Abstract
Настоящее изобретение относится к способу прямого восстановления железной руды, выполняемому посредством агрегата, включающего гравитационную печь (2), которая имеет по меньшей мере одну зону (8) восстановления железной руды в верхней части вышеупомянутого и по меньшей мере одну зону (9) отложения углерода и одну зону (10) охлаждения восстановленного металла в нижней части вышеупомянутого и средства загрузки восстановительной газовой смеси в реактор в соответствии с зоной восстановления, средства для повторного использования выпуска или отходящего из реактора реакторного газа для синтез-газа и смешивание рециркулирующего газа с природным газом для образования восстановительной газовой смеси. В соответствии с изобретением на первой стадии (5) преобразования не вступивший в реакцию моноксид углерода СО и пар, присутствующий в отходящем реакторном газе, преобразуют в двуокись углерода и водорода в соответствии с реакцией конверсии водяного газа СО+HO=CO+Н, на второй стадии преобразования обезвоженный отходящий реакторный газ, включающий в основном диоксид углерода и водород, обрабатывают для удаления диоксида углерода и на третьей стадии преобразования выполняют физическое разделение и азота, и оксида углерода от восстановительного синтез-газа для снижения уровней СО и любых существующих в рециркулирующем газе других газов до такого низкого уровня, насколько это возможно, чтобы рециркулирующий восстановительный газ являлся насколько это возможно приближенным к чистому водороду H.
