Abstract

Método para producir hierro reducido directo (DRI) comprende generar un chorro de gas sintético en un reformador de dióxido de carbono (CO₂) y vapor; y proporcionar el chorro de gas sintético a una caldera de cuba para reducción directa (DR) como un chorro de gas reductor, comprende también combinar el chorro de gas sintético con un chorro de gas liberado reciclado de la caldera de cuba de DR para formar el chorro de gas reductor, comprende además retirar el dióxido de carbono (CO₂) del chorro de gas liberado reciclado del horno de cuba para DR antes de combinarlo con el chorro de gas sintético para formar el chorro de gas reductor, incluso comprende, alimentar el CO₂ retirado del chorro de gas liberado reciclado de la caldera de cuba para DR al reformador de CO₂ y vapor, incluso comprende, además, alimentar el gas liberado reciclado del chorro de gas liberado reciclado de la caldera de cuba para DR al reformador de CO₂ y vapor. Reivindicación 12: Un sistema para producir hierro reducido directo (DRI), que comprende: un reformador de dióxido de carbono (CO₂) y vapor para generar un chorro de gas sintético; y un conducto para proporcionar el chorro de gas sintético a una caldera de cuba para reducción directa (DR) como chorro de gas reductor.Method for producing direct reduced iron (DRI) comprises generating a stream of synthetic gas in a carbon dioxide (CO₂) and steam reformer; and providing the synthetic gas jet to a direct reduction (DR) tank boiler as a reducing gas stream, it also comprises combining the synthetic gas stream with a recycled released gas stream from the DR tank boiler to form the reducing gas jet, further comprising removing the carbon dioxide (CO₂) from the recycled released gas jet of the DR furnace before combining it with the synthetic gas jet to form the reducing gas jet, even comprising feeding the CO₂ removed from the jet of gas released recycled from the Cuba boiler for DR to the reformer of CO₂ and steam, it also includes, in addition, feed the gas released recycled from the jet of gas released recycled from the kettle of DR for the DR reformer of CO₂ and steam . Claim 12: A system for producing direct reduced iron (DRI), comprising: a carbon dioxide (CO₂) reformer and steam for generating a stream of synthetic gas; and a conduit for providing the synthetic gas jet to a direct reduction (DR) tank boiler as a reducing gas jet.
