Abstract

INHIBIDOR DE LA CORROSION PARA SISTEMAS DE TRATAMIENTO DE GASES DE ALCANOLAMINAS. ESTA FORMADO DICHO INHIBIDOR POR UN COMPUESTO DE VANADIO EN CONDICIONES QUE EL VANADIO SE ENCUENTRE EN EL ESTADO DE VALENCIA +4 O +5 Y POR UN COMPUESTO ORGANICO ELEGIDO DEL GRUPO QUE CONSISTE EN ACIDOS AROMATICOS NITRO-SUSTITUIDOS, SALES DE ACIDOS NITRO-SUSTITUIDOS, 1,4-NAFTOQUINONA Y MEZCLAS DE LOS MISMOS. ESTE INHIBIDOR SE DEBE HACER INTERACCIONAR CON EL AZUFRE QUE ESTE PRESENTE EN LA SOLUCION DE ALCANOLAMINAS, UTILIZANDOSE EL COMPUESTO DE VANADIO Y EL COMPUESTO ORGANICO EN CANTIDADES INFERIORES A SUS CONCENTRACIONES EFICACES MINIMAS INDIVIDUALES.
