Definitions
- Pig iron production plants For the production of pig iron, which also includes the production of pig iron-like products, there are essentially two known common processes: the
- the blast furnace process first produces pig iron from iron ore using coke. In addition, scrap can also be used. Thereafter, steel is produced by further processes from pig iron.
- the iron ore is used as lump, pellets or sinter together with the reducing agents (usually coke, or coal, for example in the form of a
- Fine coal indisposition plant Fine coal indisposition plant
- other constituents limestone, slag formers, etc.
- the blast furnace is a metallurgical reactor in which the Möllerklax reacts in countercurrent with hot air, the so-called hot blast.
- hot blast By burning the carbon from the coke, the necessary heat for the reaction and carbon monoxide or hydrogen, which is a significant part of the reducing gas and flows through the Möllerklale and reduces the iron ore.
- the result is pig iron and slag, which are tapped periodically.
- oxygen blast furnace which is also referred to as blast furnace with top or top gas recirculation, in the gasification of coke or coal oxygen-containing gas with more than 90% oxygen content (0 2 ) in the blast furnace
- a gas cleaning For the emerging from the blast furnace gas, the so-called top or top gas, a gas cleaning must be provided (for example, dust and / or cyclones in combination with
- the oxygen blast furnace usually a compressor, preferably with aftercooler, for in the blast furnace
- Blast furnace methods are a heater for the reducing gas and / or a combustion chamber for partial combustion with oxygen.
- the disadvantages of the blast furnace are the demands on the feedstock and the high emission of carbon dioxide.
- the iron carrier used and the coke must be lumpy and hard, so that sufficient cavities remain in the Möllerklale, which ensure the flow through the blown wind.
- the C0 2 output represents a strong

- Pressure swing adsorption is a physical process for the selective decomposition of gas mixtures under pressure.

- Recyclable material here CO, H 2 , CH 4
- Recyclable material flows freely through the column. Once the adsorbent is fully loaded, the pressure is released and the column rinsed.
- electrical power is required for the prior compression of the C0 2 rich recycle gas.
- the product gas stream after the pressure swing adsorption which contains the recyclables, contains in exhaust gases from the
- Pig iron production still about 2-6 vol% CO 2 .
- the residual gas stream from the (V) PSA plant still contains relatively high reducing gas constituents (such as CO, H 2 ), which are lost for pig iron production.
- the residual gas stream after pressure swing adsorption which contains the undesirable components, is typically composed of exhaust gases from pig iron production as follows:
- the residual gas can not simply be thermally recycled because it - due to the low and / or fluctuating
- CCPP combined cycle power plant
- Boiler would increase the flame temperature during the
- Combustion can be reduced.
- the residual gas must be compressed so that the CO2 is in liquid form, and then the liquid CO2 must be placed in a reservoir, to which the pressure must usually be increased so far that the CO2 in the liquid-solid or supercritical state, where CO2 has a density of about 1000 kg / m 3 .
- the supercritical state is a state above the critical point in the phase diagram (see FIG. 1) which is characterized by the equalization of the densities of the liquid and gas phases. The differences between the two
- High-power compressor can be used to bring the typical densities at line level, which is in the range of greater than 0 ° C and greater than 70 bar (7,000,000 Pa), preferably 80-150 bar at ambient temperatures.
- the residual gas from a (V) PSA is not suitable for being bound because, in addition to CO2, it has a relatively high proportion of CO, H 2 , N 2 , CH 4 , etc.
- the CO content poses a safety risk, as this can lead to a risk of injury to persons (CO poisoning) and, under certain circumstances, to inflammation or explosion.

- the CO, H 2 , CH 4 fraction recovered from the pig iron production can be increased over (V) PSA and the C0 2 fraction in the product gas can be substantially reduced (up to a few ppmv).
- the residual gas stream consists mainly of CO2 and can therefore be used for
- Vacuum compressors are needed, which also consume a lot of energy and cause high maintenance costs.
- the low energy consumption is an advantage especially for those countries where energy is scarce and / or expensive.
- Absorption processes are comparable to those for a VPSA plant. But the absorption process needs large amounts of low-pressure steam with a pressure of more than 2 bar g or higher, eg 10 bar g . This steam would be expensive if it had to be specially made and could not be taken from an existing steam source.
