Abstract

SE PRESENTA UN METODO Y UN EQUIPO PARA BLANQUEAR PULPA LIGNOCELULOSA CON OZONO, MIENTRAS SE RECUPERA UN GAS RICO EN OXIGENO QUE PUEDE RECICLARSE O REUTILIZARSE. EL BLANQUEADO DE LA PULPA CON OZONO SE LLEVA A CABO PREFERIBLEMENTE BAJO CONDICIONES EN LAS CUALES SE EVITA EL INGRESO DE AIRE. EN UN PROCESO DE BLANQUEADO MULTIETAPA, PUEDE RECUPERARSE UN GAS RICO EN OXIGENO QUE CONTENGA TIPICAMENTE AL MENOS UN 90% DE SU PESO DE OXIGENO A PARTIR DEL SEGUNDO CONTACTOR PARA SU USO POTENCIAL EN DIFERENTES OPERACIONES QUE CONSUMAN OXIGENO EN UN MOLINO DE PULPA.
