1. A system for removing contaminants from an industrial stream of exhaust gas, the system comprising: a first misting stage configured to receive the stream of exhaust gas and contact the stream of exhaust gas with mist of water and hydrogen peroxide (H2O2) to create a first liquid comprising first liquid acids, the first liquid acids comprising nitric acid (HNO3) and carbonic acid (H2CO3);a first condensing medium configured to condense the first liquid acids from the stream of exhaust gas comprising HNO3 and H2CO3 and to collect on a surface of the first condensing medium a first residual liquid mixture of HNO3 and H2CO3;a second misting stage configured to receive the stream of exhaust gas and contact the stream of exhaust gas with water mist to create a second liquid comprising second liquid acids, the second liquid acids comprising nitric acid (HNO3) and carbonic acid (H2CO3);a second condensing medium configured to condense the second liquid acids from the stream of exhaust gas comprising HNO3 and H2CO3 and to collect on a surface of the second condensing medium a second residual liquid mixture of HNO3 and H2CO3;a third misting stage configured to receive the stream of exhaust gas and contact the stream of exhaust gas with a mixture of chilled water and amine (RNH2) to form a liquid solution of carbon dioxide (CO2);a third condensing medium configured to condense the liquid solution of CO2 and to collect on a surface of the third condensing medium a third residual liquid mixture of HNO3, H2CO3, and CO2; andan activated carbon stage configured to receive the stream of exhaust gas and to contact the stream of exhaust gas with granular activated carbon to further remove trace contaminants from the exhaust gas stream. 2. The system of claim 1, wherein the exhaust gas is created by combustion of coal. 3. The system of claim 1, wherein the exhaust gas is created by combustion of natural gas. 4. The system of claim 2, further comprising and located upstream from the first misting stage: a boiler configured to receive the exhaust gas and to remove heat from the exhaust gas;an electrostatic precipitator configured to receive the exhaust gas and remove particulate matter from the exhaust gas;an ozone aspirator, wherein the ozone aspirator is configured to receive the stream of exhaust gas from the boiler and contact the stream of exhaust gas with ozone to convert nitrate (NO) within the exhaust gas to nitrogen dioxide (NO2) thereby forming a stream of exhaust gas comprising NO2 and residual NO; andan economizer configured to recover heat from the stream of exhaust gas. 5. The system of claim 1, wherein the activated carbon stage comprises: granular activated carbon having an average size that is greater than 0.25 mm. 6. The system of claim 1 further comprising a fan configured to direct a clean exhaust gas stream out of the system. 7. The system of claim 1 further comprising a wastewater facility configured to receive a water film comprising the first residual liquid mixture and the second residual liquid mixture. 8. The system of claim 1 further comprising an exhaust stack configured to receive at least one of the first, second, and third residual liquid mixtures. 9. The system of claim 1, wherein the first condensing medium comprises a coating of one selected from a group consisting of Teflon and critical polyvinal chloride (CPVC). 10. The system of claim 1, wherein the second condensing medium comprises a coating of one selected from a group consisting of Teflon and critical polyvinyl chloride (CPVC). 11. The system of claim 1, wherein the activated carbon stage comprises a hollow frame configured to receive and hold activated carbon, wherein the hollow frame comprises a plurality of V-shaped members. 12. The system of claim 11, wherein the hollow frame comprises a wire mesh attached to a front side and a back side of the hollow frame. 13. The system of claim 11, wherein the plurality of V-shaped members form a hollow frame having a W-shaped cross-section. 14. The system of claim 12, wherein the activated carbon stage comprises a top opening for loading activated carbon and a bottom opening for unloading de-activated carbon. 15. The system of claim 14, wherein the activated carbon stage comprises sealed access doors on the top opening of the activated carbon stage and sealed access doors on the bottom opening of the activated carbon stage.
