Abstract: Techniques for converting carbonate material to carbon monoxide include transferring heat and at least one feed stream that includes a carbonate material and at least one of hydrogen, oxygen, water, or a hydrocarbon, into an integrated calcination and syngas production system that includes a syngas generating calciner (SGC) reactor; calcining the carbonate material to produce a carbon dioxide product and a solid oxide product; initiating a syngas production reaction; producing, from the syngas production reaction, at least one syngas product that includes at least one of a carbon monoxide product, a water product or a hydrogen product; and transferring at least one of the solid oxide product or the at least one syngas product out of the SGC reactor.

Abstract: Techniques according to the present disclosure include capturing carbon dioxide from a dilute gas source with a CO2 capture solution to form a carbonate-rich capture solution; separating at least a portion of carbonate from the carbonate-rich capture solution; forming an electrodialysis (ED) feed solution; flowing a water stream and the ED feed solution to a bipolar membrane electrodialysis (BPMED) unit; applying an electric potential to the BPMED unit to form at least two ED product streams including a first ED product stream including a hydroxide; and flowing the first ED product stream to use in the capturing the carbon dioxide from the dilute gas source with the CO2 capture solution.

Abstract: A packing for capturing carbon dioxide (CO2) from a dilute includes at least one panel that includes a mesh material configured to be wetted by a CO2 capture solution and that defines a gas channel having a first dimension defined along a first direction and a second dimension defined along a second direction different than the first direction, the gas channel configured to receive a flow of CO2-laden gas from the dilute gas source in the second direction and contact the flow of CO2-laden gas with the CO2 capture solution on the mesh material.

Abstract: A system for capturing CO2 from a dilute gas source includes a gas-liquid contactor including a housing coupled to a plurality of structural members; one or more basins positioned within the housing and configured to hold a CO2 capture solution, the one or more basins including a bottom basin; one or more packing sections positioned at least partially above the bottom basin; a fan operable to circulate a CO2-laden gas through the one or more packing sections; and a liquid distribution system configured to flow the CO2 capture solution onto the one or more packing sections.

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.
