Abstract
Un método para producir hierro reducido directo que tiene mayor contenido de carbono, que comprende: proporcionar un chorro de gas rico en monóxido de carbono; y administrar el chorro de gas rico en monóxido de carbono a un horno de reducción directa y exponer parcial o completamente el óxido de hierro al chorro de gas rico en monóxido de carbono para aumentar el contenido de carbono del hierro reducido directo resultante. El chorro de gas rico en monóxido de carbono se entrega a una o más zonas de transición y una zona de enfriamiento del horno de reducción directa. Opcionalmente, proporcionar el chorro de gas rico en monóxido de carbono comprende inicialmente proporcionar uno de un chorro de gas reformado de un reformador y un chorro de gas sintético de una fuente de gas sintético. Opcionalmente, el chorro de gas rico en monóxido de carbono se deriva, al menos en parte, de una unidad de recuperación de monóxido de carbono que forma el chorro de gas rico en monóxido de carbono y un chorro de gas efluente. Opcionalmente, el método incluye, además, proporcionar un chorro de gas rico en hidrocarburos a una o más zonas de transición y una zona de enfriamiento del horno de reducción directa, con y/o separado del chorro de gas rico en monóxido de carbono.A method for producing direct reduced iron having a higher carbon content, comprising: providing a jet of gas rich in carbon monoxide; and administer the jet of carbon monoxide-rich gas to a direct reduction furnace and partially or completely expose the iron oxide to the jet of carbon monoxide-rich gas to increase the carbon content of the resulting direct reduced iron. The jet of carbon monoxide-rich gas is delivered to one or more transition zones and a direct reduction furnace cooling zone. Optionally, providing the jet of carbon monoxide-rich gas initially comprises providing one of a reformed gas stream of a reformer and a synthetic gas stream of a synthetic gas source. Optionally, the jet of carbon monoxide-rich gas is derived, at least in part, from a carbon monoxide recovery unit that forms the jet of carbon monoxide-rich gas and a stream of effluent gas. Optionally, the method further includes providing a jet of hydrocarbon-rich gas to one or more transition zones and a direct reduction furnace cooling zone, with and / or separated from the jet of carbon monoxide-rich gas.
