Definitions

  • the invention relates to the field of environmental protection and can be used in vehicles, in industrial, civil and other facilities to capture carbon dioxide, then carbon dioxide, or carbon dioxide, or CO2, followed by its decarbonization by burial or processing.
  • Carbon dioxide continues to build up in the atmosphere at a rate of about 40 gigatonnes per year. To achieve the goals set by the agreement, it will be necessary to reduce emissions - this is a necessary component of the "carbon neutrality" strategy in any country.
  • IPCC Intergovernmental Panel on Climate Change
  • Greenhouse gases in addition to carbon dioxide, also include methane and nitrous oxide, which destroy the stratospheric ozone layer, which protects us from the harmful effects of ultraviolet sunlight. It accounts for about 6% of the radiative forcing of long-lived greenhouse gases. Nitrous oxide is 300 times more greenhouse gas than carbon dioxide.
  • Power plants are the first candidates for capturing CO2.
  • the following capture technology options and applications are available.
  • a way to efficiently capture CO2 is to create a concentrated high pressure CO2 stream that can be easily transported to a storage location. Although the entire gas stream containing low concentrations of CO2 can be transported and injected underground, energy costs and other associated costs generally make such an approach impractical. Therefore, for transportation and storage purposes, it is necessary to create an almost pure CO2 stream.
  • CO2 separation applications are already in operation today in large industrial plants, including those for natural gas processing and ammonia production. At present, CO2 is generally absorbed to clean up other industrial gas streams. Absorption is used for storage purposes in only a few cases; most often CO2 is emitted into the atmosphere. Capture processes have always been used to obtain commercially viable amounts of CO2 from flue gas streams resulting from combustion
  • Capture systems after combustion (see Patent RU 2676642 Cl BOID 53/02, publ. 01/03/2019, Bull. 1, or Patent RU 2689620 Cl BOID 53/14, publ. 16) separate CO2 from flue gases formed in the air as a result of primary fuel combustion. These systems typically use a liquid solvent to capture a small fraction of the CO2 (typically 3-15% by volume) present in the flue gas stream, in which the main constituent is nitrogen (from the air).
  • the disadvantage of this method is that the concentration of carbon dioxide in the combustion products (flue gases) does not increase, and this saves the complexity of separating CO2 from nitrogen coming from the air during fuel oxidation. Capture is the most costly and most energy intensive step of the entire process.
  • Pre-combustion capture systems treat the primary fuel in a reactor with an air or oxygen saturated stream to create a mixture consisting primarily of carbon monoxide and hydrogen (“syngas”). Additional hydrogen along with CO2 is formed by the reaction of carbon monoxide with the stream in the secondary reactor. The resulting mixture of hydrogen and CO2 can then be separated into a CO2 gas stream and a hydrogen stream.
  • syngas carbon monoxide and hydrogen
  • SUBSTITUTE SHEETS (RULE 26) implementing the method, do not allow them to be widely used in transport.
  • the concentration of CO2 is not enough - in practice 15-60% by volume after drying the gases.
  • Oxygen-enriched combustion systems use oxygen instead of air to burn the primary fuel to produce flue gas, which consists mainly of water vapor and carbon dioxide. The water vapor is then removed by cooling and compressing the gas stream. A mixture of gases highly enriched in carbon dioxide remains.
  • Oxygen-enriched combustion systems are in the demonstration phase. Research is being carried out on the use of oxygen-enriched fuel systems in gas turbine systems, but the conceptual development of such applications is still at the research stage, since oxygen enrichment leads to an unacceptable increase in the temperature of the working processes.
  • the device of this type of heat engines contains an atmospheric air separator, an external combustion chamber in which oxygen of a high degree of purification (95-99%) is used, a mechanism for converting heat into mechanical energy, a device for separating carbon dioxide-enriched combustion products and its accumulation.
  • the exhaust gases of piston-type internal combustion engines contain 12-17% CO2, and gas turbine-type engines contain 3-5% carbon dioxide. Therefore, the separation of low concentration CO2 from this mass of air, for example, by cryogenic distillation, leads to excess energy consumption for cooling nitrogen and oxygen in the air to the temperature of CO2 condensation into a liquid. Other methods are also energy intensive due to the low concentration of carbon dioxide.
  • An attempt to solve this problem is a way to increase the concentration of CO2 by separating oxygen from the air and supplying it to the combustion chamber with a minimum amount of residual gases, which leads to a multiple increase in the proportion of CO2 in the combustion products.
  • a system in which, in order to lower the temperature around the combustion zone of fuel in oxygen and prevent the destruction of the combustion chamber,
  • the prototype implements a recuperable high-pressure Brayton cycle using a working fluid in the form of a supercritical fluid CO2 with a gas-oxygen fuel combustion mode.
  • This cycle begins with combustion in the combustion chamber of gaseous fuel with oxygen and a hot working fluid in the form of recycled supercritical CO2.
  • a hot working fluid in the form of recycled supercritical CO2.
  • Combustion in the presence of SCF-CO2 serves the dual purpose of lowering the temperature of the combustion flame to an acceptable level and diluting the combustion products so that the working fluid of the cycle is predominantly CO2.
  • the pressure in the combustion chamber can be up to about 30 MPa and the combustion feedstock is about 95% recycled CO2 by weight.
  • the combustor provides high pressure exhaust which can be fed into a turbo expander operating at a high pressure drop.
  • the exhaust mixture comes out of the expander in the form of subcritical CO2, mainly mixed with water obtained by combustion. This liquid enters the economizer heat exchanger, which cools the outlet
  • SUBSTITUTE SHEETS (RULE 26) expander to a temperature below 65 ° C against the flow of CO2, which is returned to the combustion chamber. After leaving the economizer heat exchanger, the expander exhaust is additionally cooled to a temperature close to ambient temperature using a central cooling system, which allows liquid water to be removed from the working fluid.
  • the remaining working body of almost pure CO2 then passes to the stage of compression and pumping.
  • the compression system consists of a conventional intercooled centrifugal compressor with an inlet pressure below the CO2 critical pressure.
  • the working fluid in the form of CO2 is compressed and then cooled to a temperature close to the ambient temperature in the aftercooler of the compressor.
  • the combination of compression and cooling of the working fluid makes it possible to achieve a density in excess of 500 kg/m 3 .
  • the CO2 stream can be pumped to the required high combustion pressure using a multi-stage centrifugal pump.
  • the high pressure working fluid is sent back through the economizer heat exchanger to be reheated and returned to the combustion chamber.
  • the pure CO2 product obtained by adding fuel and oxygen to the combustion chamber is removed from the high pressure stream; at this point CO2 is a high pressure, high purity product, ready to be sequestered or disposed of without the need for further compression.
  • the system provides a flow of combustion products containing CO2 at a pressure of at least about 8 MPa and a temperature of at least about 800 ° C, which, with high efficiency, solves the problem of eliminating losses in typical CO2 removal systems for its compression for injection into the pipeline, although it creates difficulties due to excessive pressure of the working fluid associated with high temperature.
  • the combustion chamber of the prototype is similar to rocket jet engines, which affects the working life, reliability and cost of its manufacture.
  • the combustion chamber like the turbine of the system, is therefore atypical, not standard - for the new system, Toshiba has designed a special turbine and a special combustion chamber, corresponding to the unique physical conditions.
  • the disadvantages include the fact that supercritical carbon dioxide is a very strong solvent. Due to the extreme temperatures and pressures under which it is used, very stringent requirements are placed on the materials of construction. It is reported that one of the most resistant alloys of titanium, nickel, chromium and aluminum, in contact with supercritical CO2 at a temperature of 750 ° C, thins by 1-2 microns per year). This means that such thermal power plants may encounter still unknown problems during operation (see Aleksey Batyr. Supercritical approach. Energy science.
