The present disclosure includes various methods systems and apparatuses for carbon dioxide capture and utilization such as for encapsulation in asphalt. For example, a method can include combusting fuel to generate a flow of exhaust from a working machine operating to perform one or more asphalt related tasks, capturing CO2 from the exhaust, storing the CO2 in a storage unit onboard the working machine, forming asphalt that includes an amount of the CO2 from the storage unit by selectively mixing the amount of the CO2 from the storage unit with calcium, and using the asphalt that is formed that includes the amount of the CO2 from the storage unit encapsulated therein at a jobsite.

A carbon dioxide capture system includes a first capture tank containing carbon dioxide absorbent material which operates to absorb carbon dioxide from a flow of exhaust gas from an internal combustion engine. A heat exchange loop is in heat exchange communication with the first capture tank and further in heat exchange communication with one of the flow of exhaust gas or a flow of engine coolant from the internal combustion engine. A heat exchange fluid is operable to flow through the heat exchange loop. The heat exchange fluid operates to transfer heat from the exhaust gas or the engine coolant to the first capture tank. The heat from the exhaust gas or the engine coolant operates to release a portion of the carbon dioxide absorbed by the carbon dioxide absorbent material in the first capture tank.

A vehicle exhaust system and method of minimizing a leaked mass flow comprising an exhaust component defining a central axis and having an inner surface and an outer surface, such that the inner surface defines a primary exhaust gas flow path extending along the central axis from an inlet to an outlet, and a surface component having a hood spaced from the exhaust component to define a reservoir having a reservoir volume (V), the reservoir comprising a reservoir inlet fluidly coupled to the primary exhaust gas flow path and defining an inlet area (A), and a reservoir outlet fluidly coupled to an outside environment. The reservoir volume and inlet area having a defined relationship. The reservoir volume and a mass flow through the inlet area having a defined relationship.

A system for mobile carbon capture, preferably including a capture module, a regeneration module, and a storage module 130. The system can optionally include a thermal control module and/or a dehumidifier. A method for mobile carbon capture, preferably including adsorbing a target species, desorbing the target species, and storing the target species. The method can optionally include pre-treating input gas, offloading stored species, and/or regenerating desiccators.

A control system for a vehicle having a CO2 capturing device configured to capture CO2 certainly from gas streams. The CO2 captured by the CO2 capturing device is desorbed from the CO2 capturing device by an energy available in the vehicle. A controller is configured to discharge the CO2 captured by the CO2 capturing device into the recovery station by energy delivered from the recovery station to the CO2 capturing device when the energy available in the vehicle is less than a predetermined value.

A method of processing exhaust gas includes receiving incoming exhaust gas and cooling it in at least one heat exchanger to create cooled exhaust gas. The cooled exhaust gas is compressed in a compressor to liquefy CO.sub.2 leaving a remaining exhaust gas. The remaining exhaust gas is circulated through the heat exchanger to cool subsequent incoming exhaust gas and warm the remaining exhaust gas. At least a portion of the liquid CO.sub.2 may be pelletized in a pelletizer.

A sensor assembly for use within a flow conduit includes a sensor shield port extending between inner and outer ends of the sensor shield port through a wall of the flow conduit. The sensor shield port includes a port body defining a bore and extending between inner and outer surfaces of the port body. The sensor shield port further includes an outer port wall extending from the outer surface of the port body towards the outer end of the sensor shield port and an inner port wall extending from the inner surface of the port body. The sensor shield port includes one or more tabs extending from the inner port wall towards the inner end of the sensor shield port. The sensor assembly further includes an exhaust sensor inserted and removably coupled within the bore of the sensor shield port.

A method for purifying the exhaust gas generated by an internal combustion engine, wherein the exhaust gas generated by the internal combustion engine is conducted through an exhaust gas path in which at least one adsorption element is arranged, to which pollutants contained in the exhaust gas at least partly bind, and in which the at least one adsorption element is regenerated by at least partial desorption of the bound pollutants, and pollutants desorbed from the at least one adsorption element during the desorption process are stored in at least one storage unit.
