Abstract

PROCEDIMIENTO PARA LA RECUPERACION DE ACIDO SULFURICO A PARTIR DE CORRIENTES RESIDUALES DE SULFURICO DE MEDIANA CONCENTRACION CONTAMINADAS CON MATERIA ORGANICA. EL PROCEDIMIENTO COMPRENDE LA REALIZACION DE LAS ETAPAS: (1) ELIMINACION PARCIAL DE LA MATERIA ORGANICA CONTENIDA EN LA CORRIENTE RESIDUAL DE SULFURICO, POR CALENTAMIENTO A 50-150C DE LA CORRIENTE RESIDUAL, SEGUIDO DE ENFRIAMIENTO A 20-60C Y FILTRACION; (2) CONCENTRACION DEL ACIDO POR TECNICAS CONVENCIONALES HASTA OBTENER UNA CORRIENTE CON ACIDO SULFURICO EN UNA CONCENTRACION DEL 70-85%; Y (3) OXIDACION COMPLETA DE LA MATERIA ORGANICA POR TRATAMIENTO CON H2O2 A UNA TEMPERATURA ENTRE 70 Y 160C. EL ACIDO SULFURICO ASI RECUPERADO ESTA PRACTICAMENTE EXENTO DE CONTAMINANTES ORGANICOS Y PUEDE LLEVARSE A LA CONCENTRACION DE CONSUMO POR DILUCION CON AGUA O POR RECONCENTRACION.
