Abstract
Un método de procesamiento de pulpa incluye una etapa de extracción cáustica en frío en la cual la solución cáustica en frío utilizada y el líquido utilizado para lavar la pulpa extraída son concentrados por un sistema de evaporación . El líquido concentrado puede utilizarse como parte del licor de neutralización y cocción en el proceso de pulpa, conduciendo a una mayor eficiencia sin reducir significativamente la calidad de la pulpa . El filtrado altamente concentrado de la etapa de extracción cáustica en frío puede ayudar a reducir el depósito de hemicelulosa madera durante el paso de cocción .
