Description:
Fossil Energy Research Corporation proposes the devel- opment of a novel duct injection process for simultaneous removal of SO2 and NOx from coal-fired power plant flue gases. In this process, a mixture of lime and a proprietary sorbent is injected either dry or in the form of a slurry into the flue gas duct between the air preheated and particulate collection device. Lime removes SO2 and the proprietary sorbent removes NOx from the flue gas. The NOx separated from the flue gas is fed back to the boiler where it is reduced to N2 and H2O. The unused lime and most of the NOx sorbent are recovered and recycled. The waste product of the process is a solid residue which contains fly ash and sulfates of calcium. A rough cost estimate showed that the proposed duct injection process has a potential cost advan- tage of 60% - 70% when compared to other combined SO2 and NOx removal processes.
