1. An apparatus for humidifying a gas stream, comprising:
inlet ports arranged to receive at least one feed stream into a hydration housing vessel;
a gas inlet section configured to receive at least one gas feed stream into the hydration housing vessel, the inlet ports and the gas inlet section coupled to the hydration housing vessel;
a hydration solution having a capacity for hydrating the at least one gas feed stream;
a contact zone coupled to the hydration housing vessel and configured for gas-liquid contact;
a solution distribution system coupled to the hydration housing vessel and comprising a pump configured for flowing the hydration solution over at least a portion of the contact zone;
a hydration solution collection basin coupled to the hydration housing vessel and configured to receive the hydration solution leaving the contact zone;
a drift elimination section coupled to the hydration housing vessel and configured to prevent hydration solution from leaving with a humidified gas stream;
at least one outlet coupled to the hydration housing vessel and configured to dispense the humidified gas stream;
at least one outlet port coupled to the hydration housing vessel and configured to discharge at least a portion of the hydration solution;
a CO2 capture packing section;
a capture solution drift elimination section; and
an open plenum at least partially delimited by the capture solution drift elimination section, the at least one gas feed stream configured to flow sequentially through the gas inlet section, the contact zone, the drift elimination section, the CO2 capture packing section, the capture solution drift elimination section and into the open plenum.
