Abstract

PROCEDIMIENTO PARA LA VALORACION DE LOS LODOS DE CAL EN EL CICLO DE CAUSTIFICACION PARA LA PREPARACION DE LAS PASTAS KRAFT. COMPRENDE: A) DILUIR AL SALINO CON UN LICOR BLANCO FLOJO, PARA PRODUCIR LICOR VERDE; B) CENTRIFUGAR AL LICOR VERDE A 80JC, PARA FILTRARLO Y EVITAR PERDIDAS TERMICAS; C) AGITAR AL FILTRADO A 100JC, PARA SEPARAR CAL VIVA DEL LICOR VERDE FILTRADO Y REALIZAR UNA LECHADA DE CAL APAGADA; D) ELIMINAR LOS INCOCIDOS DEL LICOR VERDE FILTRADO DE C); E) CAUSTIFICAR AL LICOR VERDE FILTRADO DE A) CON CARBONATO SODICO, PARA OBTENER UN LICOR BLANCO CON CO3CA; F) GRANULOMETRAR AL CO3CA EN EL LICOR BLANCO HASTA UN TAMAÑO DE 40 M; G) FILTRAR AL LICOR BLANCO PARA SEPARAR AL CO3CA; H)LAVAR AL PRECIPITADO DE CO3CA CON H2O A 80JC; I) CONCENTRAR A SEQUEDAD AL LAVADO DE H); J) TRITURAR AL CONCENTRADO DE CO3CA CON UN DISPERSANTE ENTRE UN 72 A 74%, EN UN TRITURADOR DE BOLAS DE ZR; Y K) BLANQUEAR AL TRITURADO DE J) CON AGENTES OXIDANTES. EL SALINO UNA DISOLUCION DE SULFURO SODICO Y CARBONATO SODICO EN AGUA, EL LICOR BLANCO FLOJO UNA DISOLUCION DE SOSA Y SULFURO SODICO EN AGUA, EL AGENTE DISPERSANTE ES POLIFOSFATO SODICO Y EL AGENTE OXIDANTE ES H2O2.
