Abstract

PROCEDIMIENTO PARA CONCENTRAR SO2 DE CORRIENTES DE GASES. LA CORRIENTE DE GASES SE HACE PASAR POR UNA SOLUCION ABSORBENTE ACUOSA DE UNA SAL BASICA DE ALUMINIO QUE PRESENTA UNA CONCENTRACION EN A13+ ENTRE 5 Y 50 G/1. ESTA SOLUCION DE ABSORCION SE ENCUENTRA EN UN CIRCUITO QUE PASA EN PRIMER LUGAR POR UNA ZONA DE ABSORCION Y DESPUES POR UNA DESABSORCION QUE SE MANTIENE A UNA PRESION ABSOLUTA ENTRE 0,08 Y 0,7 BARES. EN LA ZONA DE DESABSORCION SE DESPRENDE UNA CORRIENTE DE VAPOR ENRIQUECIDO CON SO2 POR AUMENTO DE LA SUPERFICIE DEL LIQUIDO.
