Abstract

Un proceso de reducción directa que produce DRI a partir de partículas de óxido de hierro mediante la reducción a aproximadamente 750ºC con un gas reductor principalmente H₂ y CO, que también incluye CO₂, H₂O y metano, al reactor de reducción y divide el efluente del gas superior proveniente de la reacción de reducción después de la refrigeración/depuración. La primera porción de gas superior resultante con un primer gas auxiliar que contiene hidrocarburo pasa a través de un reformador catalítico que produce un efluente del primer gas reductor caliente mejorado. La segunda porción del gas superior pasa a través de una unidad de eliminación de CO₂ y luego con el segundo gas auxiliar que contiene hidrocarburos pasa a través de un calentador que produce un efluente del segundo gas de reciclado reductor pobre en CO₂ caliente. El primer y segundo efluentes se incorporan en la zona reductora del reactor de reducción como el reactante del gas reductor. El caudal de flujo de al menos la segunda de los dos gases auxiliares se requiere para controlar el contenido del carbono del DRI producido.
