METHOD AND SYSTEM FOR REMOVING POLLUTANTS AND GREENHOUSE GASES FROM A FLUE GAS

摘要

A system and method for removing pollutants and greenhouse gases SO2, NO2, and CO2 from a flue gas stream, includes: a) contacting natural seawater with a flue gas for a given period of time to remove SO2 from the flue gas; b) contacting treated alkaline water to the flue gas to remove CO2 and NOx from the flue gas and generate oxygen and carbon particles; and c) collecting or emitting the flue gas after step b). The method and the system of the invention are significantly more economical and convenient and do not cause harm to the environments. The invention also exhibits a novel and unique feature that elemental carbon and oxygen are generated as final products and can be recovered as an energy source.
