Definitions
- the invention relates to a method for the treatment of a carbon dioxide-containing flue gas stream, wherein from the flue gas stream at least a portion of the existing carbon dioxide is removed by forming a low-carbon gas stream and a carbon dioxide-rich gas stream by means of a laundry, and an apparatus for performing the method.
- Carbon dioxide-containing flue gas streams also accumulate in other large-scale combustion plants that are operated with fossil fuels. These include, for example, industrial furnaces, steam boilers and similar large-scale thermal power plants for electricity and / or Heat generation. It is conceivable that even in such systems, the carbon dioxide is separated from the flue gas streams by means of a laundry and a recovery or storage (eg by compression in the ground) is supplied.
- a carbon dioxide-rich gas stream is present, which is present in the water-saturated state. After precompression, this gas stream must be dried to meet the water content required for carbon dioxide-rich product streams. If, for example, the carbon dioxide-rich gas stream is to be supplied to a later use via pipelines, a water content of less than 500 ppmv is generally to be adhered to after final compression in order to prevent corrosion and hydrate formation.
- glycol wash includes an absorption column, a regenerating column, a series of heat exchangers, filters and pumps. Glycol washing also requires additional thermal energy for regeneration.
- the gas stream In order to separate water from the carbon dioxide-rich gas stream, the gas stream must be cooled below the dew point temperature of the water (depending on the pressure of the water-saturated gas). If this temperature is exceeded, the water condenses out and can be separated from the gas stream.
- the gas flow including the possibly injected glycol-water mixture should be able to be cooled to a temperature of below 10 ° C. at a pressure of> 30 bar, for example. This can not be realized in central European latitudes by cooling water (usual temperatures around 25 ° C). In order to provide a cooling medium with the required flow temperatures, therefore, the use of a refrigeration system, in particular a compression or absorption refrigeration system is proposed according to the invention.
- the absorption refrigeration system In contrast to a compression refrigeration system, the absorption refrigeration system has a significantly lower electrical energy consumption, since a pump can be used instead of a compressor. Therefore, according to a preferred embodiment of the invention for drying the carbon dioxide-rich and water-saturated gas stream after the laundry, an absorption refrigeration system is used.
- the absorption refrigeration system by means of thermal energy, in particular in the form of steam and / or district heating and / or direct firing, driven.
- the thermal energy is expediently from Brüdendampf one of the incineration and / or gasification upstream coal drying or Brüdenondesat (if the Brüdendampf is previously used in another process) won.
- Brüdendampf or vapor condensate from the coal drying is on a usable temperature level (> 100 0 C) as waste heat available.
- electrical energy is only necessary for the circulation pump of the solvent of the absorption refrigeration system. As a result, a considerable saving in electrical energy is achieved.
- the carbon dioxide-rich gas stream is preferably dried to a water content of less than 500 ppmv.
- the drying of the carbon dioxide-rich gas stream is expediently carried out at a pressure between 30 and 60 bara, preferably between 35 and 40 bara.
- the present invention is intended for the treatment of flue gases from conventional incinerators.
- the carbon dioxide-containing flue gas stream is formed in a large combustion plant in which fossil fuels are burned with combustion air.
- This flue gas stream is preferably subjected to a wash in an absorption column with subsequent detergent regeneration for the separation of carbon dioxide from the flue gas stream.
- the carbon dioxide is removed by means of a wash with a physically and / or chemically acting detergent from the carbon dioxide-containing flue gas stream.
- the detergent expediently contains as part of at least one amine.
- the carbon dioxide-rich gas stream is formed during a regeneration of a detergent used for washing, which contains at least one amine as a constituent.
- the carbon dioxide removed from the flue gas stream can finally be fed to a use or storage, in particular a compression in the underground, while the low-carbon gas stream can be delivered to the atmosphere with a significantly reduced climate-damaging effect.
- the invention further relates to a device for treating a carbon dioxide-containing flue gas stream with a washing device for washing at least a portion of the existing carbon dioxide from the flue gas stream to form a low-carbon gas stream and a carbon dioxide-rich gas stream.
- the stated object is achieved in that the washing device is followed by a refrigeration system for cooling and drying of the carbon dioxide-rich gas stream.
- a device for injecting glycols in particular a glycol-water mixture may additionally be provided.
- a particularly preferred embodiment of the device provides that the refrigeration system is designed as absorption refrigeration system.
- Refrigeration systems require significantly lower capital and operating costs compared to commonly used for drying molecular sieve adsorber stations or glycol washes.
- thermal energy advantageousously waste heat
- the energy requirements for drying can be significantly reduced. In place of the vapor of a brother, too
- Vapor condensate can be used if the vapor is already used in another process.
- the simple and robust construction is another advantage of using an absorption refrigeration system to dry the carbon dioxide rich and water saturated gas stream.
- the invention is suitable for all conceivable large combustion systems in which carbon dioxide-containing gas flows incurred. These include e.g. Fossil-fueled power plants, industrial furnaces, steam boilers and similar large-scale thermal power and / or heat generation plants. With particular advantage, the invention can be used in large combustion plants, which are supplied with air as a fuel gas. In particular, the invention is suitable for coal-fired power plants in which the CO2 is washed out of the flue gas and compressed in the underground (“CCS - Carbon Capture and Storage").
- the figure shows a block diagram of a treatment plant for a carbon dioxide-rich and water-saturated gas stream from a carbon dioxide scrubbing a coal power plant.
- a carbon dioxide-rich gas stream is separated from a carbon dioxide-containing flue gas of a coal-fired power plant, which is provided for storage in the underground.
- the carbon dioxide-rich gas stream is precompressed by means of a compressor 1 and then passed through a heat exchanger 2, where it is pre-cooled by means of cooling water KW. Subsequently, the injection of a glycol-water mixture, wherein the main part of the glycol from the Glykolaufhusung 7 comes (concentration of deposited in 5 glycol-water mixture).
- a subsequent heat exchanger 3 is then cooled further by means of the absorption refrigeration system 4.
- broth steam BD and vapor condensate BK from an upstream coal drying system are used.
- the condensed in the heat exchanger 3 as a result of cooling below the dew point of the water glycol-water mixture is separated in a subsequent condensate 5.
- the gas stream, which has been dried to a water content of less than 500 ppmv, is finally compressed in a final compressor 6 to the pressure intended for the further use of the gas stream (for example for pressing in the substrate).
