Description:
This novel technology can simultaneously remove particulate matter smaller than 10 microns (PM10), sulfur dioxide (SO2), nitrogen oxides (NO X), and mercury (Hg) from the flue gases of oil and coal-fired small industrial boilers. The technology uses ozone to oxidize NO into high oxides, and applies an innovative catalytic sorbent material to convert high nitrogen oxides and SO2 into nitric acid and sulfur acid simultaneously in the presence of oxygen and water vapor. In the process, mercury can be chemically fixed in the sorbent, and fine particles can be surface-filtered by the sorbent. Unlike the conventional adsorption process, the proposed innovation does not require any sorbent-generation steps, which makes the system much simpler and low cost. Sorbent Technologies, Inc., will demonstrate the proposed technology by investigating the ozone oxidation and modifying the catalytic sorbent material; testing the material’s PM10, SO2, NO X, and Hg removal performance; and determining the long-term run efficiency.
If successful, the proposed technology can provide a retrofit and inexpensive PM10, SO2, NO X, and Hg removal system for small industrial boiler flue gas purification. It also has the potential for large-scale utility boiler applications.
