摘要： The invention relates to a method for removing CO
2 from exhaust gases (9), such as exhaust gases from plants for producing raw iron or exhaust gases from syngas plants, wherein the CO
2 is removed by means of chemical and/or physical absorption (14), wherein the heat for regenerating the absorption agent is at least partially obtained from an air fractionation system (23). The CO
2 can thereby be separated from other gases from the exhaust gases to a greater degree than for pressure swing adsorption, and a lower-quality energy carrier can nevertheless be used therefor.

摘要： The invention relates to a method for producing molten material, wherein oxygen, reducing agents and iron that has been reduced in a reduction reactor are introduced into a melter gasifier (3). The reducing agent is gasified with the oxygen and the heat thereby produced melts the reduced iron. The coupling gas from the melter gasifier (3) is used at least as a portion of the reduction gas. Reacted top gas is withdrawn from the reduction reactor (1). The aim of the invention is to increase energy efficiency and raw material efficiency. For this purpose, at least a portion of the thermal energy of the top gas and/or of the portion of the reduction gas used as the cooling gas and surplus gas is used for indirectly heating at least one additional gas that is used in the method. At least one heat exchanger (15, 18, 21) is arranged in a line (9 and/or 23) for the top gas and/or the portion of the reduction gas used as the cooling gas and surplus gas, at least one additional gas used in the method flowing through said heat exchanger (15, 18, 21).

摘要： The invention relates to a method and a system for the method for using the exhaust gases of plants for raw iron manufacture for steam generation, wherein at least some of the exhaust gas is carried away as export gas (12) from the plant for raw iron manufacture and is thermally exploited by means of combustion, and wherein the exhaust gas from the combustion is supplied to a heat-recovery steam generator (29). In order to be able to use more energy from the export gas (12) for power generation, provision is made that the export gas (12) is fed into a combustion chamber (23) which is arranged upstream of the heat-recovery steam generator (29), and that heat is drawn from the export gas (12) after combustion in the heat-recovery steam generator (29), without the export gas (12) passing through a gas turbine between combustion and the heat-recovery steam generator, wherein the pressure in the combustion chamber (23) and the heat-recovery steam generator (29) is set above atmospheric pressure, particularly up to 3.5 bar
g , by a gas flow regulator (31) which is arranged downstream of the heat-recovery steam generator (29).

摘要： A method for melting raw iron in a blast furnace (1) operated with oxygen or in a melting reduction system, comprising a reduction region, wherein the scrubbed raw gas (GG, EG) removed from the reduction region is recirculated by adding hydrocarbons into the reduction region. According to the invention, the scrubbed raw gas (GG, EG) is mixed with hydrocarbons and is blended with reduction gas (REDG) that has a temperature over 1000°C and is obtained by the partial oxidation of hydrocarbons using oxygen gas having an oxygen content of more than 90 vol.% in order to form a recirculation gas (REZG) having a temperature over 800°C. The recirculation gas (REZG) is recirculated into the reduction region after an auto-reformation process.
