A carbon abatement system includes at least one carbon abatement panel including a carbon abatement material. The at least one carbon abatement panel is rotatable about an axis to maximize exposure of the carbon abatement material to sunlight.

A carbon processing system comprises an air mover and a multi-stage reactor. The multi-stage reactor processes ambient air and generates carbon dioxide and generates exhausted gas released to ambient air. In operation, air contacts the base solution via the air mover. The air reacts with the base solution thereby generating a base solution having carbon dioxide and generating exhaust (absorption reaction). Next, the exhaust is released from the reactor. Next, heat is applied to the base solution having carbon dioxide thereby generating carbon dioxide and generating a base solution without carbon dioxide (desorption reaction). The base solution without carbon dioxide generated after applying heat is reusable in processing new air. The absorption reaction and desorption reaction are reversible reactions resulting in regeneration of the base solution into its form prior to contact with the air yielding high scalability and less processing volume as required by many conventional carbon processing techniques.

Carbon sequestering infrastructure incorporates carbon-sequestering cladding members that are separate and distinct from structural elements configured to carry a structural load of the infrastructure. The cladding is capable of capturing and sequestering carbon from carbon dioxide in atmospheric/ambient air. The cladding may be distinct members having a high carbon capture capacity (but a low compressive strength unsuitable for use in a structural member) attached to structural members having a lower carbon capture capacity (and a higher compressive strength suitable for use in a structural member). The cladding member may be formed as an envelope suitable for use as a form in casting a structural member. Infrastructure elements including cladding may be configured such that the cladding is removable and replaceable after is carbon sequestering capacity is diminished, to allow for carbon sequestration over the entire length of the infrastructure.

This disclosure teaches a composition and process which makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting of a solution that readily captures any particulate material in the air. More specifically, the present disclosure teaches the composition and use of aromatic compounds that are semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants as the misting/fogging agent for dust suppression. The particulate material is lowered to surfaces and removed by vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). This method can be achieved with neutral air pressure differentials in the work areas.

A carbon dioxide capture and sequestration system is provided and includes a capture unit, a storage unit, a sequestration unit and a floating body unit. The capture unit is used for capturing carbon dioxide in the atmosphere; the storage unit is connected with the capture unit and is used for storing the carbon dioxide captured by the capture unit; the sequestration unit is connected with the storage unit and is used for sequestrating the carbon dioxide discharged by the storage unit. The capture unit, the storage unit and the sequestration unit are all arranged on the floating body unit so as to float on the sea. The system can sequestrate the captured carbon dioxide in situ and reduce the transportation cost.

The carbon capture system includes a wind turbine, a direct-air capture (DAC) system, and a processor. The wind turbine has a first location and/or a first position. The processor is communicatively coupled to the DAC system. The processor is configured to input a wind turbine wake from the wind turbine and/or incident carbon dioxide profile, execute an algorithm to determine a wind velocity and/or a concentration of the carbon dioxide in the wind turbine wake, and output a second location and/or a second position of the DAC system. The second location and/or the second position of the DAC system is optimized to enhance the quantity of carbon dioxide captured from to the wind turbine.

A system for generating liquid water from air is provided. The system includes an air current generating device and a body which allows a current of air from the air current generating device to flow therethrough. The body comprising a constricted portion through which the current of air passes from an inlet hereof to an outlet thereof, wherein cooled air that is at a temperature that is substantially at a dew point temperature of air is discharged at the outlet of the constricted portion thereby causing water in the air to condensate from the cooled air. A portion of the energy required to cool down the air is fed back to the input, requiring less energy to cool down air in subsequent cycles of air. Also provided is a corresponding method.

A carbon dioxide recovery device includes: an adsorption unit that includes a plurality of electrochemical cells, each of which includes a working electrode and a counter electrode; a receiver that receives the adsorption unit; a plurality of gas inlets, each of which is provided to the receiver and is configured to introduce a subject gas containing carbon dioxide; and a plurality of doors, each of which is configured to open and close a corresponding one of the gas inlets. The gas inlets are respectively configured to introduce the subject gas into an inside of the receiver in a corresponding direction perpendicular to a cell stacking direction of the electrochemical cells and are configured to introduce the subject gas into the receiver from all around the receiver along a circumferential direction of the receiver that is perpendicular to the cell stacking direction.

An air precleaner for centrifugally separating contaminants from an air stream, the precleaner having one or more of: each fin overlapping at least 30 percent of an immediately adjacent fin; a contoured inlet surface occurring over a distance of at least 8 mm into the annular air intake passage; each of the fins backwards inclined at least 30 degrees off radial; at least two exhaust ports oriented non-perpendicular to a long axis of the outer housing; a paddle assembly comprising a rotatable portion of the inner member of the air precleaner; and a paddle assembly wherein there is at least one fewer of the connection arms than the number of the discharge paddles.

Implementations of the disclosed subject matter provide a process for capture of carbon dioxide from a gaseous feed stream. The process may include a direct air capture unit comprising an inlet air section, a sorbent section, and an outlet air section. A gaseous feed stream may be received at the inlet air section and the feed stream may be contacted with a sorbent material in the sorbent section. An exit gaseous outlet stream may be provided from the outlet air section. The total pressure loss across the inlet and outlet air sections may be maintained at less than 200 Pa. The feed stream may have a volumetric flow within the sorbent section having a maximum and a minimum flow. The unit may include at least one structural element for maintaining the minimum flow to be within a range of 0-20% lower than the maximum flow over the entire sorbent section.
