Abstract
La presente invención se refiere a un procedimiento para preparar, bajo condiciones de reducción, licores de cocimiento que tienen una alta sulfidez para cocimiento de pulpa de sulfato, donde el licor negro formado en el procedimiento de cocimiento se alimenta, despues de la evaporación, completamente o parcialamente, a un reactor que opera a una temperatura creciente la cual es obtenida medianta el suministro de energía desde una fuente de calor externa y/o la liberación de energía desde el licor negro, una fundición que consisite esencialmente en sulfuro de sodio que se forma y se retira para ser adicionalmente procesado en licor de cocimiento, caracterizado porque en adición, se alimentan al reactor todos o parte de los materiales que contienen azufre y/o que contienen azufre y sodio, presentes en el molino de pulpa, incluyendo los ingredientes químicos de formación que contienen azufre y/o que contienen sodio y azufre utilizados para el balance de ingrediente químicos totales del molino de pulpa, de tal maneta que la proporción molar del sodio al azufre en la mezcla total alimentada al reactor está dentro del margen de 1.5 a 4.
