1. A method to remove carbon dioxide (CO2) gas from a first gaseous feed and a second gaseous feed, the method comprising:
wetting a gas-liquid contactor with an alkaline capture solution;
receiving the first gaseous feed from a first source, the first gaseous feed comprising CO2;
directing a first flow from the first gaseous feed to interact with the alkaline capture solution in the gas-liquid contactor, wherein directing the first flow causes a first portion of CO2 from the first gaseous feed to dissolve into the alkaline capture solution forming a first CO2-rich alkaline capture solution;
receiving the second gaseous feed from a second, distinct source, the second gaseous feed comprising CO2;
directing a second flow from the second gaseous feed to interact with the first CO2-rich alkaline capture solution, wherein the second flow is independent of the first gaseous feed, and directing the second flow causes a second portion of CO2 from the second gaseous feed to dissolve into the first CO2-rich alkaline capture solution forming a second CO2-rich alkaline capture solution, and a concentration of CO2 in the second CO2-rich alkaline capture solution is higher than a concentration of CO2 in the first CO2-rich alkaline capture solution; and
separating a third portion of CO2 from the second CO2-rich alkaline capture solution.
