Abstract
METODO PARA PREVENIR LA CORROSION EN UN SISTEMA ACUOSO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE ANALIZA EL AGUA PARA DETECTAR LA PRESENCIA DE ACCION CORROSIVA; SEGUNDA, SE AÑADEN AL AGUA, ANTES O DESPUES DE LA ENTRADA EN EL SISTEMA, CANTIDADES CONTROLADAS DE ACIDO 5-AMINO-1,2,4-TRIAZOL-3-CARBOXILICO O DE UNA SAL DEL MISMO; Y POR ULTIMO, SE SEPARA CONTINUAMENTE PARTE DEL AGUA DESDE EL SISTEMA Y SE AÑADE A ESTE UNA CANTIDAD CORRESPONDIENTE DE AGUA DE NUEVA APORTACION. EL TRIAZOL SE AÑADE AL SISTEMA HASTA OBTENER UNA CONCENTRACION COMPRENDIDA ENTRE 0,5 Y 20 MILIGRAMOS POR LITRO.
