[0003] Modular CO2 adsorption device for separating CO2 from a supplied air stream by means of an adsorption-desorption process

[0004] State of the art

[0005] The invention relates to an adsorption chamber module for a modular CO2 adsorption device, an adsorption fan module for a modular CO2 adsorption device, and a modular CO2 adsorption device for separating CO2 (carbon dioxide) from a supplied air stream by means of an adsorption-desorption process. The invention further relates to the use of an adsorption chamber module and / or an adsorption fan module and / or a modular CO2 adsorption device for separating CO2 from a supplied air stream, as well as to a method for producing an adsorption chamber module and a method for transporting a modular CO2 adsorption device.

[0006] WO 2020 / 212146 A1 discloses a DAC (Direct Air Capture) system with a cargo container, in which all essential technical components are arranged within the cargo container to comply with the external dimensions of the ISO 668 standard for cargo containers. While arranging the technical components within the main dimensions of ISO 668 allows for easy transport, it significantly reduces the available space for the adsorption-desorption chamber, i.e., the "reaction space" for the adsorption-desorption process. Furthermore, in the event of technical malfunctions, the entire complex cargo container must be repaired. Different sizes can only be accommodated by redesign.

[0007] Disclosure of the invention The subject of the present invention is an adsorption chamber module for a modular CO2 adsorption device for separating CO2 from a supplied air stream by means of an adsorption-desorption process, with

[0008] - a freight container acting as a chamber module housing, which is designed in particular according to ISO 668,

[0009] - an adsorption-desorption chamber arranged in the freight container for accommodating an adsorbent for adsorbing the CO2 from the supplied air stream,

[0010] - an inlet channel for supplying the air flow into the adsorption-desorption chamber, and

[0011] - an outlet duct for discharging the CO2-reduced air flow from the adsorption-desorption chamber, wherein the freight container has a receiving unit for releasably fastening at least one adsorption fan module of the modular CO2 adsorption device to an outer side of a freight container outer wall in order to guide the air flow by means of a fan unit of the adsorption fan module via the inlet duct into the adsorption-desorption chamber.

[0012] The present invention further relates to an adsorption fan module for a modular CO2 adsorption device for separating CO2 from a supplied air stream by means of an adsorption-desorption process, with

[0013] - a fan module housing, and

[0014] - a fan unit arranged in the fan module housing for supplying the air flow into an adsorption-desorption chamber for receiving an adsorbent for adsorbing the CO2 from the supplied air flow, wherein the adsorption-desorption chamber is arranged in a freight container, in particular according to ISO 668, of an adsorption chamber module of the modular CO2 adsorption device, wherein the fan module housing has an engagement unit for releasably fastening the adsorption fan module to an outer side of a freight container outer wall of the freight container in order to guide the air flow by means of the fan unit via an inlet channel of the adsorption chamber module into the adsorption-desorption chamber.The present invention also relates to a modular CO2 adsorption device for separating CO2 from a supplied air stream by means of an adsorption-desorption process, comprising a previously described adsorption chamber module and at least one previously described adsorption fan module.

[0015] The present invention further relates to a use of a previously described adsorption chamber module and / or a previously described adsorption fan module and / or a previously described modular CO2 adsorption device for separating CO2 from a supplied air stream.

[0016] The present invention also relates to a method for producing an adsorption chamber module for a modular CO2 adsorption device for separating CO2 from a supplied air stream by means of an adsorption-desorption process, in particular of the type described above, comprising the steps:

[0017] - Providing a freight container, which is designed in particular according to ISO 668, as a chamber module housing,

[0018] - Forming an adsorption-desorption chamber in the freight container to accommodate an adsorbent for adsorbing the CO2 from the supplied air stream,

[0019] - Forming an inlet channel for supplying the air flow into the adsorption-desorption chamber,

[0020] - Forming an outlet channel for discharging the CO2-reduced air flow from the adsorption-desorption chamber, and

[0021] - Forming a receiving unit on the freight container for releasably fastening at least one adsorption fan module of the modular CO2 adsorption device to an outer side of a freight container outer wall in order to guide the air flow by means of a fan unit of the adsorption fan module via the inlet channel into the adsorption-desorption chamber.

[0022] The present invention further relates to a method for

[0023] Transporting a previously described modular CO2

[0024] Adsorption device for separating CO2 from a supplied air stream by means of an adsorption-desorption process, wherein the at least one adsorption fan module is arranged in the adsorption-desorption chamber for transport purposes, so that the external dimensions of the freight container of the adsorption chamber module remain unchanged during transport.

[0025] The modular CO2 adsorption device according to the invention offers the significant advantage of maximizing the size and volume of the adsorption-desorption chamber, i.e., the separation into an adsorption chamber module and an adsorption fan module, which is crucial for the amount of adsorbable CO2 from the supplied air flow per container volume. This allows the external dimensions of the freight container (e.g., according to ISO 668) to be maintained for transport, and at the same time, by "separating" the voluminous fan unit into a separate adsorption fan module - which can be removably attached to the outside of the freight container's outer wall only on site (outside the main dimensions of ISO 668) - a much larger volume of the freight container can be used as an adsorption-desorption chamber for the adsorbent material to be cycled.Thus, the specific investment [EUR_adsorber technology / kg_adsorber material] can be significantly reduced.

[0026] Furthermore, the manufacturing process can be significantly reduced by separating the two components into a simple container steel structure and a mass-production technology. Furthermore, in the event of a technical malfunction, only the adsorption fan module needs to be repaired or replaced. Flexibility for different freight container sizes is also increased, as the adsorption fan modules can be manufactured in different sizes and / or performance classes, while the receiving unit and the intervention unit can remain unchanged.

[0027] In the context of the present invention, the term "separation" encompasses a separation, e.g., the capture of CO2 (carbon dioxide) from the air. In the context of the present invention, the term "supply" or "supplied" encompasses an actively performed or initiated, and thus technically controlled or regulated, supply of the air flow by means of a fan unit.

[0028] The modular CO2 adsorption device according to the invention is designed or configured to separate CO2 from a supplied air stream by means of an adsorption-desorption process, i.e., a cyclically performed or implemented adsorption-desorption process. The basic functionality of the modular CO2 adsorption device or of the cyclically performed or implemented adsorption-desorption process can be implemented, for example, analogously to WO 2015 / 185434 A1. For this purpose, the modular CO2 adsorption device comprises an adsorption chamber module according to the invention and at least one adsorption fan module according to the invention.

[0029] The adsorption chamber module is designed or configured to separate CO2 from a supplied air stream in a modular CO2 adsorption device by means of an adsorption-desorption process.

[0030] For this purpose, the adsorption chamber module has a freight container that acts as the chamber module housing. Freight containers are also known as ISO containers. The freight container is preferably designed as an ISO container according to ISO 668.

[0031] The freight container can preferably have a grid dimension of less than or equal to 8" width, since small 8" units, which are used, for example, in the form of building integration, i.e. for removing CO2 from room air when the container is installed in the area of ​​building air conditioning, can easily be combined to form 40" and / or 48" containers with several units for free-standing installation for greater separation capacities.

[0032] An adsorption-desorption chamber is arranged or configured within the freight container, i.e., within the external dimensions of the freight container. The adsorption-desorption chamber is designed or configured to accommodate an adsorbent for adsorbing the CO2 from the supplied air stream. A (suitably functionalized) adsorbent for adsorption, i.e., for binding or filtering the CO2 from the supplied air stream, e.g., in the form of CO2 adsorption modules, can be arranged in the adsorption-desorption chamber.

[0033] The adsorption chamber module further comprises an inlet channel for supplying the air flow into the adsorption-desorption chamber and an outlet channel for discharging the CO2-reduced air flow from the adsorption-desorption chamber. The inlet channel and the outlet channel are arranged in the cargo container, i.e., within the external dimensions of the cargo container.

[0034] The freight container has a receiving unit. The receiving unit is designed such that at least one adsorption fan module of the modular CO2 adsorption device can be releasably fastened to an outer side of a freight container outer wall in order to guide the air flow by means of a fan unit of the adsorption fan module via the inlet channel into the adsorption-desorption chamber. The freight container outer wall is preferably a lateral, i.e., transverse / frontal or longitudinal, freight container outer wall.

[0035] Accordingly, the receiving unit can be arranged on at least one transverse side or transverse-side freight container outer wall of the freight container and / or at least one longitudinal side or longitudinal-side freight container outer wall of the freight container, so that the at least one adsorption fan module can be releasably fastened to the respective side. However, the receiving unit can also be arranged on an upper freight container outer wall, to which the adsorption fan module can be releasably fastened such that it is arranged on the transverse side or longitudinal side.

[0036] Advantageously, the receiving unit is designed to form a detachable, positive connection with the at least one adsorption fan module, in particular an engagement unit of the at least one adsorption fan module. It is further advantageous if the receiving unit has at least one load-bearing area on the outside of the freight container outer wall, on and / or on which the at least one adsorption fan module can be suspended and / or placed and / or fixed for detachable fastening.

The terms "top" and "bottom" refer to the intended positioning and orientation of the cargo container.

[0037] Furthermore, it is advantageous if the receiving unit has at least one bearing element for the movable, in particular rotatable and / or pivotable and / or slidable mounting of the at least one adsorption fan module on the outside of the freight container outer wall. For this purpose, the receiving unit can, for example, have a hinge and / or a joint and / or a rail, or parts thereof.

[0038] It is further advantageous if the adsorption-desorption chamber is designed to at least partially, in particular completely, accommodate the at least one adsorption fan module for transport purposes, so that the external dimensions of the freight container remain unchanged during transport. It is advantageous if the adsorption-desorption chamber has a correspondingly dimensioned, in particular closable, opening through which the at least one adsorption fan module can be inserted into the adsorption-desorption chamber and removed again. This means thatIn other words, the adsorption-desorption chamber is preferably dimensioned so that the adsorption fan module can be arranged therein and the adsorption fan module can optionally also be transported within the dimensions of the freight container, so that the standard dimensions of the freight container remain unchanged during transport and the adsorption fan module can only be releasably attached to the outside of the freight container outer wall at the installation site.

[0039] Advantageously, the adsorption chamber module also has at least one fluidic connection for the fluidic connection of the at least one detachably attachable or attached adsorption fan module. In this case, by means of the fluidic connection, in particular a fan unit of the at least one adsorption fan module can be or are connected to the inlet channel of the adsorption chamber module and / or a temperature control unit of the at least one adsorption fan module can be or are connected to a temperature control line of the adsorption chamber module and / or a pump unit of the at least one adsorption fan module can be or are connected to a pressure connection of the adsorption chamber module for the desorption process. The at least one fluidic connection is preferably arranged in the freight container, i.e., within the external dimensions of the freight container.

[0040] In other words, the adsorption chamber module preferably has a temperature control line for controlling the temperature of the adsorbent for the adsorption-desorption process, with a corresponding fluidic connection, wherein the fluidic connection is fluidically connectable or connected to the at least one detachably attachable or attached adsorption fan module. Alternatively or additionally, the adsorption chamber module preferably has a pressure connection for providing an overpressure and / or negative pressure for the desorption process, wherein the fluidic connection is fluidically connectable or connected to the at least one detachably attachable or attached adsorption fan module.

[0041] The adsorption chamber module can also have at least one of the following units, which are arranged in the freight container, i.e. within the external dimensions of the freight container: Temperature control unit for temperature control of the adsorbent for the adsorption-desorption process by means of the temperature control line; Pump unit for providing the overpressure and / or negative pressure for the desorption process at the pressure connection; Closing unit for opening and / or closing the inlet channel and / or the outlet channel; Drive unit for components to be moved, in particular closing elements of the closing unit; Sensor unit for the adsorption-desorption process; Control unit for controlling and / or regulating the adsorption-desorption process; Energy supply unit and / or energy generation unit for the adsorption-desorption process.

[0042] It should be noted that the adsorption chamber module preferably does not have a fan unit for supplying the air flow into the adsorption-desorption chamber.

[0043] Advantageously, the adsorption chamber module further comprises at least one electrical connection, in particular an electrical plug connection for the electrical connection of the at least one detachably attachable or attached adsorption fan module.

[0044] In a further development, the adsorption chamber module for desorbing has a pumping device for providing the negative pressure, as well as an electrical connection for electrically heating the adsorber material.

[0045] The adsorption fan module is designed or configured to supply CO2 in a modular CO2 adsorption device with an air flow for the adsorption-desorption process.

[0046] For this purpose, the adsorption fan module comprises a valve housing and a fan unit. The fan unit is designed or configured to guide the air flow into an adsorption-desorption chamber for accommodating an adsorbent for adsorbing the CO2. The adsorption-desorption chamber is arranged in a freight container of an adsorption chamber module of the modular CO2 adsorption device.

[0047] The fan unit is arranged in the fan module housing. The fan unit does not have to be arranged completely in, i.e. within the dimensions of the fan module housing. The fan unit can have one or more fans. The fan module housing has an engagement unit. The engagement unit is designed to releasably fasten the adsorption fan module to an outer side of a freight container outer wall of the freight container in order to guide the air flow by means of the fan unit via an inlet channel of the adsorption chamber module into the adsorption-desorption chamber. Advantageously, the engagement unit is designed to enter into a releasable, positive-locking connection with the adsorption chamber module, in particular a receiving unit of the adsorption chamber module.

[0048] It is further advantageous if the engagement unit is designed for releasable fastening, to be suspended, placed, and / or fixed on the outside of the freight container outer wall in at least one load-bearing area. In other words, the engagement unit is preferably designed to be suspended, placed, and / or fixed on a correspondingly designed load-bearing area on the outside of the freight container outer wall.

[0049] In this case, the engagement unit is advantageously designed for detachable fastening, to be placed on at least one lower load-bearing point, in particular two lower load-bearing points of the load-bearing area, and / or to be fixed to at least one upper load-bearing point, in particular two upper load-bearing points of the load-bearing area.

[0050] Furthermore, it is advantageous if the engagement unit comprises at least one bearing element for movable, in particular rotatable and / or pivotable and / or sliding mounting on the outside of the freight container's outer wall. For this purpose, the engagement unit can comprise, for example, a hinge and / or a joint and / or a guide element, or parts thereof.

[0051] Advantageously, the fan unit further comprises at least one of the following units, which is / are arranged in and / or on the fan module housing: temperature control unit for temperature control of the adsorbent for the adsorption-desorption process; pump unit for providing an overpressure and / or underpressure for the desorption process; closing unit for opening and / or closing the inlet channel and / or the outlet channel; drive unit for components to be moved, in particular closing elements of a / the closing unit; sensor unit for the adsorption-desorption process; control unit for controlling and / or regulating the adsorption-desorption process; energy supply unit and / or energy generation unit for the adsorption-desorption process.

[0052] The adsorption fan module preferably has at least one fluidic connection for fluidic connection to the adsorption chamber module. In this case, the fluidic connection can be used to fluidically connect, in particular, the fan unit to the inlet channel of the adsorption chamber module, and / or the temperature control unit to a temperature control line of the adsorption chamber module, and / or the pump unit to a pressure connection of the adsorption chamber module for the desorption process.

[0053] The temperature control unit may include a heat pump and / or an electric heater

[0054] The closing unit is designed to open and / or close the inlet channel and / or the outlet channel and thus the adsorption-desorption chamber depending on the process. The closing unit can comprise one or more valves. The closing unit can have an inlet valve arranged in the inlet channel for the drawn-in air flow and designed to open and / or close the inlet channel and thereby isolate the adsorption-desorption chamber upstream. The closing unit can further have an outlet valve arranged in the outlet channel for the CO2-reduced air flow and designed to open and / or close the outlet channel and isolate the adsorption-desorption chamber downstream.The closing unit can also have a CO2 valve, which is arranged in a CO2 outlet channel of the adsorption-desorption chamber and is designed to open and / or close a CO2 outlet channel in order to specifically discharge the adsorbed, i.e. bound / filtered and desorbed, i.e. released, CO2 from the adsorption-desorption chamber. The closing unit can also be designed to close the freight container outer wall by means of closing elements, e.g. rotatable flaps and / or slats, so that the fan unit forms a closed wall section of the freight container outer wall, in particular for the desorption process. The closing unit can also have one or more doors, in particular sliding doors, as a closing element.

[0055] The control unit can be designed to be connected to other control units and / or a central control unit by means of radio transmission such as Wi-Fi, Bluetooth, near-field communication, etc.

[0056] Understandably, the adsorption fan module may also comprise other components, such as components for generating and / or distributing a desorption gas (e.g. water vapor) and / or separation elements (e.g. liquid traps).

[0057] Advantageously, the adsorption fan module further comprises at least one electrical connection, in particular an electrical plug connection for electrical connection to the adsorption chamber module.

[0058] Advantageously, several fan modules can be directly electrically or fluidically coupled to each other. Fan modules attached to the same freight container, in particular, can have connections for power or fluids, thus avoiding the need for additional cables.

[0059] It is also advantageous if the at least one adsorption fan module is detachably attached to the outside of the outer wall of the freight container of the adsorption chamber module or is accommodated in the adsorption-desorption chamber so that the external dimensions of the freight container of the adsorption chamber module remain unchanged during transport. Transport in the freight container is easily possible if the adsorption fan module has suitable external dimensions compared to openings in the freight container so that, for example, the adsorption fan module can be pushed into the freight container through the closable opening after being tilted and can be removed again on site. The adsorption fan module can be arranged together with the adsorber material in the adsorption-desorption chamber.However, the adsorbent material can also be transported separately, since changing the adsorbent material must be easy due to the expected degradation over time and the freight container would therefore be transported unnecessarily “empty” in future scenarios.

[0060] Drawings

[0061] The invention is explained in more detail below with reference to the accompanying drawings. They show:

[0062] Fig. 1 is a schematic representation of a CO2

[0063] Adsorption device according to the state of the art;

[0064] Fig. 2 is a schematic representation of a modular CO2 adsorption device according to the invention in a front view;

[0065] Fig. 3 is a schematic representation of a modular CO2 adsorption device according to the invention in a perspective view; and

[0066] Fig. 4 is a flow chart of a method for producing an adsorption chamber module according to the invention.

[0067] Fig. 1 shows a CO2 adsorption device 10 for separating CO2 (carbon dioxide) according to the prior art.

[0068] In comparison, Fig. 2 shows a modular CO2 adsorption device 20 according to the invention, which is also designed to separate CO2 (carbon dioxide) from a supplied air stream by means of a cyclically carried out adsorption-desorption process.

[0069] The CO2 adsorption device 10 and the modular CO2 adsorption device 20 each comprise a freight container 12; 22 in which an adsorption-desorption chamber 14; 24 is arranged for accommodating an adsorbent (not shown) for adsorbing the CO2 from the supplied air stream. The CO2 adsorption device 10 and the modular CO2 adsorption device 20 further each comprise a fan unit 16; 26 with fans 17; 27 for supplying the air stream into the respective adsorption-desorption chamber 14; 24 and a temperature control unit 18; 28 for controlling the temperature of the adsorbent for the adsorption-desorption process.

[0070] The CO2 adsorption device 10 and the modular CO2 adsorption device 20 also have closing elements 19; 29 for closing the respective adsorption-desorption chamber 14; 24.

[0071] As can be seen from Fig. 1, in the CO2 adsorption device 10 according to the prior art, the fans 17 of the fan unit 16 are arranged in the freight container 12, i.e., within the external dimensions of the freight container 12. The same applies to the temperature control unit 18 and the closing elements 19. This severely limits the installation space within the freight container 12, particularly for the adsorption-desorption chamber 14.

[0072] In contrast, the CO2 adsorption device 20 according to the invention from Fig. 2 is modular and has an adsorption chamber module 30 and a separate adsorption fan module 40, which is detachably attached to the outside of the freight container 22, ie outside the dimensions of the freight container 22 of the adsorption chamber module 30.

[0073] Specifically, the voluminous fan unit 26 with the fans 27 has been "separated" from the freight container 22 into the external adsorption fan module 40 according to the invention or into a fan module housing 42 of the adsorption fan module 40, wherein the air flow can still be fed into the adsorption-desorption chamber 24 by means of the fan unit 26 of the adsorption fan module 40 via an inlet channel (not shown) of the adsorption chamber module 30. The same applies to the temperature control unit 28 and one of the closing elements 29. Thus, the freed-up space can be used to enlarge the adsorption-desorption chamber 24. Accordingly, the adsorption chamber module 30 according to the invention only has the freight container 22 with the adsorption-desorption chamber 24, which now has a larger capacity than the adsorption-desorption chamber 14 according to the prior art from Fig.1 has a much larger volume.

[0074] This allows the external dimensions of the freight container to be maintained for transport and, at the same time, by "separating" the voluminous fan unit 26 and the other units 28, 29 into the separate adsorption fan module 40 - which can only be removably attached on site (outside the main dimensions of ISO 668) - a much larger volume of the freight container 22 can be used as an adsorption-desorption chamber 24 for the adsorbent material to be cyclized.

[0075] For the detachable attachment of the adsorption fan module 40 to the adsorption chamber module 30, the freight container 22 has a receiving unit 36 ​​on an outer side 32 of a lateral freight container outer wall 34. Similarly, the fan module housing 42 of the adsorption fan module 40 has an engagement unit 44. The receiving unit 36 ​​of the adsorption chamber module 30 and the engagement unit 44 of the adsorption fan module 40 are designed to form a detachable, positive-locking connection, which will be explained in more detail below in the description of Fig. 3.

[0076] Fig. 3 shows a schematic representation of another modular CO2 adsorption device 20 according to the invention in a perspective view.

[0077] From this, it can be seen, firstly, that the receiving unit 36 ​​is arranged on a long side of the freight container 22, so that the at least one adsorption fan module 40 is detachably fastened to the long side. The receiving unit 36 ​​has a load-bearing area 46 on the outer side 32 of the long-side freight container outer wall 34 with two lower load-bearing points 48a, onto which the adsorption fan module 40 is placed, and two upper load-bearing points 48b, to which the adsorption fan module 40 is fixed. Secondly, it can be seen that, due to the increased volume of the adsorption-desorption chamber 24, it is now suitable and designed to accommodate the adsorption fan module 40 for transport purposes, so that the external dimensions of the freight container 22 remain unchanged during transport.For this purpose, the adsorption-desorption chamber 24 has a correspondingly dimensioned, in particular closable opening 50, through which the at least one adsorption fan module 40 can be introduced into the adsorption-desorption chamber 24 for transport and removed again for assembly and commissioning.

[0078] Fig. 4 shows a flowchart of a method 100 for producing an adsorption chamber module 30 for a modular CO2 adsorption device 20 for separating CO2 from a supplied air stream by means of an adsorption-desorption process. The method 100 comprises a step of providing 102 a freight container 22, which is designed in particular according to ISO 668, as the chamber module housing 22. The method 100 further comprises a step of forming 104 an adsorption-desorption chamber 24 in the freight container 22 for accommodating an adsorbent for adsorbing the CO2 from the supplied air stream. The method 100 also includes a step of forming 106 an inlet channel for supplying the air stream into the adsorption-desorption chamber 24. The method 100 further includes a step of forming 108 an outlet channel for discharging the CO2-reduced air stream from the adsorption-desorption chamber 24.The method 100 finally comprises a step of forming 110 a receiving unit 36 ​​on the freight container 22 for releasably fastening at least one adsorption fan module 40 of the modular CO2 adsorption device 20 to an outer side 32 of a freight container outer wall 34 in order to guide the air flow by means of a fan unit 26 of the adsorption fan module 40 via the inlet channel into the adsorption-desorption chamber 24.

[0079] If an embodiment comprises an “and / or” link between a first feature and a second feature, this is to be read as meaning that the embodiment according to one embodiment has both the first feature and the second feature and according to another embodiment has either only the first feature or only the second feature.
