Abstract

LOS COMPUESTOS AROMATICOS EN PEQUEÑAS CANTIDADES ACTUAN COMO ADITIVOS ANTIINCRUSTANTES EN LOS HORNOS PARA PIROLISIS QUE ESTAN SOMETIDOS A TEMPERATURAS ELEVADAS, DESDE APROXIMADAMENTE 500 LOS HIDROCARBUROS EN ETILENO ASI COMO EN OTROS PRODUCTOS UTILES. ESTOS HORNOS PRODUCEN MATERIAL QUE SE DEPOSITA Y ACUMULA SOBRE LAS SUPERFICIES DEL HORNO, ENTRE LAS QUE SE INCLUYEN LOS SERPENTINES RADIANTES DEL HORNO Y LOS INTERCAMBIADORES DEL CIRCUITO DE TRANSFERENCIA. LOS PRESENTES ADITIVOS ANTIINCRUSTANTES INHIBEN Y SUPRIMEN LA FORMACION Y DEPOSICION DE MATERIAL SOBRE LAS SUPERFICIES DEL HORNO. LA PRESENTE INVENCION CONSISTE EN UN METODO PARA INHIBIR LA FORMACION DE COQUE SOBRE LAS SUPERFICIES DE UNA SECCION DE CALEFACCION POR CALOR RADIANTE DE UN HORNO PARA PIROLISIS Y LAS SUPERFICIES SITUADAS INMEDIATAMENTE A CONTINUACION DE ESA SECCION EN CONTACTO CON UNA CARGA DE HIDROCARBUROS QUE COMPRENDE EL RASCADO DEL HORNO PARA PIROLISIS Y, ANTES DE PROCESAR LA CARGA DE HIDROCARBUROS, LA ADICION DE UN COMPUESTOINHIBIDOR AL HORNO PARA PIROLISIS. EL COMPUESTO INHIBIDOR SE ELIGE ENTRE UN GRUPO DE COMPUESTOS QUE INCLUYE BENCENOS SUSTITUIDOS, NAFTALENOS SUSTITUIDOS, ANTRACENOS SUSTITUIDOS, FENANTRENOS SUSTITUIDOS Y MEZCLAS DE LOS MISMOS DONDE EL COMPUESTO INHIBIDOR CONTIENE AL MENOS UN SUSTITUYENTE QUE TIENE AL MENOS 2 ATOMOS DE CARBONO. SOBRE LAS SUPERFICIES DEL HORNO PARA PIROLISIS, SE FORMA UNA FINA CAPA DE COQUE SIN ACTIVIDAD CATALITICA. A CONTINUACION, SE ALIMENTA EL HORNO CON LA CARGA DE HIDROCARBUROS, DE MANERA QUE LAS SUPERFICIES DEL HORNO QUEDAN PROTEGIDAS DE LA FORMACION DE COQUE CON ACTIVIDAD CATALITICA DURANTE EL PROCESAMIENTO DE LA CARGA DE HIDROCARBUROS.
