Claim 10:
11. A method comprising:
transmitting an emission stream from a semiconductor manufacturing process through an abatement apparatus configured to abate the emission stream therein;
transmitting the emission stream from the abatement apparatus through a condenser configured to reduce water vapor of the emission stream and yield an effluent;
transmitting the effluent from the condenser through a reduction tower, wherein the reduction tower comprises a reduction chamber having an inlet coupled to an outlet of the condenser, and a nozzle disposed within the reduction chamber; and
dispensing a solution through the nozzle into the reduction chamber,
wherein the solution catalyzes a chemical reaction to absorb a pollutant from the effluent and yield an exhaust substantially free of the pollutant.
