Y EN LAS FASES DEL TRATAMIENTO DE ENZIMA, PREFERENTEMENTE ENTRE 2 Y 4, SE PUEDE UTILIZAR LA MISMA ENZIMA O ALTERNATIVAMENTE DOS O MAS ENZIMAS DIFERENTES. MEDIANTE EL TRATAMIENTO DE ENZIMA DEL INVENTO, LA CANTIDAD DE COMPUESTOS ORGANICOS TOXICOS EN EL BLANQUEADO DISMINUYE Y AL MISMO TIEMPO EL CONSUMO DE OXIGENO QUIMICO DEL EFLUENTE ES MENOR.
