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.

摘要： The present invention provides a method and apparatus for charging hot direct reduced iron (HDRI) from hot transport vessels (HTVs) into a melter or finisher. In general, the apparatus includes a charging stand including a plurality of bays for receiving and supporting a plurality of HTVs. Each HTV includes at least an outlet port. This outlet port is configured to engage an inlet port of one of the plurality of bays of the charging stand via a telescoping seal that provides a substantially air-tight seal. A feed device is provided that moves the HDRI disposed within the HTVs from the outlet port/inlet port interface to a melter or finisher, such as an electric arc furnace (EAF) or the like. The charging stand also includes one or more load cells operable for weighing the HTVs and the HDRI disposed therein, such that a computer or other logic may be used to control the feed rate of the HDRI charged into the melter or finisher.
