Capturing carbon dioxide

A system for removing CO2 from a dilute gas mixture, the system comprising:

• a frame comprising a plurality of structural members;
• at least one packing section comprising one or more packing sheets, the one or more packing sheets comprising a plurality of macrostructures;
• one or more bottom basins positioned at least partially below the at least one packing section relative to a flow of a CO2 capture solution along the at least one packing section, the one or more bottom basins configured to hold the 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 comprising one or more top basins for the CO2 capture solution, the one or more top basins for the CO2 capture solution configured to direct the CO2 capture solution to the at least one packing section at a liquid loading rate in a range from 0.5 L/m2s to 5.0 L/m2s, the liquid distribution system comprising one or more redistribution systems positioned above the one or more bottom basins and within the at least one packing section.
