Abstract

Proceso de reducción directa y planta para producir DRI que consiste en un reactor de reducción y al menos un calentador de gas reductor que comprende una sección de calentamiento por convección y una sección de calentamiento por radiación para elevar la temperatura del gas reductor a un nivel adecuado para la reducción de óxidos de hierro a hierro metálico, típicamente por sobre los 850ºC, donde el gas reductor provisto al reactor de reducción comprende una corriente de gas reductor reciclado a partir del reactor de reducción y una corriente auxiliar de gas de horno de coque que contiene compuestos de carbono que pueden formar depósitos de carbono en la ruta de calentamiento de dicho calentador, por ejemplo BTX y otros compuestos complejos de carbono. El calentador está provisto de medios para proveer agentes oxidantes, por ejemplo vapor, vapor y aire y/u oxígeno en tubos de calentamiento predeterminados en forma sucesiva para eliminar los depósitos de carbono que se puedan formar dentro de los tubos de calentamiento de dicho calentador sin interrumpir la operación de la planta. La corriente auxiliar de COG frío se puede combinar con el gas reciclado en un punto de la ruta de calentamiento del gas del calentador donde los tubos tienen una temperatura de pared de piel de al menos 700ºC, o cuando la mezcla de gas reciclado y COG se encuentra a una temperatura por encima de los 700ºC para minimizar la obturación o la contaminación o suciedad del equipo calentador.
