Abstract: A perforated packing for capturing carbon dioxide (CO2) from a dilute gas mixture includes at least one perforated mg) structure and a feed structure. The at least one perforated structure includes a body that includes at least one wall defining an inner volume of the body and an outer surface exposed to the dilute gas mixture; and a plurality of perforations extending through the at least one wall between the inner volume and the outer surface. The feed structure is fluidly coupled to the body and operable to flow a CO2 capture solution into the inner volume of the body, through the plurality of perforations, and along the outer surface to form a liquid film of the CO2 capture solution along at least part of the outer surface, the liquid film of the CO2 capture solution configured to absorb CO2 from the dilute gas mixture.

Abstract: A system for removing CO2 from a dilute gas mixture includes a frame including a plurality of structural members; at least one packing section including one or more packing sheets, the one or more packing sheets including a plurality of macrostructures; one or more basins positioned at least partially below the at least one packing section, the one or more basins configured to hold a CO2 capture solution; at least one fan positioned to circulate a CO2 laden gas through the at least one packing section; and a liquid distribution system configured to flow the CO2 capture solution onto the at least one packing section.

Abstract: A gas-liquid contactor for capturing carbon dioxide (CO2) from ambient air includes a flow system comprising: a top basin containing a CO2 capture solution, and a liquid distribution pipe in fluid communication with a turbine nozzle. A pump flows the CO2 capture solution to the turbine nozzle to emit a pressurized flow of the CO2 capture solution. A hydraulic fan comprises a shaft, a hydraulic turbine mounted to the shaft, and fan blades mounted to the shaft. The fan blades are positioned adjacent to an outlet, and the hydraulic turbine is positioned adjacent to the turbine nozzle and rotates upon the pressurized flow of the CO2 capture solution from the turbine nozzle impacting the hydraulic turbine. Rotation of the hydraulic turbine causes rotation of the fan blades, circulation of the ambient air through an inlet and circulation of a CO2-lean gas through the outlet. Related systems and methods are disclosed.
