Abstract
LOS LIQUIDOS DE LAVADO ACIDO, QUE SON UTILIZADOS EN ZONAS DE LAVADO CON UN VALOR DE PH MENOR DE 3, SIRVEN PARA LA ELIMINACION DE LOS COMPUESTOS ACIDOS DE UN GAS. EL LIQUIDO DE LAVADO ES CONDUCIDO AL MENOS PARCIALMENTE EN UN CICLO. SE MEZCLA UNA CORRIENTE PARCIAL CONSTANTE DEL LIQUIDO DE LAVADO CON UNA CORRIENTE DE SOSA DE CONCENTRACION CONSTANTE Y VOLUMEN CONSTANTE POR UNIDAD DE TIEMPO, SE MIDE DE FORMA USUAL EL VALOR PH DE LA MEZCLA, SE AJUSTA EL VALOR TEORICO DEL VALOR DEL PH DE LA MEZCLA SOBRE UN VALOR EN LA ZONA DE 5 HASTA 9 Y SE AÑADE UN LIQUIDO DE CORRECCION ALCALINO O NEUTRO DE UN VALOR DE PH MEDIDO AL LIQUIDO DE LAVADO. EL LIQUIDO DE LAVADO PUEDE ESTAR COMPUESTO PRINCIPALMENTE DE AGUA.
