TECHNICAL FIELD [0001] The present invention relates to a carbon dioxide capture reactor, a carbon dioxide capture apparatus, and a carbon dioxide capture method using the same.

One embodiment of the present invention relates to a carbon dioxide capture reactor, a carbon dioxide capture device, and a carbon dioxide capture method using the same.

Technological measures to reduce carbon dioxide (CO ₂ ) to cope with climate change include improving energy efficiency, using renewable energy and nuclear energy, and capturing and storing carbon dioxide. Carbon dioxide capture and storage technologies are collectively referred to as CCS (carbon capture and storage), which collects, separates, compresses, and transports and safely stores carbon dioxide generated by the use of fossil fuels before discharging it to the atmosphere. Such a CCS technology will contribute to the achievement of domestic and overseas GHG reduction targets as the only technology that can reduce 20% (2050 standard) of global CO2 emissions by applying to the industries such as thermal power generation, steel, oil and cement. Such a CCS technology is particularly effective when applied to the coal-fired power generation industry, and it is becoming more important because it will contribute to the nation's energy security, economic development and public health, as well as achieving the national GHG reduction target .

Carbon dioxide capture technology is a core technology that accounts for more than 75% of the total cost of CCS technology, including pre-combustion technology, post-combustion technology and oxy-fuel combustion technology ).

Among the carbon dioxide capture techniques, the post-combustion capture technique captures the carbon dioxide contained in the exhaust gas generated after the combustion process. The post-combustion capture technology can operate at low temperature under atmospheric pressure and has the advantage of being relatively close to commercialization. However, it is necessary to solve the problem of excessive energy cost and it is necessary to solve the problem of impurities such as dust, SOx and NOx There is a drawback that it must be removed.

Various technologies such as wet absorption, dry absorption, adsorption, PSA (pressure swing adsorption), membrane separation, and seawater cooling are under development in this kind of technology. Research direction of current post combustion combustion technology is development of absorbent for lowering CO2 capture unit price And the development of low-cost capture technology through simplification of the process.

The present post-combustion dry carbon dioxide capture technology currently being developed in Korea uses a solid absorbent that selectively reacts with carbon dioxide selectively in the absorption reactor to collect carbon dioxide, recover the carbon dioxide by regenerating the carbon dioxide to the regeneration reactor to separate the carbon dioxide, The absorbent is circulated again, and the above process is repeated to collect carbon dioxide.

Research and development on carbon dioxide capture process using fluidized bed or mobile bed has been under way for industries such as power plants, cement, refinery chemical plants, steel mills, etc., which mainly produce carbon dioxide in Korea and USA.

However, conventional dry CO2 capture processes have relatively many advantages over wet processes, but have problems to overcome such as low CO2 capture rate and complicated devices. In addition, in order to be applied to the fluidized bed process, it is necessary to manufacture a spherical absorbent having a high wear resistance higher than a certain strength (AI value, Attrition Index), and to overcome the development of a mass production technology of an absorbent using a spray- can see.

1, a carbon dioxide capture reactor 100 according to an embodiment of the present invention includes a housing 100a, an exhaust gas inlet 101, a dispersion plate 102, a cooling unit 103, a mesh plate A condenser water outlet 111 and an absorbent inlet unit 106. The filter 105 and the exhaust gas outlet 106 are connected to an exhaust gas outlet valve 107, a carbon dioxide outlet valve 108, a water condenser 109, a carbon dioxide outlet 110, 112) and an absorbent discharge unit (113).

The exhaust gas inlet (101) is formed at the lower end of the housing (100a). Here, exhaust gas is injected into the reactor 100 through the exhaust gas inlet 101, and steam is injected into the reactor 100 during a regeneration reaction.

The dispersion plate 102 is formed on the lower surface of the housing 100a and injects the steam or steam injected through the steam inlet 101 into the upper portion of the housing 100a. At this time, the injection rate is injected at the rate of bubbling, sludging, and turbulence, and serves to promote the absorption or regeneration reaction by turbulating and bubbling the absorbent.

The cooling unit 103 is located inside the housing 100a and is installed to a lower portion of the absorbent turbulence region or an intermediate portion of the exhaust gas discharge region. When the alkali metal-based absorbent is used, the cooling unit 103 cools the temperature rise of the reactor due to the exothermic reaction occurring in the absorption reaction of the absorbent such as the following Chemical Formula 3 and Chemical Formula 4 to a temperature suitable for the absorption reaction It plays a role.

(3)

[Chemical Formula 4]

Here, in the case of a solid amine absorbent (30% MEA), an absorption reaction similar to that of the general formula (5) occurs and a relatively low exothermic reaction occurs compared with the alkali absorbent.

The cooling unit 103 can cool the reactor by the exothermic reaction of the formulas (3) to (5) by a water-cooling type, an air-cooling type or a gas cooling type, but the present invention is not limited thereto. As described above, the cooling unit 103 can cool the temperature in the reactor to the reaction temperature of the absorbent to improve the carbon dioxide capture ratio.

In addition, the cooling unit 103 is also used in the cooling operation mode of the absorbent after the absorbent regeneration reaction.

The mesh plate 104 is attached to the upper surface of the housing 100a and designed to prevent the scattering of the absorbent that may occur during the absorption reaction and the regeneration reaction. For example, if the minimum size of the absorbent is 50 탆, a plate of about 270 mesh or less can be provided.

The filter 105 is formed at the upper end of the housing 100a and serves to remove the fine absorbent powder scattered through the mesh plate 104 in the exhaust gas before the exhaust gas is discharged to the exhaust gas outlet 106. [

The exhaust gas outlet 106 is formed at the upper end of the reactor 100, and the exhaust gas from which the carbon dioxide in the exhaust gas is removed during the absorption reaction is discharged. In the carbon dioxide absorption reaction process, the exhaust gas discharge valve 107 is opened and the carbon dioxide discharge valve 108 is closed.

The water condenser 109 is formed on the upper part of the reactor 100 to condense the steam used during the regeneration reaction and the moisture generated during the regeneration reaction to remove moisture to separate the high purity carbon dioxide. In the carbon dioxide regeneration process, the flue gas discharge valve 107 is closed and the carbon dioxide discharge valve 108 is opened.

The carbon dioxide outlet 110 is formed on the water condenser 109 to discharge high-purity carbon dioxide from which water has been removed from the water condenser.

The condensed water outlet 111 is formed below the water condenser 109 and serves to discharge moisture removed from the condenser 109 through a condensate discharge valve 111a.

The absorbent injection unit 112 is formed on the left side or the upper right side of the housing 100a and is provided with a slide gate or a control valve to adjust the absorbent injection amount and absorbent replenishment amount necessary for the absorption reaction.

The absorbent discharge unit 113 is connected to one side of the flue gas inlet 101 at a lower portion of the reactor 100 and has a slide gate or a control valve to collect a sample for absorbent discharge and analysis .

A process of collecting carbon dioxide in a carbon dioxide capture reactor having the above-described configuration and a series of processes for regenerating carbon dioxide will be described with reference to FIG.

2 is a flowchart illustrating a carbon dioxide capture method according to an embodiment of the present invention.

The carbon dioxide capture method according to an embodiment of the present invention includes an absorption reaction (S1), a regeneration reaction (S2), a cooling reaction (S3), and a standby state (S4).

First, in the absorption reaction (S1), the reactor 100 is filled with a certain amount of the dry carbon dioxide absorbent, and when the flue gas containing carbon dioxide is injected at the turbulent flow rate through the dispersing plate 102 through the flue gas inlet 101, Absorbs the carbon dioxide in the exhaust gas as shown in [Formula 3] to [Formula 5] while being turbulent in the entire region of the reactor. At this time, in order to control the exothermic reaction in the absorption reaction, a cooling medium flows in the cooling unit 103 to cool the inside of the collection reactor 100.

Thereafter, the exhaust gas from which the carbon dioxide has been removed is discharged through the exhaust gas outlet 106 after the fine dispersing agent is removed from the filter 105. In this absorption process, the carbon dioxide discharge valve 108 is closed.

Usually because during the off-gas the concentration of water (H ₂ O) of about 10%, the concentration of the carbon dioxide 12 ~ 14%, the old K series (K ₂ CO ₃₎ Water (H that supplies further the process of using a sorbent ₂ O) at a temperature (70 degrees) at which the absorbent does not aggregate. At this time, water (H ₂ O) in the flue gas acts as a very important parameter in this reaction mechanism. That is, since the carbon dioxide absorbent is equivalent to the equivalent amount of the reaction mechanism, theoretically the carbon dioxide removal rate can not be 100% when there is no humidity control step for supplying additional water. However, in the application method proposed in the present invention, Instead, the absorption temperature is 60? And it is possible to expect a certain level of carbon dioxide removal rate improvement by increasing the contact area and the contact time through the turbulence. As a result, it is possible to omit the process of supplementing water to increase the carbon dioxide removal rate as in the high-speed fluidized bed process to be applied to the existing large-scale plant. However, if necessary, a moisture conditioning process for supplying moisture may be added to the portion of the exhaust gas inlet 101 to increase the removal rate of carbon dioxide. In addition, additional facilities such as mechanical, electric, and control valves can be added to smoothly operate the device.

Thereafter, in the regeneration reaction (S2), when the absorption reaction is completed in the reactor (100), the regeneration mode is switched to inject the steam through the exhaust gas inlet (101) Is bubbled in the reactor to cause a regeneration reaction such as the following formulas (6) to (8) to separate the absorbent and carbon dioxide. Here, the carbon dioxide separated from the steam recovered from the absorbent is condensed into condensed water in the water condenser 109 after the fine dispersing agent is removed from the filter 105, and then discharged through the condensate water outlet 111 And the high-purity carbon dioxide is discharged through the carbon dioxide exhaust port 110. [ The high-purity carbon dioxide emitted can be either stored for recycling or transported directly to the user. In this regeneration step, the exhaust gas discharge valve 107 is closed.

[Chemical Formula 6]

[Chemical Formula 8]

Carbon dioxide absorbent is potassium carbonate (K ₂ CO-) of the active substance and sodium carbonate (Na ₂ CO ₃₎ water in the exhaust gas (H ₂ O) and carbon dioxide (CO _2), and potassium carbonate to reaction (KHCO ₃₎ or Sodium hydrogen carbonate (NaHCO ₃ ). Theoretically, the lower the reaction temperature, the more favorable the carbon dioxide absorption reaction. Compared with these two absorbents, the reaction temperature of sodium carbonate is low and the absorption ability of carbon dioxide is high, which is economical. In the case of solid amine sorbents, the reaction heat may be lower, which may have the advantage of reducing the renewable energy. However, in the case of the calcium carbonate (K ₂ CO ₃ ) absorbent, it is possible to utilize that the sesquihydrate (K ₂ CO ₃ 1.5H ₂ O) generated in the regeneration process of the direct heating method using steam, , The existing absorbent technology can greatly reduce the renewable energy.

In the cooling reaction (S3), when the regeneration is completed in the reactor (100), the cooling medium is injected through the cooling unit (103) and the absorbent is cooled to a temperature of 60 deg. At this time, in order to increase the cooling efficiency, it is possible to add a process of bubbling by injecting and injecting high purity nitrogen or the like through the exhaust gas inlet 101.

Thereafter, when the cooling is completed, the reactor 100 enters the standby state S4.

As described above, continuous operation of the carbon dioxide capture reactor is possible by repeating the operation mode switching process in one reactor (100).

Also, in the present invention, as shown in FIGS. 3 to 4, the carbon dioxide capture reactors are bundled to form a carbon dioxide capture device.

FIG. 3 shows a carbon dioxide collecting apparatus 200 formed by arranging one row of reactors 201, 202, 203 and 204 when there is a space of a space for installation. FIG. 213, and 214, respectively, of the carbon dioxide collecting device 210 shown in FIG. In addition, although not shown, when the carbon dioxide treatment capacity is large, the capacity can be increased by providing two or more such arrangements upward.

FIG. 5 shows the sequence of reactions in the carbon dioxide capture reactors 201, 202, 203, 204 of FIG.

 Referring to FIG. 5, each of the carbon dioxide capture reactors 201, 202, 203, and 204 performs a series of reactions that are changed into an absorption reaction-> regeneration reaction-> cooling reaction-> standby state as described above. Of course, the absorption reaction is performed again after the atmospheric state to repeat a series of reactions.

More specifically, when the absorption reaction is performed in the first carbon dioxide capture reactor 201, a regeneration reaction is performed in the second carbon dioxide capture reactor 202, and a cooling reaction is performed in the third carbon dioxide capture reactor 203 And the fourth carbon dioxide capture reactor 204 performs a standby state.

When the regeneration reaction is carried out after completion of the absorption reaction in the first carbon dioxide capture reactor 201, the second carbon dioxide capture reactor 202 performs a cooling reaction and the third carbon dioxide capture reactor 203 And the fourth carbon dioxide capture reactor 204 performs an absorption reaction.

When the cooling reaction is completed after the regeneration reaction is completed in the first carbon dioxide capture reactor 201, the second carbon dioxide capture reactor 202 performs a standby state, and the third carbon dioxide capture reactor 203 absorbs And the fourth carbon dioxide capture reactor 204 performs a regeneration reaction.

In addition, when the first carbon dioxide capture reactor 201 performs a standby state after completion of the cooling reaction, the second carbon dioxide capture reactor 202 performs an absorption reaction, and in the third carbon dioxide capture reactor 203, And the fourth carbon dioxide capture reactor 204 performs a cooling reaction.

Here, such a sequential role of each reactor can be determined by taking time or absorbing amount of carbon dioxide (time) of the absorbent as a variable.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents. will be.
