    摘要： A process for the direct reduction of iron ore when the external source of reductants is one or both of coke oven gas (COG) and basic oxygen furnace gas (BOFG). Carbon dioxide (CO2) is removed from a mixture of shaft furnace off gas, obtained from a conventional direct reduction shaft furnace, and BOFG. This CO2 lean gas is mixed with clean COG, humidified, and heated in an indirect heater. Oxygen (O2) is injected into the heated reducing gas. This hot reducing gas flows to the direct reduction shaft furnace for use. The spent hot reducing gas exits the direct reduction shaft furnace as shaft furnace off gas, produces steam in a waste heat boiler, is cleaned in a cooler scrubber, and is compressed and recycled to join fresh BOFG. A portion of the shaft furnace off gas is sent to the heater burners. The BOFG and COG are also employed for a variety of other purposes in the process.

    摘要： A method and apparatus for discharging cold product or a combination of cold and hot products from a continuous supply of hot direct reduced iron (“DRI”) comprising a product cooler connected to a shaft furnace, with downward movement of the hot DRI and upward concurrent flow of cooling gas through the product cooler. The method and apparatus provides for diverting of hot DRI from an upper portion of the cooler for gravitational transfer to an adjacent storage unit located at a lower elevation than the furnace. The product cooler is situated at a lower height in relation to the furnace, for gravity transfer of a continuous supply of hot DRI through an entry point into the cooler. Cooler provides for cooling gas injection into the lower portion of the cooler, with gas flow upward and counter-current to the hot DRI that descends through the cooler. Recovered cooling gas is scrubbed, cooled, and recycled back for injection into the bottom portion of the cooler. The cooled DRI is removed from the bottom portion of the cooler thereby establishing a gravitational movement of DRI through the cooler. Simultaneous to cooling of the DRI material, separate transfer portions of hot DRI material can be diverted at the top of the cooler with gravitational transfer to one or more adjacent storage units for processing.

    摘要： Methods and systems for producing direct reduced iron (DRI), comprising: generating a syngas stream in a carbon dioxide (CO2) and steam reformer; and providing the syngas stream to a direct reduction (DR) shaft furnace as a reducing gas stream. The methods and systems also comprise combining the syngas stream with a recycled off-gas stream from the DR shaft furnace to form the reducing gas stream. The methods and systems further comprise removing carbon dioxide (CO2) from the recycled off-gas stream from the DR shaft furnace prior to combining it with the syngas stream to form the reducing gas stream. The methods and systems still further comprise feeding CO2 removed from the recycled off-gas stream from the DR shaft furnace to the CO2 and steam reformer. The methods and systems still further comprise feeding recycled off-gas from the recycled off-gas stream from the DR shaft furnace to the CO2 and steam reformer.

    摘要： A method and apparatus for sequestering carbon dioxide from a waste gas and reusing it as a recycled gas without emissions concerns, including: given a gas source divided into a process gas and a waste gas: mixing the process gas with a hydrocarbon and feeding a resulting feed gas into a reformer for reforming the feed gas and forming a reducing gas; and feeding at least a portion of the waste gas into a carbon dioxide scrubber for removing at least some carbon dioxide from the waste gas and forming a carbon dioxide lean gas that is mixed with the reducing gas. Optionally, the method also includes feeding at least a portion of the waste gas into the carbon dioxide scrubber for removing at least some carbon dioxide from the waste gas and forming a fuel gas after the addition of a hydrocarbon that is fed into the reformer. Optionally, the gas source and the reducing gas are associated with a direct reduction process for converting iron oxide to metallic iron in a reduction furnace that utilizes the reducing gas, optionally after some modification, and produces the gas source.
