Air contactor

An air contactor comprising:

• an airflow generator operable to produce an airflow;
• an air pollutant capture system comprising:
• an air pollutant capture apparatus to transfer an air pollutant from the airflow and to a fluid;
• a fluid regeneration apparatus configured to utilize heat from a heat source to remove the air pollutant from the fluid;
• and
• a thermal energy storage operable to either receive heat from the fluid or provide heat to the fluid regeneration apparatus;
• the air pollutant capture system having:
• a regeneration and charging mode wherein the fluid regeneration apparatus receives heat from the heat source, the fluid regeneration apparatus removes the air pollutant from the fluid, and the thermal energy storage receives heat from the fluid;
• and
• a regeneration and discharging mode wherein the fluid regeneration apparatus receives heat from the thermal energy storage and the fluid regeneration apparatus removes the air pollutant from the fluid;
• and
• a controller operatively connected to the air pollutant capture system, the controller configured to operate the air pollutant capture system in the regeneration and discharging mode in response to a determination of the air pollutant capture system in the regeneration and discharging mode satisfying an operating criterion.
