[0011] Detailed explanation An embodiment of a CO2 isolation and / or recovery cooling system 100 for an electrical transformer ("transformer") 110 will be described with general reference to Figures 1A to 5. The transformer 110 includes a cooling fan 120 having an air inlet 130 and an air outlet 140.

[0012] In the embodiment shown in Figure 1A, the CO2 isolation and / or recovery cooling system 100 includes a CO2 isolation and / or recovery module 170 configured to be coupled to at least one of the air inlet 130 and air outlet 140 of a cooling fan 120 of a transformer 110. The CO2 isolation and / or recovery module 170 is further configured to separate CO2 from ambient air, which is at least one of the air received at the air inlet 130 of the cooling fan 120 and the air exiting from the outlet 140 of the cooling fan 120.

[0013] Referring to Figure 1B, the CO2 sequestration and / or recovery module 170 is one of the following: a membrane and / or solid material (e.g., granules, pellets) CO2 sequestration and / or recovery module 172, a chemical CO2 sequestration and / or recovery module 174, and a combined membrane, solid and / or chemical CO2 sequestration and / or recovery module 176 arranged within the housing 150. The technical advantages of solid CO2 recovery materials are that they are easy to handle and encapsulate, and / or that air pressure drops due to incomplete stacking are reduced. The technical advantages of the chemical CO2 sequestration and / or recovery module 174 are that it is a single unit or component that can physically hold CO2 and allow flushing of CO2 through liquid splashing or a similar process, is easy to install in a container, is easy to operate and replace, and is easy to visually inspect for maintenance. The technical advantages of the chemical CO2 sequestration and / or recovery module 174 are its CO2 retention efficiency and ease of circulation in the flushing process. The technical advantage of the combined membrane, solid, and / or chemical CO2 sequestration and / or recovery module 176 compared to the other modules 172 and 174 is that it includes a combination of the above-mentioned technical advantages of modules 172 and 174.

[0014] Referring to Figure 1C, the cooling fan 120 may also be part of a radiator fan type 182 of a cooling system 184 that includes a small insulated liquid-air cooler 180, in particular an oil-air cooler 180, or a transformer cooling element (e.g., a radiator) 190 through which ambient air passes and generates ambient air heated by the transformer. The ambient air heated by the transformer may be used to partially raise the temperature of the CO2 sequestration and / or recovery module 170 to a desired set temperature (e.g., about 100–120°C) for flushing CO2 from the CO2 sequestration and / or recovery module 170. While 100–120°C is provided as an example of a desired set temperature, the desired set temperature may vary along with the adsorbent efficiency. The high-temperature air at the inlet point of the recovery module 170 may also minimize the effects of moisture, which is more common than CO2 in the air, thus reducing the need to separate the recovered CO2 from the recovered moisture. As used herein, high-temperature air is air above the ambient temperature (e.g., above 15–25°C).

[0015] Referring particularly to FIG. 2, one embodiment of a cooling system 100 for CO2 isolation and / or recovery includes a housing 150 having an air inlet 160 configured to be coupled to an air inlet 130 and an air outlet 162 of a cooling fan 120 of a transformer 110. Ambient air is received at the air inlet 160 of the housing 150, and CO2-reduced air from the CO2 isolation and / or recovery module 170 is delivered to the air inlet 130 of the cooling fan 120 via the housing air outlet 162. CO2 is flashed from the CO2 isolation and / or recovery module 170 by raising the temperature of the CO2 isolation and / or recovery module 170 to a desired flashing set temperature, for example, but not limited to, the method described in more detail below with respect to FIG. 5. The flashed CO2 may be supplied and / or directed to a CO2 storage / isolation system, which is schematically shown by the cylinder of FIG. 2. The flashed CO2 may, for example, but not limited to, be mixed with water and buried underground, compressed and / or bottled for commercial use (e.g., chemical industry, carbonated beverages, pharmaceuticals), used for stone formation / growth by carbon mineralization (e.g., CO2 reacting rocks), and used in a CO2-optimized greenhouse for growing plants. The technical advantage of this embodiment is to generate an air flow through the CO2 isolation and / or recovery module 170 using the already operating cooling fan 120 to isolate and / or recover CO2.

[0016] Referring to FIGS. 3A and 3B, an additional embodiment of the cooling system 100 for CO2 isolation and / or recovery will be described.

[0017] In FIG. 3A, the housing air outlet 162 is configured to be coupled to the air inlet 130 of the cooling fan 120 such that air flows through the housing 150 at ambient temperature and CO2-reduced air from the CO2 recovery module 170 flows out of the housing air outlet 162 at ambient temperature. The CO2-reduced air at ambient temperature may be heated by the transformer cooling element 190 of the transformer 110 and exit the cooling fan 140 at the air outlet 140.

[0018] In FIG. 3B, the housing air inlet 160 is configured to be coupled to the air outlet 140 of the cooling fan 120, ambient air is delivered from the cooling fan 120 through the air inlet 160 of the housing 150, and CO2-reduced air from the CO2 isolation and / or recovery module 170 is delivered from the housing 150 via the housing air outlet 162. In this embodiment, the ambient air delivered from the cooling fan 120 to the CO2 isolation and / or recovery module 170 is heated by the transformer cooling element 190 of the transformer 110, particularly typically up to 50 - 60 °C, and is the ambient air heated by the transformer that is discharged or sucked by the cooling fan 120 away from the transformer 110. CO2 is optionally first recovered from the air, and then, after saturation of the material, the temperature of the CO2 isolation and / or recovery module 170 is raised to a desired flashing set temperature based at least in part on the ambient air heated by the transformer, and / or the temperature of the already high-temperature adiabatic liquid is raised to a desired set temperature, such that, as will be described in more detail below with respect to FIG. 5, particularly FIGS. 5 - 11B, the CO2 is more efficiently flashed from the CO2 isolation and / or recovery module 170. The technical advantage of this embodiment is that the ambient air delivered from the cooling fan 120 to the CO2 isolation and / or recovery module 170 and / or the high-temperature adiabatic liquid at the inlet point of the cooling system is at a significantly higher temperature than the ambient temperature, reducing the need for additional energy to raise the temperature of the CO2 isolation and / or recovery module 170 to the desired flashing set temperature, particularly the desired CO2 recovery and flashing set temperature.

[0019] Referring to Figures 4A and 4B, a further embodiment of the CO2 isolation and / or recovery cooling system 100 includes a housing air inlet 160 configured to be coupled to the air outlet 140 of a cooling fan 120 via an upstream transformer cooling element 190 of the transformer 110, with ambient air delivered from the cooling fan 120 through the transformer cooling element 190 and through the air inlet 160 of the housing 150, and CO2-reduced air from the CO2 isolation and / or recovery module 170 delivered from the housing 150 via a housing air outlet 162. CO2 is flushed from the CO2 isolation and / or recovery module 170 by raising the temperature of the CO2 isolation and / or recovery module 170 to a desired flushing set temperature, in a manner described in more detail below with respect to Figure 5, particularly Figures 5 to 11B. In Figure 4A, the cooling fan 120 may be positioned laterally / horizontally relative to the CO2 isolation and / or recovery module 170 and / or radiator, whereas in Figure 4B, the cooling fan 120 may be positioned vertically (e.g., downward) relative to the radiator and the CO2 isolation and / or recovery module 170. The technical advantage of this embodiment, and in particular these embodiments, is that the air delivered from the cooling fan 120 to the CO2 isolation and / or recovery module 170, especially the ambient air, is significantly hotter than the ambient temperature, minimizing the effect of capturing moisture along with the CO2 and / or reducing the need for additional energy to raise the temperature of the isolation and / or CO2 isolation and / or recovery module 170 to the desired flushing set temperature.

[0020] Referring to Figure 5, a CO2 isolation and / or recovery cooling system 100, which may be any of the embodiments in Figures 1A to 4B, includes a temperature control system 200 configured to control the heating of the CO2 isolation and / or recovery module 170 to a desired set temperature 214 from which CO2 is flushed. The shown temperature control system 200 is a control loop type temperature control system 200 comprising a temperature sensor 210 configured to sense the actual temperature of the CO2 isolation and / or recovery module 170 (the actual temperature 212 of the system from which the CO2 is flushed), and / or a cooling element temperature sensor 220 configured to sense the temperature associated with the transformer cooling element 190 of the transformer 110 (e.g., the temperature of an adiabatic liquid, particularly a relatively high-temperature adiabatic liquid). The controller 230 is configured to compare the sensed temperature in the CO2 isolation and / or recovery module 170 with a desired flushing set temperature 214 and / or monitor the cooling element temperature sensor 220 to determine whether the CO2 isolation and / or recovery module 170 requires further heating by one or more heater units 232 (e.g., electric heaters such as resistance heating units, immersion heaters and control systems, and / or thermal tracers and control systems) up to the desired set temperature 214 for flushing CO2 from the CO2 isolation and / or recovery module 170. The controller 230 may include one or more electrical circuits, one or more processors, and / or one or more electrical elements (e.g., relays 234, comparators 236) to control one or more heater units 232 to heat the CO2 isolation and / or recovery module 170 to the desired flushing set temperature 214. In the example where the heater units 232 are electric, power is supplied to one or more heater units 232 from an adjacent transformer 110.In the embodiment of the CO2 isolation and / or recovery cooling system 100 shown in Figures 3A to 4B, the temperature of the CO2 isolation and / or recovery module 170 may be raised to a desired flushing set temperature 214 based at least partially on ambient air and / or high-temperature adiabatic liquid heated by the transformer, so that less heat or power needs to be supplied from the transformer 110 to one or more heater units 232 to raise the temperature of the CO2 isolation and / or recovery module 170 to the desired flushing set temperature 214. The technical advantage of the temperature control system 200 is that it optimizes the method 240 described below so that the CO2 isolation and / or recovery and CO2 flushing processes are carried out at the desired flushing set temperature 214. Referring to Figure 6, the method 240 using the CO2 isolation and / or recovery cooling system 100 is described here. In block 250, the CO2 isolation and / or recovery module 170 receives ambient air, which is received into the air inlet 130 of the cooling fan 120 of the transformer 110 and exits from the outlet 140 of the cooling fan 120 (or the miniature cooler in Figure 3A or Figure 3B). In block 260, the CO2 isolation and / or recovery module 170 separates CO2 from the ambient air, which is received into the air inlet 130 of the cooling fan 120 of the transformer 110 and exits from the outlet 140 of the cooling fan 120 (or the miniature cooler in Figure 3A or Figure 3B). In other embodiments, one or more operations shown in blocks 270-320 may be performed. In block 270, the temperature 212 of the CO2 isolation and / or recovery module 170 is received by the controller 230. In block 280, the temperature 212 received by the CO2 isolation and / or recovery module 170 is compared by the controller 230 to a desired flushing set temperature 214. In block 290, the controller 230 controls one or more heater units 232 to raise the temperature 212 of the CO2 isolation and / or recovery module 170 to a desired set temperature 214 for flushing CO2 from the CO2 isolation and / or recovery module 170.In block 300, ambient air and / or high-temperature insulating / heat transfer liquid heated by the transformer is delivered to the CO2 isolation and / or recovery module 170. In block 310, the delivered ambient air and / or high-temperature insulating / heat transfer liquid heated by the transformer is heated to a desired set temperature 214 for flushing CO2 from the CO2 isolation and / or recovery module 170. In block 320, one or more heater units 232 receive power from an adjacent transformer 110.

[0021] Referring to Figure 7, another embodiment of the CO2 recovery cooling system 400 for a transformer 110 for removing CO2 from the air is described. Similar to the CO2 recovery cooling system 100, the CO2 recovery cooling system 400 comprises a CO2 recovery module 170 configured to be coupled to at least one of the air inlet 130 and air outlet 140 of the cooling fan 120 of the transformer 110. The CO2 recovery module 170 is also configured to be coupled to a CO2 recovery module high-temperature heat transfer liquid heat transfer system ("CO2 HTS") 410, which is configured to be coupled to the transformer cooling system or transformer high-temperature adiabatic liquid heat transfer system ("T HTS") 420 of the transformer 110. As used herein, high-temperature adiabatic liquids include mineral oils, natural esters, synthetic esters, silicone fluids, LFHs (less flammable hydrocarbons), bio-based hydrocarbons, or other adiabatic liquids that are above ambient temperature (e.g., above 15-25°C). A description of the CO2 recovery cooling system 100 and temperature control system / method relating to Figures 1A to 6 is incorporated herein.

[0022] Referring to Figure 8, the transformer high-temperature adiabatic liquid heat transfer system 420 is shown in more detail. The transformer high-temperature adiabatic liquid heat transfer system 420 includes a heat exchanger 430, a high-temperature adiabatic liquid manifold 440, and a low-temperature oil outlet 450. The high-temperature adiabatic liquid used to transfer heat from the transformer 110 to cool the transformer 110 enters the heat exchanger 430 in the high-temperature adiabatic liquid manifold 440 (for example, at about 80-90°C (176-194°F)) and exits the heat exchanger 430 in the low-temperature adiabatic liquid manifold 450. One or more cooling fans 120 blow air through the heat exchanger 430, cooling the high-temperature adiabatic liquid passing through the heat exchanger 430 and heating the air delivered to the CO2 recovery module 170. As shown in Figure 7, in an alternative embodiment, the CO2 recovery module 170 may be coupled to at least one of the air inlet 130 and air outlet 140 of the cooling fan 120 of the transformer 110 (or the small cooler in Figure 3A or Figure 3B).

[0023] Referring to Figure 9, one embodiment of the CO2 recovery module high-temperature heat transfer liquid heat transfer system 460 is shown in more detail. The CO2 recovery module high-temperature heat transfer liquid heat transfer system 460 includes a CO2 recovery module heat exchanger 470 and conduits 480 coupled to ports 490, 500 of a high-temperature adiabatic liquid manifold 440. Waste energy high-temperature adiabatic liquid (e.g., about 80-90°C) from the high-temperature adiabatic liquid manifold 440 is transferred to and from the CO2 recovery module heat exchanger 470 via conduits 480. For CO2 desorption, the CO2 recovery module high-temperature heat transfer liquid heat transfer system 460 transfers heat from the high-temperature adiabatic liquid of the transformer high-temperature adiabatic liquid heat transfer system 420 to the CO2 recovery module 170 via the CO2 recovery module heat exchanger 470 and conduits 480. The waste energy high-temperature insulated liquid in the high-temperature insulated liquid manifold 440 may exit the high-temperature insulated liquid manifold 440, enter the CO2 recovery module high-temperature heat transfer liquid heat transfer system 460 at port 490, and return from the CO2 recovery module high-temperature heat transfer liquid heat transfer system 460 to the high-temperature insulated liquid manifold 440 at port 500. By using the waste energy high-temperature insulated liquid from the transformer high-temperature insulated liquid heat transfer system 420 to flush CO2 from the CO2 recovery module 170, the energy required from other energy sources to raise the temperature of the CO2 recovery module 170 to the desired set temperature for releasing CO2 for storage for CO2 desorption is reduced. While the "typical" energy consumption per ton of CO2 in conventional systems is in the range of approximately 1500 kWh / ton, using the CO2 capture cooling system 400 reduces the energy consumption per ton of CO2 to 360 kWh / ton (a reduction of approximately 75%). The CO2 capture module 170 needs to operate at or near ambient temperature (or a temperature considerably lower than the desorption temperature, e.g., in the range of 100-120°C) in order to capture CO2.The flushed CO2 exits the CO2 recovery module 170 at outlet 510 and passes through one or more conduits 520 to be stored in a container 530 (for example, for future use) or for other purposes.

[0024] In an alternative embodiment, the CO2 recovery module 170 may be coupled to at least one of the air inlet 130 and air outlet 140 of the cooling fan 120 of the transformer 110.

[0025] Referring to Figure 10, an additional embodiment of the CO2 recovery module high-temperature heat transfer liquid heat transfer system 550 is shown in more detail. The CO2 recovery module high-temperature heat transfer liquid heat transfer system 550 includes a high-temperature heat transfer liquid bath heat transfer circulation system 560 and a CO2 recovery module heat exchanger circulation system 570.

[0026] The high-temperature heat transfer liquid bath heat transfer circulation system 560 includes a high-temperature heat transfer liquid bath 580 and conduits 480 connected to ports 490, 500 of a high-temperature insulated liquid manifold 440 and a CO2 recovery module heat exchanger 470.

[0027] The CO2 recovery module heat exchanger circulation system 570 includes a CO2 recovery module heat exchanger 470 and conduits 480 connected to the end port 590 of a high-temperature insulated liquid manifold 440 and the end port 600 of a low-temperature insulated liquid manifold 450.

[0028] The waste energy from the high-temperature insulated liquid manifold 440 (e.g., about 80-90°C) is transferred to the CO2 recovery module heat exchanger 470, which may include a fan 605 in a conventional cooler, and returned to the high-temperature insulated liquid manifold 440 via the conduit 480. The CO2 recovery module high-temperature heat transfer liquid heat transfer system 550 transfers heat from the high-temperature insulated liquid of the transformer high-temperature insulated liquid heat transfer system 420 to the CO2 recovery module 170 via the CO2 recovery module heat exchanger 470 and the conduit 480 to a desired set temperature for CO2 desorption (e.g., about 100-120°C). If additional heat is required to raise the CO2 recovery module 170 to a desired set temperature (e.g., approximately 100-120°C) for CO2 release / CO2 desorption, a high-temperature adiabatic liquid (e.g., 100-120°C) from the high-temperature heat transfer liquid bath 580 is transferred to the CO2 recovery module heat exchanger 470 via the high-temperature heat transfer liquid bath heat transfer circulation system 560.

[0029] The flushed CO2 is drawn out of the CO2 recovery module 170 via a vacuum pump 620, exits the CO2 recovery module 170 at an outlet 510, passes through one or more conduits 520 to a condenser 630 where moisture is removed, and can then be delivered via a compressor 640 for various applications (e.g., connection to a CO2 pipeline, underground injection, bottle transport, local storage in a tank). In an alternative embodiment, the CO2 recovery module 170 may be coupled to at least one of the air inlet 130 and air outlet 140 of a cooling fan 120 of a transformer 110.

[0030] While the CO2 recovery module high-temperature heat transfer liquid heat transfer system 550 is shown with respect to a fan and radiator, in an alternative embodiment, the CO2 recovery module high-temperature heat transfer liquid heat transfer system 550 is applied to a small cooler shown in Figure 3A and / or Figure 3B.

[0031] Referring to Figures 11A and 11B, one embodiment of a combined CO2 recovery and transformer adiabatic liquid heat exchanger system 650, including a CO2 recovery module heat exchanger 470 and a CO2 recovery module 170, is described. The combined CO2 recovery and transformer adiabatic liquid heat exchanger system 650 includes a housing 660 having side walls 670 and end walls 680. The housing 660 houses the CO2 recovery module heat exchanger 470, which may be a small cooler, and includes an inlet 690 of a CO2 recovery module heat exchanger circulation system 570 along one end wall 680, and also includes an inlet 710 and an outlet 720 of a high-temperature heat transfer liquid bath heat transfer circulation system 560 along the other end wall 680. The CO2 recovery module heat exchanger 470 transfers heat from a transformer adiabatic liquid (e.g., high-temperature adiabatic liquid) to a separated heat transfer liquid, which is then circulated through the adsorption material of the CO2 recovery module 170 for CO2 desorption. A vacuum connection 730 for extracting CO2 from the CO2 recovery module 170 via a vacuum pump 620 is located along the opposite end wall 680. The side wall 670 may include a control perforation / air inlet 740 for supplying air to the transformer cooling system to remove heat from the adiabatic liquid. The inner wall is a metal structure or mechanical blind adjacent to a louver 750 to control the air inlet 740 and seal chamber 760 for vacuum and CO2 extraction / desorption stages. When closed, the louver 750 allows for the establishment of a vacuum within the CO2 recovery module 170, which helps extract CO2 from the adsorbent material along with the high temperature from the high-temperature heat transfer liquid circulation around the adsorbent material.

[0032] The method for controlling the heat of the CO2 recovery module 170 to a desired set temperature 214 using the CO2 recovery cooling system 400 is the same as that described and illustrated herein with respect to the CO2 recovery cooling system 100 and Figures 5 and 6, which are incorporated herein by reference. The high-temperature heat transfer liquid is circulated within the CO2 recovery module high-temperature heat transfer liquid heat transfer systems 460, 550, and heat is transferred from the circulated high-temperature heat transfer liquid to the CO2 recovery module 170. Since the high-temperature adiabatic liquid operates in the range of 70-90°C, the energy required for the CO2 recovery module 170 to reach the exemplary range of 100-120°C for CO2 removal in the desorption process is far less compared to delivering only ambient air heated by a transformer to the CO2 recovery module 170. In the CO2 recovery module high-temperature heat transfer liquid heat transfer systems 460 and 550, the circulation of the high-temperature heat transfer liquid heat transfer liquid heats the CO2 recovery module 170 to a desired set temperature for flushing CO2 from the CO2 recovery module 170 after CO2 has been flushed from the CO2 recovery material, and is stopped until the next cycle after the CO2 has been removed from the CO2 recovery module 170. In some applications, the CO2 recovery material may need to operate at ambient temperature to remove CO2 from the air (adsorption process), while other materials may need to operate at around 50-60°C during the recovery phase. All systems require higher temperatures (e.g., 100-120°C) to remove the recovered CO2 from the material (desorption process).
