Abstract

En un procedimiento para la preparacion de metal fundido se hace ingresar oxígeno, agentes de reduccion y hierro reducido en un reactor de reduccion (1), a un gasificador de fusion (3). El agente de reduccion se gasifica con el oxígeno y a través del calor producido durante el proceso, se funde el hierro reducido. El gas de acoplamiento proveniente del gasificador de fusion (3) se utiliza como al menos una parte del gas de reduccion, el gas ligero sometido a reaccion es extraído del reactor de reduccion (1). A fin de que con mayor eficiencia energética y de materia prima, también aumente la productividad, obteniendo simultáneamente propiedades metalurgicas mejoradas del producto, se derive al menos una parte del gas ligero del conducto (9) destinado a extraer el gas ligero del reactor de reduccion (1) y se retorna a través de al menos un conducto de retorno (13, 18) que lleva al gasificador de fusion (3) y se hace ingresar en el gasificador de fusion (3). Reivindicacion 1: Procedimiento para la preparacion de metal fundido, en el que se hace ingresar oxígeno, un agente de reduccion y hierro reducido en un reactor de reaccion (1) , a un gasificador de fusion (3), el agente de reduccion se gasifica con el oxígeno y se funde el hierro reducido mediante el calor producido en la gasificacion, donde el gas de acoplamiento proveniente del gasificador de fusion (3) se utiliza como al menos una parte del gas de reduccion, y al menos una parte del gas ligero extraído se hace ingresar en el gasificador de fusion (3) y se condensa el gas retornado, caracterizado porque el gas retornado es enfriado entre la condensacion y el ingreso en el gasificador de fusion (3) y se reduce el contenido de dioxido de carbono, y/o porque al menos un caudal parcial del gas retornado es transformado con hidrocarburos más elevados y utilizando otro caudal parcial del gas retornado como gas combustible. Reivindicacion 9: Instalacion para la preparacion de metal fundido, con un reactor de reduccion (1) un gasificador de fusion (3) con suministro de oxígeno (5) y un sistema de suministro (4) para agentes de reduccion, al menos un conducto (6, 8) para el suministro del gas de acoplamiento proveniente del gasificador de fusion (3) dentro del reactor de reduccion (1) y al menos un conducto (9) para la extraccion del gas ligero fuera del reactor de reduccion (1), con al menos un conducto de retorno (13, 18) que se bifurca del conducto para el gas ligero y lleva hacia el gasificador de fusion (3) donde en el conducto de retorno (13, 18) se instala el condensador (14) , caracterizado porque entre el condensador (14) y el suministro de oxigeno (5) se instala un dispositivo refrigerante (16) y una etapa de reduccion de dioxido de carbono (17) y/o porque entre el condensador (14) y el suministro de oxígeno (5) se instala un reformador (21).
