Abstract

METODO PARA INHIBIR LA FORMACION DE DEPOSITOS DE INCRUSTACIONES EN LAS SUPERFICIES DE UN DEPURADOR ALCALINO UTILIZADO PARA LAVAR GASES ACIDOS GENERADOS DURANTE LA FABRICACION DE OLEFINAS; DICHOS DEPOSITOS SE FORMAN DURANTE LA DEPURACION DE HIDROCARBUROS PRODUCIDOS PIROLITICAMENTE CONTAMINADOS CON COMPUESTOS QUE CONTIENEN OXIGENO CON UNA SOLUCION CAUSTICA DE PH > 7. EL METODO CONSISTE EN AÑADIR UNA CANTIDAD EFICAZ INHIBIDORA DE LA DEPOSICION DE UNA AMINA AROMATICA SUSTITUIDA SOLUBLE EN SOLUCION CAUSTICA SELECCIONADA DEL GRUPO FORMADO POR: 2 NOL, 4 AMINOFENOL, ACIDO 4 MISMO, 4 BENZOICO Y SALES DEL MISMO, ACIDO 3 ON CAUSTICA. COMO AMINA AROMATICA SUSTITUIDA SE PREFIERE LA SAL SODICA DEL ACIDO 4
