Description

carbon dioxide capture device

[0001] The present invention relates to a carbon dioxide capture device.

[0002] It is to be noted that the content described in this section merely provides background information for the present invention and does not constitute prior art.

[0003] In accordance with international maritime greenhouse gas emissions reduction targets, the amount of carbon dioxide emitted when transporting one ton of cargo one mile has been limited.

[0004] Ships are experimenting with a variety of methods to reduce carbon dioxide emissions, including improving energy efficiency, switching fuels, and developing onboard carbon dioxide capture technology.

[0005] Carbon dioxide (CO) for ships 2) In capture technology, reducing the size of the carbon dioxide capture device is very important because as the size of the capture process increases, the amount of cargo that can be shipped decreases.

[0006] Additionally, when a carbon dioxide capture device is installed on a moving vessel, the device may move due to the movement of the vessel. Consequently, the exhaust gas and liquid within the device may also move, reducing its carbon dioxide capture performance.

[0007] In particular, in an example where the carbon dioxide capture device is installed as a high-rise column type, liquid and gas flow inside the high-rise column according to the movement of the ship, so channeling occurs inside the high-rise column and the carbon dioxide capture performance is reduced.

[0008] For example, according to a study by Ros et al. (2022), when the high-rise column was tilted 5° from vertical (semi-tilted), the carbon dioxide capture rate decreased by 7% compared to when the high-rise column was not tilted (straight), and when the high-rise column was tilted 10° from vertical (full tilted), the carbon dioxide capture rate decreased by approximately 19% compared to when the high-rise column was not tilted (straight).

[0009] Therefore, there is a need to develop a carbon dioxide capture device that can reduce the size of the carbon dioxide capture device and overcome the decrease in carbon dioxide capture performance due to the movement of the ship, etc.

[0050] Hereinafter, the present invention will be described in detail through examples. However, it should be noted that the examples described below are intended only to illustrate and concretize the present invention and are not intended to limit the scope of the invention. This is because the scope of the invention is determined by the matters set forth in the patent claims and matters reasonably inferred therefrom.

[0051] Figure 1 is a drawing illustrating a carbon dioxide capture device (1) of a comparative example.

[0052] Referring to Fig. 1, the carbon dioxide capture device (1) of the comparative example may include a carbon dioxide capture device (1) that captures carbon dioxide contained in exhaust gas (G) and a stripping tower (2) that separates carbon dioxide from a liquid (L) that has moved from the carbon dioxide capture device (1).

[0053] However, the carbon dioxide capture device (1) of the comparative example has a problem in that the height is greatly increased compared to the carbon dioxide capture device (10) according to one embodiment of the present invention, and thus space cannot be utilized efficiently.

[0054] In order to overcome the shortcomings of the carbon dioxide capture device (1) of the comparative example, the carbon dioxide capture device (10) according to one embodiment of the present invention aims to reduce the size of the carbon dioxide capture device (10) to efficiently utilize space and improve the capture efficiency of carbon dioxide.

[0055] Hereinafter, components included in a carbon dioxide capture device (10) according to one embodiment of the present invention will be specifically described with reference to FIGS. 2 and 3.

[0056] Fig. 2 is a perspective view illustrating some components included in a carbon dioxide capture device (10) of a carbon dioxide capture device (10) according to one embodiment of the present invention. Fig. 3 is a cross-sectional view of a carbon dioxide capture device (10) of a carbon dioxide capture device (10) according to one embodiment of the present invention.

[0057] A carbon dioxide capture device (10) according to one embodiment of the present invention may include a chamber unit (100), a rotor unit (200), and a rotation unit (300).

[0058] The chamber unit (100) has a receiving space (130) provided inside, and exhaust gas (G) containing carbon dioxide and a liquid (L) reacting with the exhaust gas (G) can flow in and out.

[0059] Exhaust gas (G) can be supplied to the receiving space (130) through the gas inlet pipe (111). The exhaust gas (G) can move through the flow path structure (230) due to the supply pressure of the exhaust gas (G). Accordingly, when the liquid (L) and the exhaust gas (G) intersect in the multiple flow paths of the flow path structure (230), carbon dioxide contained in the exhaust gas (G) can be captured in the liquid (L).

[0060] The rotor unit (200) is installed rotatably in the receiving space (130) and may have a crossing space (210) where the liquid (L) and exhaust gas (G) intersect.

[0061] The liquid (L) and exhaust gas (G) intersect each other in the intersection space (210), so that the liquid (L) can capture carbon dioxide from the exhaust gas (G).

[0062] It can rotate around the rotation center axis (X) of the rotor unit (200). Centrifugal force is applied to the rotor unit (200), and centrifugal force can also be applied to the duct structure (230) of the rotor unit (200).

[0063] When the rotor unit (200) rotates, the liquid (L) can move to the outer circumferential side of the rotation center axis (X) through the flow path structure (230) by centrifugal force. The exhaust gas (G) can move to the inner circumferential side of the rotation center axis (X) through the flow path structure (230) by the supply pressure of the exhaust gas (G).

[0064] Accordingly, the liquid (L) and the exhaust gas (G) can intersect while moving in opposite directions in the flow path structure (230), and the carbon dioxide contained in the exhaust gas (G) can be captured and moved into the liquid (L).

[0065] Liquid (L) and exhaust gas (G) can each pass through the flow path structure (230). The liquid (L) can move in a direction away from the rotation center axis (X), and the exhaust gas (G) can move in a direction closer to the rotation center axis (X).

[0066] Liquid (L) and exhaust gas (G) come into contact with each other and react, and the liquid (L) can capture carbon dioxide contained in the exhaust gas (G). Since the liquid (L) and exhaust gas (G) come into contact with each other and react, the carbon dioxide capture efficiency can be improved when the contact area between the two is maximized.

[0067] The carbon dioxide capture performance may vary depending on the supply speed of exhaust gas (G) and liquid (L), the rotation speed of the rotor unit (200), etc.

[0068] The rotation unit (300) can drive the rotor unit (200) to rotate.

[0069] For example, the rotation unit (300) can rotate the rotor unit (200) placed inside the chamber unit (100) while being installed on one side of the chamber unit (100).

[0070] The rotor unit (200) may have a flow path structure (230) that forms multiple flow paths in a cross space (210). Liquid (L) and exhaust gas (G) may intersect each other while moving through the multiple flow paths.

[0071] The euro structure (230) is installed across the intersection space (210) and may be configured in a cylindrical ring shape. The euro structure (230) may be installed so as to fill the cylindrical ring-shaped space.

[0072] A multi-channel system can be a system with multiple channels through which liquid (L) and exhaust gas (G) move.

[0073] For example, a multi-channel may be formed by forming multiple channels between the pores of a channel structure (230) formed in a mesh pattern. As another example, a multi-channel may be formed by forming multiple channels through which a liquid (L) and exhaust gas (G) move between the spaced-apart channel pins (230-2) when multiple channel pins (230-2) are installed at a distance from each other. This will be described in more detail later.

[0074] For example, the carbon dioxide capture device (10) of the present invention can be installed on a ship.

[0075] The carbon dioxide capture device (10) of the present invention can improve the capture efficiency of carbon dioxide by maximizing the contact area between the liquid (L) and the exhaust gas (G) by forming multiple channels in the cross space (210) through the flow path structure (230).

[0076] The carbon dioxide capture device (10) of the present invention is configured to capture carbon dioxide while the rotor unit (200) rotates and the exhaust gas (G) and liquid (L) cross each other, thereby significantly increasing the material transfer speed and improving the carbon dioxide capture efficiency.

[0077] By reducing the size of the carbon dioxide capture device (10) of the present invention, there is an effect of efficiently utilizing space in a ship with limited space and improving the capture efficiency of carbon dioxide.

[0078] The euro structure (230) can be installed to occupy a ring-shaped space in the intersection space (210).

[0079] The liquid (L) can move from the inner first side (230-1a) of the flow path structure (230) toward the outer second side (230-1b) of the flow path structure (230) by the centrifugal force acting on the rotor unit (200). The exhaust gas (G) can move from the second side (230-1b) toward the first side (230-1a) by the supply pressure of the exhaust gas (G).

[0080] The exhaust gas (G) can escape the flow path structure (230) by passing through the first side (230-1a) and can move through the space below the liquid distribution chamber (170) described later. Thereafter, it can be discharged to the outside of the carbon dioxide capture device (10) through the gas discharge pipe (112).

[0081] The first side (230-1a) is the inner diameter side of the ring-shaped euro structure (230), and the second side (230-1b) is the outer diameter side of the ring-shaped euro structure (230).

[0082] When the rotor unit (200) rotates, a centrifugal force may be applied to the flow path structure (230). When the rotor unit (200) rotates, the liquid (L) may move outward in the circumferential direction through the flow path structure (230) due to the centrifugal force. Specifically, the liquid (L) may move toward the first side (230-1a) of the flow path structure (230). The liquid (L) may be introduced through the first side (230-1a) of the flow path structure (230), pass through the interior of the flow path structure (230), and be discharged through the second side (230-1b) of the flow path structure (230).

[0083] The chamber unit (100) may include a chamber body (110) and a liquid distribution chamber (170).

[0084] The chamber body (110) may have a receiving space (130) inside.

[0085] A gas inlet pipe (111), a gas discharge pipe (112), a liquid inlet pipe (113), and a liquid discharge pipe (114) can be installed in the chamber body (110).

[0086] The gas inlet pipe (111) can receive exhaust gas (G) containing carbon dioxide. The gas discharge pipe (112) can discharge the received exhaust gas (G) via the rotor unit (200). For example, the gas inlet pipe (111) can be arranged on one side of the chamber unit (100), and the gas discharge pipe (112) can be arranged on the upper side of the chamber unit (100).

[0087] The liquid inlet pipe (113) can receive liquid (L) that reacts with exhaust gas (G). The liquid discharge pipe (114) can discharge the received liquid (L) via the rotor unit (200). For example, the liquid inlet pipe (113) can be arranged on the upper side of the chamber unit (100), and the liquid discharge pipe (114) can be arranged on the lower side of the chamber unit (100).

[0088] The liquid distribution chamber (170) is fixed to the chamber body (110) and can distribute liquid (L) toward the flow path structure (230).

[0089] The liquid distribution chamber (170) can be placed in the receiving space (130), and the liquid distribution chamber (170) is a fixed component that does not rotate.

[0090] The liquid distribution chamber (170) is arranged around the first side (230-1a) of the flow path structure (230) and can distribute the liquid (L) toward the first side (230-1a) of the flow path structure (230).

[0091] A flow path structure (230) is arranged on the outside of the liquid distribution chamber (170) based on the rotation center axis (X), and the liquid (L) distributed from the liquid distribution chamber (170) can be discharged to the receiving space (130) on the outside of the flow path structure (230) via the flow path structure (230).

[0092] When the rotor unit (200) rotates, centrifugal force may be applied to the flow path structure (230) of the rotor unit (200). The discharged liquid (L) may be pulled by the centrifugal force applied to the flow path structure (230) and may move toward the flow path structure (230).

[0093] Liquid (L) discharged from the liquid distribution chamber (170) can move to the receiving space (130) of the chamber unit (100) through the flow path structure (230) installed in the cross space (210).

[0094] It can be placed apart from the inner surface of the chamber body (110) on the lower side of the liquid distribution chamber (170). The exhaust gas (G) can escape the flow path structure (230) while passing through the first side (230-1a) of the flow path structure (230). Thereafter, it can move to the gas discharge pipe (112) via the space on the lower side of the liquid distribution chamber (170) and be discharged to the outside of the carbon dioxide capture device (10).

[0095] The liquid distribution chamber (170) may include a cylindrical ring chamber (171) and a disassembly hole.

[0096] The cylindrical ring chamber (171) is configured in a cylindrical ring shape and is arranged around the inner diameter side first side (230-1a) of the flow path structure (230) to distribute liquid (L) toward the flow path structure (230).

[0097] The upper portion of the cylindrical ring chamber (171) can be connected to a liquid storage chamber (150). The cylindrical ring chamber (171) can receive liquid (L) at a constant pressure from the liquid storage chamber (150) described later.

[0098] The distribution hole (173) is formed penetrating the cylindrical ring chamber (171) and can form a path for distributing liquid (L) toward the first side (230-1a).

[0099] The distribution hole (173) can be arranged in the direction of the flow path structure (230). Liquid (L) can move from the cylindrical ring chamber (171) toward the flow path structure (230) through the distribution hole (173). When the flow path structure (230) has a cylindrical ring shape, a plurality of distribution holes (173) can be arranged spaced apart from each other along the circumferential direction and the height direction of the cylindrical ring shape.

[0100] The liquid (L) discharged from the distribution hole (173) can move toward the first side (230-1a) of the flow path structure (230) while being pulled by the centrifugal force acting on the flow path structure (230). Thereafter, the liquid (L) can be introduced through the first side (230-1a) of the flow path structure (230), pass through the interior of the flow path structure (230), and be discharged into the receiving space (130) of the chamber body (110) through the second side (230-1b) of the flow path structure (230).

[0101] The chamber unit (100) may further include a liquid storage chamber (150).

[0102] The liquid storage chamber (150) is arranged on one side of the chamber body (110) and can supply the stored liquid (L) to the liquid distribution chamber (170). The liquid storage chamber (150) stores the liquid (L) introduced through the liquid inlet pipe (113) and is connected to the liquid distribution chamber (170) to supply the liquid (L) to the liquid distribution chamber (170). The liquid storage chamber (150) can serve to supply the stored liquid (L) to the liquid distribution chamber (170) at a constant pressure.

[0103] The liquid storage chamber (150) is arranged above the liquid (L) distribution chamber, and the liquid storage chamber (150) can have a larger liquid (L) storage space than the liquid distribution chamber (170). Accordingly, the liquid (L) stored in the liquid storage chamber (150) can be supplied to the liquid distribution chamber (170) at a constant pressure.

[0104] For example, the liquid storage chamber (150) may be placed on the upper side of the chamber body (110), and the liquid storage chamber (150) may be placed to surround the gas discharge pipe (112).

[0105] Figure 4 is a drawing showing details of part 'A' of Figure 3.

[0106] Referring to FIG. 4, the euro structure (230) may include a mesh structure (230-1) formed in a network shape.

[0107] For example, the flow path structure (230) may be composed of a mesh structure (230-1). In the mesh structure (230-1), multiple flow paths may be formed in which liquid (L) and exhaust gas (G) intersect each other. Specifically, multiple flow paths may be formed in which exhaust gas (G) and liquid (L) move between the mesh structures of the mesh structure (230-1).

[0108] Referring to FIG. 4, the euro structure (230) may include an upper rotor plate (233), a lower rotor plate (235), and a mesh structure (230-1).

[0109] The upper rotor plate (233) is placed on the upper side of the intersection space (210) and can be installed to block the upper side of the intersection space (210).

[0110] A sealing member (S) may be placed between the chamber body (110) and the upper rotor plate (233). The sealing member (S) may prevent exhaust gas (G) from moving between the chamber body (110) and the upper rotor plate (233). The sealing member (S) may be configured in a ring shape.

[0111] For example, the sealing member (S) may be fixed to the chamber body (110), and the sealing member (S) may be separated from the rotor unit (200). That is, the upper rotor plate (233) of the rotor unit (200) is positioned in close proximity to the sealing member (S) to prevent movement of exhaust gas (G), and the rotor unit (200) may rotate in close proximity to the sealing member (S).

[0112] The lower rotor plate (235) can be spaced apart in the height direction from the upper rotor plate (233). The lower rotor plate (235) can be placed on the lower side of the intersection space (210) and installed to block the lower side of the intersection space (210).

[0113] The first drive shaft (310) of the rotation unit (300) can be fixed to the lower rotor plate (235), and when the first rotational driving member (330) rotates the first drive shaft (310), the lower rotor plate (235) fixed to the first drive shaft (310) rotates together, allowing the rotor unit (200) to rotate.

[0114] An intersection space (210) is arranged between the upper rotor plate (233) and the lower rotor plate (235), and a mesh structure (230-1) can be arranged in the intersection space (210).

[0115] The mesh structure (230-1) is installed between the upper rotor plate (233) and the lower rotor plate (235), and can be formed in a mesh shape and installed to occupy a ring-shaped space in the intersection space (210).

[0116]

[0117] The mesh structure (230-1) is formed in a mesh shape, so that exhaust gas (G) and liquid (L) can move through the mesh structure (230-1).

[0118] The mesh structure (230-1) can be installed so that the mesh structure fills a ring-shaped space.

[0119] For example, the mesh structure (230-1) may be blocked at the upper end by the upper rotor plate (233) and at the lower end by the lower rotor plate (235). Accordingly, the exhaust gas (G) and the liquid (L) may move into the interior of the mesh structure (230-1) or out of the mesh structure (230-1) through the first side (230-1a) and the second side (230-1b) of the mesh structure (230-1).

[0120] For example, a mesh structure (230-1) having a ring shape can be installed integrally in the intersection space (210).

[0121] The mesh structure (230-1) may be formed as an integral body in which a mesh structure is filled in a ring-shaped space. For example, the mesh structure (230-1) may be manufactured as an integral body in the shape of a cylindrical ring.

[0122] FIG. 5 is a drawing showing a part corresponding to part 'A' of FIG. 3 in a carbon dioxide capture device (10) according to another embodiment of the present invention.

[0123] Referring to Fig. 5, the mesh structure (230-1) can be filled in a ring-shaped space by winding a mesh ribbon (230-1c) formed in a mesh shape.

[0124] FIG. 6 is a drawing showing a part corresponding to part 'A' of FIG. 3 in a carbon dioxide capture device (10) according to another embodiment of the present invention.

[0125] The euro structure (230) comprises a plurality of euro pins (230-2) spaced apart from each other, and multiple passages can be formed between the plurality of euro pins (230-2). Multiple passages in which liquid (L) and exhaust gas (G) intersect can be formed between the plurality of euro pins (230-2).

[0126] The rotor unit (200) may include an upper rotor plate (233), a lower rotor plate (235), and a plurality of Euro pins (230-2).

[0127] The upper rotor plate (233) and the lower rotor plate (235) have been previously described with reference to FIG. 4, so to avoid duplication, the description will be omitted and the description will focus on the contents different from those described in FIG. 4.

[0128] The Euro pin (230-2) is fixed to at least one of the upper rotor plate (233) and the lower rotor plate (235), and a plurality of them can be arranged spaced apart from each other in the cross space (210).

[0129] The Euro pin (230-2) can be extended in the vertical direction. For example, the Euro pin (230-2) can be installed to connect the upper rotor plate (233) and the lower rotor plate (235). One end of the Euro pin (230-2) can be fixed to the upper rotor plate (233), and the other end of the Euro pin (230-2) can be fixed to the lower rotor plate (235). For example, the Euro pin (230-2) can be configured as a cylindrical pin whose length in the height direction is longer than its diameter.

[0130] As another example, the Euro pin (230-2) may have one end fixed to at least one of the upper rotor plate (233) and the lower rotor plate (235).

[0131] Fig. 7 is a perspective view of a carbon dioxide capture device (10) according to another embodiment of the present invention. Fig. 8 is a perspective view of a carbon dioxide capture device (10) according to another embodiment of the present invention.

[0132] Referring to FIGS. 7 and 8, the carbon dioxide capture device (10) may further include an elastic unit (400).

[0133] The elastic unit (400) is installed in the chamber unit (100) and can elastically support the chamber unit (100). For example, the elastic unit (400) may be configured as a spring member that supports the chamber unit (100). A plurality of spring members may be installed to support the lower side of the chamber unit (100).

[0134] A plurality of elastic units (400) may be installed along the lower edge of the chamber unit (100). For example, when the lower edge of the chamber unit (100) has a circular shape, a plurality of elastic units (400) may be arranged in a circular shape along the circular edge of the chamber unit (100).

[0135] When a flow occurs in a ship, etc., the elastic unit (400) elastically supports the carbon dioxide capture device (10) installed in the ship, etc. to minimize the flow, thereby preventing the carbon dioxide capture efficiency from decreasing.

[0136] Referring to FIG. 7, the rotation unit (300) may include a first drive shaft (310) and a first rotation drive member (330).

[0137] The first drive shaft (310) can be fixed to the rotor unit (200) and can rotate together with the rotor unit (200).

[0138] The first drive shaft (310) is fixed to the lower side of the rotor unit (200), and the first drive shaft (310) can be arranged on the same line as the rotation center axis (X) of the rotor unit (200).

[0139] A sealing member (S) may be placed between the first drive shaft (310) and the lower rotor plate (235).

[0140] For example, the sealing member (S) may be fixed to the lower rotor plate (235), and the sealing member (S) may be separated from the first drive shaft (310). That is, the lower rotor plate (235) of the rotor unit (200) is arranged in proximity to the sealing member (S) to prevent movement of exhaust gas (G), and the first drive shaft (310) may rotate in proximity to the sealing member (S).

[0141] The first rotary drive member (330) is installed on one side of the chamber unit (100) and can rotate the rotor unit (200) by rotating the first drive shaft (310).

[0142] Referring to FIG. 8, the rotation unit (300) may include a rack gear (350), a second rotation driving member (370), and a support shaft (390).

[0143] The rack gear (350) may be installed on one side of the rotor unit (200). The rack gear (350) may be installed along the lower edge of the rotor unit (200). For example, the rack gear (350) may be installed along the lower edge of the lower rotor plate (235) of the rotor unit (200), and when the lower rotor plate (235) has a circular shape, the rack gear (350) may be installed along the circular edge.

[0144] The second rotary drive member (370) can rotate the pinion gear (371) that is engaged with the rack gear (350).

[0145] The second rotary drive member (370) is installed on one side of the chamber unit (100), and the rotary motor (373) can rotate the second drive shaft (372) to rotate the rotor unit (200). A pinion gear (371) is installed on the second drive shaft (372) of the second rotary drive member (370) so that they can rotate together.

[0146] The support shaft (390) can rotatably support the rotor unit (200).

[0147] The support shaft (390) is fixed to the lower side of the rotor unit (200), and the support shaft (390) can be arranged on the same line as the rotation center axis (X) of the rotor unit (200).

[0148] The rotation center axis (X) of the rotor unit (200) can be formed to extend in the longitudinal direction. For example, the rotation center axis (X) can be installed vertically in the longitudinal direction.

[0149] When the installation space where the carbon dioxide capture device (10) is installed is a longitudinally long space, it may be advantageous in terms of efficient use of the installation space for the rotation center axis (X) of the rotor unit (200) to be extended in the longitudinal direction.

[0150] Fig. 9 is a perspective view of a carbon dioxide capture device (10) according to another embodiment of the present invention. Fig. 10 is a cross-sectional view of a carbon dioxide capture device (10) according to another embodiment of the present invention.

[0151] The rotation center axis (X) of the rotor unit (200) can be formed to extend in the transverse direction. For example, the rotation center axis (X) can be installed horizontally in the transverse direction.

[0152] When the installation space where the carbon dioxide capture device (10) is installed is a horizontally long space, it may be advantageous in terms of efficient use of the installation space for the rotation center axis (X) of the rotor unit (200) to be extended horizontally.

[0153] The gas inlet pipe (111) can receive exhaust gas (G) containing carbon dioxide. The gas discharge pipe (112) can discharge the received exhaust gas (G) via the rotor unit (200). For example, the gas inlet pipe (111) can be arranged on one side of the chamber unit (100), and the gas discharge pipe (112) can be arranged on the other side of the chamber unit (100).

[0154] The liquid inlet pipe (113) can receive liquid (L) that reacts with exhaust gas (G). The liquid discharge pipe (114) can discharge the received liquid (L) via the rotor unit (200). For example, the liquid inlet pipe (113) can be arranged on the other side of the chamber unit (100), and the liquid discharge pipe (114) can be arranged on the lower side of the chamber unit (100).

[0155] Hereinafter, with reference to FIGS. 11 and 12, the carbon dioxide capture device (10) of the comparative example will be described in more detail in comparison with the carbon dioxide capture device (10) according to one embodiment of the present invention.

[0156] Fig. 11 is a perspective view illustrating a vessel having installed a carbon dioxide capture device (1, hereinafter referred to as “comparative example”) of the comparative example of Fig. 1. Fig. 12 is a perspective view illustrating a vessel (T) having installed a carbon dioxide capture device (10, hereinafter referred to as “the present invention”) according to an embodiment of the present invention.

[0157] Table 1 below shows information on gases emitted from a vessel with an output of 3,000 kW.

[0158] Ship information, exhaust gas information, classification, characteristics, flow rate, 13,139 m 3 / hFuelLNGN274.0 vol.%Engine power3,000 kWCO24.8 vol.%Vessel typeCargo shipO29.9 vol.%Deadweight tonnage8,000 tonsH2O10.4 vol.%Operating speed13 knotsAr0.9 vol.%

[0159] Since a ship (T, cargo ship) emits exhaust gas only when in operation, the actual exhaust gas (G) emitted when the ship (T) is in operation is approximately 10 to 25% of the theoretical total flow rate. However, the calculation was made based on the maximum emission of the ship (based on 100% load). When the carbon dioxide capture and removal rate of the cargo ship was set at 90%, the carbon dioxide capture amount was approximately 25.3 TPD (tons / day). Table 2 below shows the results comparing the comparative example and the present invention in a ship with an output of 3,000 kW.

[0160] Classification Comparison Example The present invention The amount of reduction in height and diameter of the present invention The volume reduction rate of the present invention Carbon dioxide capture device Height (H) 10 m2.7 m7.3 m73.0% Diameter (D) 1.5 m1.5 m0 Gas outlet - 0.3 m - Stripping tower height (H) 14 m2.9 m11.1 m64.1% Diameter (D) 0.76 m1.0 m - 0.24 m Gas outlet 0.3 m -

[0161] Here, the diameter of the carbon dioxide capture device (10) of the present invention of 1.5 m is a value including a gas outlet of 0.3 m, and the actual diameter of the carbon dioxide capture device (10) was 1.2 m. The diameter of the stripping tower (20) of the present invention of 1.0 m is a value including a gas outlet of 0.3 m, and the actual diameter of the carbon dioxide capture device (10) was 0.7 m. Compared to the comparative example of the present invention, the volume of the carbon dioxide capture device was reduced by about 73.0%, and compared to the comparative example of the present invention, the stripping tower was reduced by 64.1%.

[0162] In this way, it was found that the present invention occupies a much smaller space than the comparative example, and thus can efficiently utilize space in limited spaces such as ships.

[0163] Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and it will be apparent to those skilled in the art that various modifications and variations are possible within a scope that does not depart from the technical spirit of the present invention described in the claims.
