Abstract

Un método de eliminar sulfuros y otros contaminantes volátiles de un condensado de vapores de lejías procedente de un procedimiento de fabricación de pasta papelera, en el que dicho condensado de vapores de lejías se introduce en una columna de lavado (1) que forma parte de un circuito cerrado que se compone de dicha columna de lavado (1), una unidad de oxidación térmica regenerativa (RTO) (2) y un absorbedor de SO2, en cuyo circuito se hace circular un gas (4), que consta principalmente de aire y los componentes formados o extraídos en el circuito y en el que el gas que circula extrae los sulfuros y otros compuestos volátiles del condensado (5) de vapores de lejías, después de lo cual la corriente gaseosa (6) se introduce en la unidad de la planta (OTR) (2), en donde los compuestos extraídos se queman formando SO2, y después el gas (7) enriquecido en SO2 se envía al absorbedor de SO2 (3)en donde se utiliza preferiblemente un álcali como medio de absorción (8), después de lo cual el gas quecircula en la planta se devuelve a la columna de lavado (1).
