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.

In some implementations, a system for removing oxygen from a container includes a recirculation pump and an oxygen removal device. The recirculation pump includes an intake and a discharge, and the intake includes a first connector. The discharge is fluidically connected to an oxygen removal device.

An apparatus for collecting a gaseous pollutant from air may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.

A heater element with a functional material-containing layer includes: a honeycomb structure including an outer peripheral wall and partition walls disposed on an inner side of the outer peripheral wall, the partition walls defining a plurality of cells, each of the cells extending from a first end face to a second end face to form a flow path, at least the partition walls being made of a material having a PTC property; a pair of electrodes provided on the first end face and the second end face of the honeycomb structure; and a functional material-containing layer provided on a surface of the partition walls.

A vehicle includes a fuel tank and an evaporative-emissions system having a primary subsystem and an auxiliary subsystem. The primary subsystem has a fuel-vapor canister in fluid communication with the fuel tank to capture fuel vapors of the fuel tank. The auxiliary subsystem is configured to capture fuel vapors associated with an external fuel-storage device. The auxiliary subsystem has an auxiliary port located on an exterior of the vehicle and is configured to connect with the external fuel-storage device. The auxiliary port is selectively connected in fluid communication with the fuel-vapor canister by a valve.

The fog removal apparatus comprises a plurality of fog barriers for removing moisture in the fog by absorbing moisture in the fog and by allowing air to pass therethrough when the fog passes through the fog barrier on the wind, and a fog barrier support for supporting the fog barrier. The fog barrier comprises a perforated plate arranged on an outer surface of the frame to support the fog barrier; a coated mesh having a porous waterproofing function; a super absorbent sheet for absorbing a large amount of moisture from the fog passing through the fog barrier; a heating means arranged adjacent to the super absorbent sheet to heat and dry the coated mesh and the super absorbent sheet.

The direct air capture (DAC) systems and methods efficiently and economically regenerate a desiccant bed without adding any thermal energy and without requiring any pressurization or depressurization of the desiccant reactors. The methods leverage water concentration differences in stream flows, the water concentration profile across a desiccant bed, and, optionally, exothermic water adsorption. These three elements, working in combination, are referred to as “reverse dry flow regeneration” or a “reverse dry air swing” regeneration process. Systems and methods for reverse flow regeneration include those for CO.sub.2 DAC applications, but they are also applicable to point source carbon capture and other similar technologies that require initial gas dehydration before exposure to a hydrophilic material.

A system for capturing and sequestering carbon dioxide includes nanoparticles formed from alkali or alkali metal oxides or hydroxides, such as lithium oxide. Carbon-dioxide containing effluent gasses are exposed to the nanoparticles in fixed beds or fluidized beds, or in a co-flow configuration. The nanoparticle metal oxides are converted to metal carbonates. The nanoparticles can be recovered and the carbon dioxide release by exposing the nanoparticles to an oxygen containing atmosphere at high temperatures.

A system and method of regenerating a pre-purification vessel is provided that is particularly suitable for pre-purification of a feed air stream in cryogenic air separation unit that uses an oxygen-enriched purge gas stream for regeneration of the pre-purification unit. The disclosed pre-purification systems and methods are configured to remove substantially all of the water, carbon dioxide and other impurities from a feed air stream, optionally including hydrogen and carbon monoxide impurities. The method of regenerating a pre-purification vessel preferably involves regenerating the pre-purification vessel with an oxygen-enriched purge gas after depressurization of the vessel and thereafter partially repressurizing the pre-purification vessel with an auxiliary purge gas thereby diluting the oxygen concentration of the gases contained in the pre-purification vessel and optionally depressurizing the partially repressurized vessel.

An excellent hygroscopic material containing a temperature responsive polymer, which can efficiently conduct heat, and hence has water release properties of absorbed water is realized. The hygroscopic material containing a polymer gel containing a temperature responsive polymer whose affinity with water reversibly changes in response to temperature stimulation and a thermally conductive filler is used.
