Abstract
Способ и устройство для секвестрации диоксида углерода из отработанного газа и его повторного использования в качестве рециркулирующего газа без осложнений, связанных с выбросами, включающие, при условии, что источник газа разделен на технологический газ и отработанный газ, смешивание технологического газа с углеводородом и подачу полученного в результате сырьевого газа в установку риформинга для риформинга сырьевого газа и образования восстановительного газа; подачу по меньшей мере части отработанного газа в скруббер для очистки от диоксида углерода для удаления, по меньшей мере, некоторого количества диоксида углерода из отработанного газа и образования бедного по диоксиду углерода газа, смешиваемого с восстановительным газом. Необязательно, способ также включает подачу по меньшей мере части отработанного газа в скруббер для очистки от диоксида углерода для удаления, по меньшей мере, некоторого количества диоксида углерода из отработанного газа и образование топливного газа после добавления углеводорода, подаваемого в установку риформинга. Необязательно, источник газа и восстановительный газ связаны с процессом прямого восстановления для преобразования оксида железа в металлическое железо в восстановительной печи, использующей восстановительный газ, необязательно после некоторой модификации, и образующей источник газа.A method and apparatus for the sequestration of carbon dioxide from flue gas and its reuse as recycle gas without complications associated with emissions, including, provided that the gas source is divided into process gas and flue gas, mixing the process gas with the hydrocarbon and supplying it to the result of the raw gas in the reforming unit for reforming the raw gas and the formation of a reducing gas; supplying at least a portion of the exhaust gas to a carbon dioxide scrubber to remove at least some carbon dioxide from the exhaust gas and to form carbon dioxide-poor gas mixed with the reducing gas. Optionally, the method also includes feeding at least a portion of the exhaust gas to a scrubber for purifying carbon dioxide to remove at least some carbon dioxide from the exhaust gas and forming fuel gas after adding the hydrocarbon fed to the reformer. Optionally, a gas source and a reducing gas are associated with a direct reduction process for converting iron oxide to metallic iron in a reduction furnace using a reducing gas, optionally after some modification, and forming a gas source.
