Abstract

PROCEDIMIENTO DE ABSORCION DE GASES NITROSOS. CONSISTE EN HACER CIRCULAR LA MEZCLA GASEOSA QUE CONTIENE NO Y O2 A TRAVES DE UN TUBO DE CIRCULACION, FORMANDOSE NO2, CONDUCIENDOSE A CONTINUACION LA MEZCLA GASEOSA DESDE ABAJO A TRAVES DE TUBO DE VACIO A UNA VELOCIDAD COMPRENDIDA ENTRE 10 Y 30 CM./SG., A TRAVES DE UNA COLUMNA DE BURBUJAS RELLENA CON AGENTE ACUOSO DE ABSORCION QUE SE DIVIDE EN VARIAS ZONAS COLOCADAS UNAS SOBRE OTRAS Y SE DESCOMPONEN LAS GRANDES BURBUJAS DE GAS QUE APARECEN AL SUBIR EN EL AGENTE ACUOSO DE ABSORCION EN BURBUJAS MAS PEQUEÑAS POR MEDIO DE LOS ORGANOS DE DISTRIBUCION INCORPORADOS. EL TRATAMIENTO SE EFECTUA EN UN REACTOR TUBULAR Y EN UNA COLUMNA DE BURBUJAS EN 2 HASTA 10 REACTORES TUBULARES Y COLUMNAS DE BURBUJAS DISPUESTOS ALTERNATIVAMENTE UNOS TRAS OTROS. COMO AGENTE ACUOSO DE ABSORCION SE UTILIZA ACIDO NITRICO DILUIDO, CUYO PH ES 7, POR LO MENOS. I
