Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE LIMPIEZA, EN PARTICULAR PARA UN COMPONENTE, QUE ES ESPECIALMENTE UN GENERADOR DE VAPOR. PARA ELLO SE UTILIZA UN FORMADOR COMPLEJO. SE HA PREVISTO QUE PARA LA ELIMINACION DEL PLOMO METALICO DE ESTE COMPUESTO OXIDADO Y CON ELLO GENERADO, MIENTRAS AUN EL PLOMO ES OXIDADO, SE SOMETE A UN PROCESO DE COMPLEJIDAD. PARA ELLO SE UTILIZA COMO FORMADOR COMPLEJO UNA SAL A PARTIR DE UN OXIDO FORMADOR COMPLEJO Y UN AGENTE DE ALCANILIZACION EN SOLUCION ACUOSA. EL VALOR DE PH DE ESTA SOLUCION PUEDEN ENCONTRARSE ENTRE 8 Y 11. DESPUES DE LA FORMACION DE UN COMPLEJO DE PLOMO SE ELIMINA LA SOLUCION QUE APARECE.
