Definitions
- the invention relates to a method for burning fuels containing metal or metal oxides, e.g. Coke, coke residue or distillation residues from petroleum refineries, especially petroleum coke or pyrolysis coke.
- metal or metal oxides e.g. Coke, coke residue or distillation residues from petroleum refineries, especially petroleum coke or pyrolysis coke.
- the invention now aims to provide a method of the type mentioned at the outset, with which even highly contaminated and heavy metal-containing fuels, in particular refinery residues or petroleum coke, can be used in an appropriate amount without restriction, so that it is possible on the one hand to utilize such inferior carbon carriers and on the other hand to use them Possibility is created to safely utilize the heavy metal components and the sulfur content of such fuels and to keep them out of the subsequent operation, for example of a clinker furnace or a conversion plant.
- the method according to the invention essentially consists in that the feed material to be burned is introduced and gasified into a liquid, carbon-dissolving metal bath, in particular a pig iron bath with a carbon content of more than 2.5% by weight and a calcareous slag the metal bath air, oxygen, water vapor and / or CO 2 is introduced in an amount which ensures that the carbon saturation in the metal bath is below and kept above 2.5% by weight, and that the gasification product is withdrawn. Because the fuel is introduced into a liquid metal bath, in particular as an iron bath, rapid and efficient gasification is achieved, with a corresponding amount of oxygen for the formation of carbon monoxide being supplied for this gasification and through the metal bath is passed through.
- a liquid metal bath in particular as an iron bath
- the carbon content of the metal bath and in particular the iron bath must always be below the saturation limit is essential for the process according to the invention, so that carbon can also be absorbed from the carbon wastes or the feed material to be burned in the metal bath and subsequently gasified can.
- the gasification usually takes place by reacting the bath carbon content with the oxygen and it must therefore be ensured in every phase of the operation that the bath is also able to dissolve carbon.
- Suitable conversion to combustible product gases can be carried out with oxygen and / or water vapor and / or CO 2.
- the metal bath must therefore be selected from the group of metals which are able to dissolve significant amounts of carbon. This is especially true for iron baths.
- carbon can also be dissolved to a relatively high degree in nickel baths and in chrome baths and gasified by reaction with oxygen, for example by blowing air.
- Possible reactors are, for example, bottom-blowing, inflating and combined blowing converters, for example OBM, LD, K-OBM, AOD . or also metallurgical pans.
- the gasification product Because now only the gasification product is burned, a product that has been cleaned of heavy metals is introduced into the subsequent combustion process, so that pollutants do not get into the clinker, particularly when the gasification product is preferably used for firing clinker furnaces.
- the heavy metals are in such a procedure in Metal bath or dissolved in the iron bath and form a corresponding metal regulation there.
- high amounts of sulfur can be eliminated by introducing a pig iron bath with a carbon content of more than 2.5% by weight and a calcareous slag.
- the calcareous slag retains the sulfur of the feed, primarily calcium sulfite being formed, whereas the metal regulation contains heavy metals such as vanadium and nickel in metal or in the form of carbides.
- the regulus formed which contains nickel and vanadium, advantageously being subsequently worked up metallurgically.
- the alkali (Na, K) entered with the feed materials to be gasified, such as petroleum coke or pyrolysis coke, are also slagged, so that alkali circuits are prevented in a downstream clinker furnace.
- sulfur is kept completely in the slag when carrying out the process according to the invention, wherein it is advantageously subsequently carried out in such a way that the slag formed is atomized with steam, H2S and SO2 being drawn off and the slag thus regenerated being blown into the metal bath together with the feed material.
- a slag that has been freed of H2S and SO2 in this way can be used again as a synthetic, high-purity regenerated slag, whereby local overheating in the area of floor nozzles can also be effectively prevented due to the procedure in which the carbon content in the bath is kept within defined limits.
- the gasification takes place by converting the carbon dissolved in the iron bath to carbon monoxide, and the corresponding regulation can simultaneously adjust the carbon content of the iron bath to ensure the desired reduction and carbide formation of the heavy metals.
- the slag basicity (CaO / SiO 2) of the calcareous slag is advantageously kept between 1.2 and 1.6, which ensures safe desulfurization of the metal regulation and the synthesis gas.
- the slag basicity can be adjusted to the desired basicity by adding clinker, lime or marl.
- the process according to the invention can be carried out successfully at temperatures between 1460 ° and 1730 ° C., whereby the correspondingly hot synthesis gas can be subjected to water vapor, as a result of which cooling takes place and after the reaction CO + (H20) Quenche -s—- CO 2 + H2 water gas is formed.
- the hydrogen-rich gas can be easily cleaned of the CO2 formed, for example using a basic wash or using a monoethanolamine solution.
- the soot formed in the absence of water during indirect cooling can be removed using a cyclone or filter.
- the almost complete absence of sulfur of the gas is essential for the reusability of the product gas, whereby H2S, COS and SO2 were only observed in negligible amounts and in some cases even outside the detection limit.
- the CO or CO2 content can of course be selected accordingly, the product gas being able to be used directly, for example, in a refinery for heating purposes. Due to its high purity, the gasification product is also particularly suitable for firing clinker stoves. Instead of a solid fuel burner with which petroleum coke is introduced, a gas burner is thus used in the present case, the corresponding gasification product being able to be supplied via a central duct and the combustion or cooling air being able to be supplied via a jacket duct.
- the feed is introduced into the metal bath with additives consisting of regenerated slags and / or CaCO3 via floor nozzles and that oxygen is used to gasify the C to CO dissolved in the metal bath in amounts of over 2.5% by weight the metal bath is introduced, the gasification product advantageously being able to be partially burned to maintain a bath temperature of> 1460 ° C.
- the heat required in the iron bath can of course also be introduced via electrode processes, such as graphite electrodes, whereby here, too, with regard to the relatively small upstream device for gasifying the petroleum Kokses with relatively small-scale facilities that can be found.
- the ash portion is composed essentially of SiO 2, Al 2 O 3, CaO, e 2 O 3, alkalis and traces of precious metals such as platinum, cobalt and palladium.
- a regulus was obtained which contained 38% by weight vanadium, 6.3% by weight nickel and, in addition to traces of sulfur, the noble metals mentioned above.
- the rest of the Regulus consisted of iron and carbon. Vanadium is predominantly bound to carbides. The Regulus obtained can be used as a feed in the vanadium processing industry.
- the product gas can be burned in separate burners.
- the gas space above the metal and slag bath can be used as a combustion chamber, whereupon the hot combustion gases can be used to use their waste heat.
- the process according to the invention succeeds in refining residues such as petroleum coke, tars, heavy oil and Pyrolysis coke, which is characterized by a relatively low or no hydrogen content, to directly obtain hydrogen gas, for which a hydrogenating gasification in an iron bath with addition of steam in the bath or in the gas phase is used.
- Complete desulfurization is achieved by means of the proposed synthetic slags, such slags being able to be largely recycled and heavy metals being kept in the iron bath by the process.
- the glazed slags can also advantageously be used as a binder component.
- Method for burning fuels containing metal or metal oxide e.g. Coke, coke residues or distillation residues from petroleum refineries, in particular petroleum coke
- metal or metal oxide e.g. Coke, coke residues or distillation residues from petroleum refineries, in particular petroleum coke
- the feedstock to be burned is introduced and gasified in a liquid, carbon-dissolving metal bath, in particular a pig iron bath with a carbon content of more than 2.5% by weight and a calcareous slag is that air, oxygen, water vapor and / or CO2 is introduced into the metal bath in an amount which ensures that the carbon saturation in the metal bath is below and held above 2.5% by weight, and that the gasification product is withdrawn.
