Abstract
The invention relates to an apparatus and method for reducing contaminants from industrial processes. More particularly, the invention is directed to a method of sequestering pollutants from flue gases in operational plants. The method includes sequestering contaminants from a point source by reacting an alkaline material with a flue gas containing contaminants to be sequestered, wherein the reaction has a rapid mass transfer rate to sequester at least a portion of the contaminants.
Claims22
A method of simultaneously sequestering and storing Hg0, SO2 (g) and CO2 (g) from flue gas from a point source, the method consisting essentially of the steps of:
- reacting an alkaline material with a flue gas from a point source, the flue gas containing Hg0, SO2 (g) and CO2 (g) to simultaneously sequester the Hg0, SO2 (g) and CO2 (g),
- wherein the sequestered Hg0, SO2 (g) and CO2 (g) are mineralized and stored in the alkaline material.
A method of simultaneously sequestering and storing CO2 (g), SO2 (g) and Hg0, contaminants from a flue gas from a point source of a coal fired plant, consisting essentially of the the steps of:
- reacting an alkaline material with a flue gas of the coal fired plant from a point source,
- the flue gas containing the CO2 (g), SO2 (g) and Hg0,contaminants to be sequestered and stored,
- wherein the reaction has a rapid mass transfer rate to sequester at least a portion of the CO2 (g), and
- wherein the sequestered CO2 (g), SO2 (g) and Hg0,are stored in a reacted alkaline material.
A method of simultaneously sequestering and storing SO2 (g) and Hg0, from a flue gas of a coal fired plant from a point source, consisting essentially of the steps of:
- reacting an alkaline material with a flue gas of a coal fired plant from a point source, the flue gas containing SO2 (g) and Hg0, simultaneously sequester the SO2 (g) and Hg0, and
- wherein the SO2 (g) and Hg0, are stored in the reacted alkaline material.
