Approaches for removing co2, so2 and other gaseous contaminates from gas emissions

A method for removing CO2 from a flue gas emission of a power plant, the method comprising:

• providing a supply of an ionic liquid;
• electrospraying fine liquid droplets of the ionic liquid into the flue gas emission,
• wherein CO2 from the flue gas emission is absorbed in the ionic liquid;
• wherein electrospraying the ionic liquid into the flue gas emission comprises ultrasound agitation of the ionic liquid;
• capturing the ionic liquid having CO2 absorbed therein on a counter electrode to remove CO2 from the flue gas emission;
• and
• venting the flue gas emission having CO2 removed therefrom.

A method for removing at least partially one or more gaseous contaminants from a flue gas emission of a power plant, the method comprising:

• providing a supply of an ionic liquid, wherein a gaseous contaminant is absorbable in the ionic liquid;
• electrospraying fine liquid droplets of the ionic liquid into the flue gas emission, wherein the gaseous contaminant from the flue gas emission is absorbed in the ionic liquid;
• wherein capturing the ionic liquid having the gaseous contaminant absorbed therein on a counter electrode to remove the gaseous contaminant from the flue gas emission;
• venting the flue gas emission having the gaseous contaminant removed therefrom;
• and
• recycling the ionic liquid having the gaseous contaminant removed therefrom into the supply of ionic liquid.
