Abstract

Un proceso de reducción directa para producir DRI a partir de partículas que tienen óxidos de hierro con un gas reductor compuesto principalmente de H2 y CO, que incluye también CO2, H2O y metano. El gas efluente del reactor es dividido en dos porciones después de enfriarse/lavarse. Se agrega una primera corriente de gas de repuesto conteniendo hidrocarburos a la primera porción de gas efluente del reactor y la corriente combinada de gases pasa por un reformador catalítico para producir una primera corriente de gas reductor caliente. La segunda porción de gas efluente del reactor pasa por una unidad separadora de CO2 a la cual se agrega una segunda corriente de gas de repuesto conteniendo hidrocarburos y la corriente de gas combinada pasa por un calentador para producir una segunda corriente de gas reductor :aliente con baja concentración ce CO2. La primera y segunda corrientes de gas reductor caliente se alimentan como gas reductor a la zona de reducción del reactor de reducción. Se regula el flujo de por lo menos la segunda de las dos corrientes de gas de repuesto conteniendo hidrocarburos para controlar el contenido de carbono en el DRI producido.
