Abstract

LA PRESENTE INVENCION SE REFIERE A UNA OXIDACION PARCIAL, PROCESO DE GASIFICACION QUE USA UN ALIMENTADOR DE HIDROCARBURO DE BAJO GRADO QUE ENVUELVE LOS PASOS DE GASIFICACION, RECUPERACION DEL CALOR RESIDUAL Y ELIMINACION DEL CARBON BAJO LA FORMACION DE UN COMPUESTO ACUOSO DE HOLLIN QUE CONTIENE CARBON INCOMBUSTO Y CENIZA. EL COMPUESTO ACUOSO DE HOLLIN SE FILTRA PARA FORMAR UNA TORTA DE FILTRO DE CARBON Y CENIZA, CUYA TORTA SE ELIMINA DEL PROCESO. DE ESTE MODO SE ESTABLECE UN PROCESO DE OXIDACION PARCIAL DE PROCESO DIRECTO QUE EVITA EL RECICLADO DEL CARBON INCOMBUSTO Y LA CENIZA. EL METODO TAMBIEN COMPRENDE LA FILTRACION DE COMPUESTOS ACUOSOS DE HOLLINCENIZA QUE CONTIENEN DE UN 0,5 A UN 3 % DE CARBON INCOMBUSTO Y DE UN 0,1 A UN 2% DE CENIZA QUE TIENE CANTIDADES APRECIABLES DE FE, NI Y V. EL COMPUESTO ACUOSO SE ENFRIA HASTA UNA TEMPERATURA INFERIOR A 80 C Y SE FILTRA MIENTRAS SE CONFINA ENTRE CORREAS CERRADAS MOVIBLES QUE MANTIENEN UNA PRESION CONSTANTE CONTRA LA DISMINUCION DE VOLUMEN DE LAMASA DE PARTICULAS DE CARBON/CENIZAS HASTA QUE SE REDUCE EL CONTENIDO DE HUMEDAD POR DEBAJO DEL 80% EN PESO. SE AÑADEN AGENTES FLOCULANTES AL COMPUESTO ACUOSO DE HOLLIN ANTES DE LA FILTRACION, UNO EN FORMA DE AGENTE DE FLOCULACION CATIONICO Y EL OTRO EN FORMA DE AGENTE DE FLOCULACION ANIONICO. SE OBTIENE UNA TORTA DE FILTRO DESMENUZABLE O GRANULAR ADECUADA PARA UN PROCESAMIENTO ADICIONAL.
