Definitions

  • the invention relates to a process for the combined production of pig iron and a synthetic gas-based organic chemical product.
  • the invention is based on a method in which the process gases of the steelworks are used materially.
  • a synthesis gas is first generated, which is then reacted in a synthesis plant to form an organic chemical product.
  • Such combined processes are composite systems in which the by-products of one process form feedstocks of another process.
  • the organic chemical product contains chemical compounds based on carbon. This chemical product is produced on the basis of a H 2 and CO-containing synthesis gas.
  • the synthesis gas is used for example for the production of methanol or fuels by Fischer-Tropsch synthesis. An oxo synthesis can also be used.
  • US 4 013 454 describes a process for the combined production of iron and methanol. It is fed to a blast furnace pure oxygen. The result is a blast furnace gas containing about 80% carbon monoxide and 20% carbon dioxide.
  • the object of the invention is to provide a process for the combined production of pig iron and a synthesis gas based on organic chemical product, which allows optimal recycling and can be realized with the lowest possible investment costs.
  • Material recycling should be as energy efficient as possible, so that the operating costs of the process are low.
  • This object is achieved in that air is supplied to a blast furnace and the nitrogen-containing blast furnace gas stream leaving the blast furnace is converted, in which carbon monoxide is reacted with usually provided as steam H 2 0 to hydrogen and carbon dioxide, wherein in a gas separation device, a hydrogen-containing material flow separated from a nitrogen-containing stream and the hydrogen-containing stream is fed to a synthesis plant.
  • the carbon monoxide contained in the top gas is first reacted with water vapor to form hydrogen and carbon dioxide.
  • This is preferably a catalytic CO conversion.
  • the gas mixture is fed to a gas separator.
  • this is a pressure swing adsorption system (PSA: Pressure Swing Adsorption).
  • PSA Pressure Swing Adsorption
  • a hydrogen flow is separated from a nitrogen-containing gas stream.
  • the hydrogen stream serves as the basis for providing a synthesis gas, which is then converted to the organic chemical product.
  • the gas separation device can also be designed as a membrane separation system.
  • the process can use blast furnace gas from an air blast furnace. This is made possible by an efficient and cost-effective removal of the nitrogen.
  • the conversion avoids complex separation of CO and nitrogen.
  • hydrogen is generated, which is used to provide the synthesis gas.
  • the pig iron can be further processed in a known manner with a steel converter to steel.
  • oxygen is preferably supplied to the steel converter, the converter gas stream leaving the steel converter being supplied to the hydrogen-containing material stream for the formation of a synthesis gas stream. It may thus provide a combined process whose final product is steel and at least one synthesis gas-based organic product.
  • the conversion of the top gas is carried out with low-pressure steam. It proves to be advantageous if the conversion is carried out at an absolute pressure of less than 10 bar, preferably at a pressure of 2 to 8 bar. In this way, the hydrogen required for the synthesis can be provided at low cost, since the feed gas does not have to be first compressed to a pressure of 20 to 50 bar for the CO conversion, as in conventional processes. Hydrogen is obtained on the pressure side of the pressure swing adsorption system, while nitrogen and optionally carbon dioxide are obtained on the expansion side. In the method according to the invention can thus be a further compression of about 50% of the total amount of gas used can be saved, since the nitrogen contained in the topping gas is already removed at a pressure of 2 to 8 bar from the feed gas stream. This reduces the operating and investment costs.
  • the converted blast furnace gas stream is first fed to an arrangement in which carbon dioxide is separated from hydrogen and nitrogen.
  • This arrangement is upstream of the gas separation device for the separation of hydrogen and nitrogen.
  • This arrangement may be a CO 2 pressure swing adsorption plant that separates carbon dioxide from hydrogen and nitrogen.
  • This CO 2 pressure swing adsorption plant is connected upstream of the H 2 pressure swing adsorption plant.
  • carbon dioxide is separated from nitrogen in a gas scrubber.
  • the gaseous mixture of nitrogen and carbon dioxide leaving the H 2 pressure swing adsorption plant is fed to a gas scrubber where carbon dioxide is separated from nitrogen.
  • this is an amine wash.
  • the carbon dioxide may serve as a source to provide the carbon content for the desired organic chemical product.
  • This carbon dioxide can be converted with hydrogen to carbon monoxide and water.
  • a converter is supplied with oxygen, wherein a converter gas is formed, which consists for the most part of carbon monoxide and some carbon dioxide.
  • the converter gas serves as carbon source for the organic chemical product. It proves to be particularly advantageous if the converter gas is compressed to a pressure level at which the hydrogen stream leaves the gas separation device.
  • a compressor is used, which brings the converter gas to the pressure level of the pressure side of the gas separation device.
  • the output from the gas separator hydrogen is, together with the converter gas by means of another compressor to that for the Synthesis of the organic chemical product required pressure level brought.
  • a pressure level of less than 60 bar and more than 40 bar is set.
  • the inventive method makes it possible to use untreated converter gas, so that no further effort for processing is required.
  • coke oven gas from a coke oven battery is used together with blast furnace gas to provide the synthesis gas. It proves to be particularly advantageous if the coke oven gas is fed to a pressure swing adsorption, in which hydrogen is separated from a residual gas. The hydrogen contained in the coke oven gas is separated and preferably added to the converter gas.
  • the residual gas produced during the pressure swing adsorption consists to a large extent of CO and CH 4 and is therefore a highly caloric gas which can be used extremely advantageously in the energy network of an integrated steelworks.
  • a synthesis gas based on top gas in combination with a converter gas and a coke oven gas allows a flexible mode of operation, in which the ratio of hydrogen to carbon monoxide is specifically adjustable.
  • a stream which contains hydrogen of the converted blast furnace gas and another mixed gas.
  • the mixed gas consists of converter gas, and possibly hydrogen of the coke oven gas.
  • This stream can be compressed by means of a common compressor from a pressure level of 2 to 8 bar outlet pressure to the required pressure for the synthesis of about 40 to 50 bar.
  • the stream is subjected to desulfurization before the synthesis plant.
  • the coke oven gas in the plant network according to the invention can also be used by being purified, subjected to hydrogenation, desulphurized and finally fed to a reformer.
  • the methane contained in the coke oven gas is converted to carbon monoxide and hydrogen.
  • the carbon monoxide and the hydrogen are then combined with the hydrogen obtained from the top gas, so that a suitable synthesis gas for the production of the organic chemical product is formed.
  • the carbon dioxide obtained from the converted top gas is preferably combined with converter gas of a steel converter and then compressed together.
  • the proportion of the converter gas supplied from the topping gas carbon dioxide is determined by the type of synthesis plant provided.
  • a nitrogen-containing gas stream is discharged from the synthesis plant and led to the conversion. In H 2 pressure swing adsorption, this nitrogen is then removed from the circulation. As a result, an enrichment of nitrogen in the synthesis cycle is prevented.
