Definitions
- the invention relates to a process for purifying a carbon dioxide-containing gas stream, wherein the gas stream is first subjected to a prewash in a lower section of an absorption column for conditioning the gas stream and then in an upper section of the absorption column the carbon dioxide is at least partially washed out with a washing liquid from the gas stream, and a device for carrying out the method.
- power plants ie industrial installations for providing in particular electrical and partly additional thermal power
- primary energy is used, which is made available after appropriate conversion as useful energy.
- gas streams are generated which can not be released to the environment without further purification steps.
- fossil fuels e.g. Coal, petroleum or natural gas, burned
- flue gases e.g. CO2
- waste gas streams containing environmentally harmful components.
- pollutant component is increasingly considered CO2, which is classified as a harmful gas.
- CCS Carbon, Capture and Sequestration
- Carbon dioxide-containing gas streams also accrue to other pyrolysis plants operated with fossil fuels. These include, for example, industrial furnaces, Steam boilers and similar large-scale thermal plants for generating electricity or heat.
- amine-based detergents can be used.
- the flue gas stream In order to make the washing process as efficient as possible, the flue gas stream must be conditioned accordingly before entering the actual washing section. For this purpose, the flue gas stream must be cooled down to the appropriate temperature.
- traces of harmful ingredients such as SO 2 must be removed from the flue gas stream before the actual CO 2 scrubbing. This is usually done with the help of a pre-wash with water and optionally basic additives (depending on the traces and their content).
- the prewash can be set up as a separate apparatus or integrated as an additional apparatus in the actual laundry.
- prewash and wash column For example, a separate installation of the prewash requires a large plant floor space. In addition, due to the necessary additional piping an additional pressure loss occurs. Finally, the gas distribution must be considered twice on a large column cross-section (prewash and wash column).
- Object of the present invention is to provide a method of the type mentioned above and an apparatus for performing the method in such a way that a technical construction of the absorption column is realized in an economical manner
- This object is achieved procedurally according to the invention that the entire, loaded with the washed carbon dioxide scrubbing liquid withdrawn from the absorption column and fed to a arranged outside the absorption column storage tank and then fed to a scrubbing liquid pump, which pumps the scrubbing liquid to a detergent regeneration stage.
- the prewashing is carried out in a section of the absorption column designed as the lowest absorber bed.
- the absorption column comprises e.g. a total of four absorption beds, wherein the uppermost absorption bed is used for backwashing, while the two central absorption beds for the actual leaching of the
- Carbon dioxide are provided.
- the lowermost absorption bed is used for prewashing the carbon dioxide-containing gas stream entering the absorption column in the bottom region.
- a physically and / or chemically acting detergent is used for the washing liquid for the separation of carbon dioxide.
- a detergent which contains at least one amine is suitable for this purpose.
- the gas stream to be purified is formed by a carbon dioxide-containing exhaust gas stream of a large combustion plant, in particular a power plant, wherein fossil fuels are burned with air in the large combustion plant.
- the leached carbon dioxide can be treated and sent for use and / or storage.
- the carbon dioxide can be transported, for example via pipelines to a site and pressed there in rock layers of the subsurface or salt water bearing layers.
- the wash is preferably carried out at about atmospheric pressure, in particular at a pressure between -100 mbar and +100 mbar.
- the washing is advantageously carried out at a temperature in the range of 20 to 80 0 C, more preferably in the range of 30 to 45 0 C.
- Wash water circulation prewash is conveniently cooled by means of cooling water or cold water from a refrigeration system.
- all liquids from intermediate withdrawals in particular side draws and intermediate circulations, and bottom withdrawals of the absorption column can be fed to further feed containers.
- the storage container is used as a collecting reservoir for the detergent of the entire system (the so-called hold-up).
- the invention further relates to an apparatus for purifying a carbon dioxide-containing gas stream with an absorption column having a lower portion for prewashing the gas stream and an upper portion for at least partially leaching the carbon dioxide from the gas stream.
- the stated object is achieved in that the absorption column is connected via at least one liquid withdrawal with a arranged outside the absorption column feed tank in connection, which is followed by a washing liquid pump.
- all liquid withdrawals of the absorption column can be connected to further storage containers.
- the prewash section of the gas stream is formed from the lowermost absorption bed of the absorption column.
- the absorption column expediently has a diameter of at least 3 m, in particular 10 to 25 m, or equivalent rectangular cross section.
- the invention is suitable for all conceivable large combustion systems in which carbon dioxide-containing gas flows incurred. These include, for example, power plants powered by fossil fuels, industrial furnaces, steam boilers and similar large-scale thermal plants for power and / or heat generation. In particular, the invention is suitable for so-called low-CO 2 coal power plants after the post-combustion capture process.
- the figure shows an absorption column with integrated prewash.
- the carbon dioxide-containing flue gas from a coal power plant is introduced via line 2 into the lower section 3 of the absorption column 1.
- an absorption bed 4 is arranged, which represents one of a total of four absorption beds 4,5,6,7 of the absorption column 1.
- a prewash of the gas stream takes place, in which the gas stream is cooled to the desired temperature for the actual CO 2 scrubbing of about 30 to 35 ° C and largely free of traces of harmful ingredients, in particular SO 2 .
- water possibly with basic additives, such as ammonium compounds, trickled over the absorbent bed 3.
- the thus pre-cleaned and cooled gas stream is subjected in the overlying section 8 of the absorption column 1 of the actual CO 2 scrubbing.
