AbstractThis SBIR Phase I program aimes to demonstrate the feassibility of an innovative multi-polutant removal technology for the flue gas purification of small industrial boilers. Compared to the conventional flue gas purification processes, the proposed technology is more suitable for the small industrial boiler applications, and displays several advantages, such as low installation and operation cost, as well as high removal efficiency. This noivel technology can simultaneously remove particuate matters smaller than 10 microns (PM10), sulfur dioxide (SO2), hitrogen oxides (NOx) 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 and surface-filtered by sorbent Unlike the conventional adsorption process, the proposed innovaton does not require any sorbent generation steps, which makes the system much simple and low-cost. During the program, by investigating the ozone oxidation and modifiying the catalytic sorbent material, testing material's PM10, SO2, NOx and HG removal perforance, and long-term run efficiency, the feasibility of the proposed technology will be demonstrated. If successful, the proposed technology can provide a retrofit and inexpensive PM10, SO2, NOx and HG removal system for small industrial boiler flue gas purification It also has the potential for large scale utility boiler applications
