The NOXSO process is a dry, post-combustion flue gas treatment technology which uses a regenerable sorbent to simultaneously adsorb sulfur dioxide (SO{sub 2}) and nitrogen oxides (NO{sub x}) from the flue gas of a coal-fired utility boiler. In the process, the SO{sub 2} is converted to a sulfur by-product and the NO{sub x} is converted to nitrogen and oxygen. It is predicted that the process can economically remove 90% of the acid rain precursor gases from the flue gas stream in a retrofit or new facility. The objective of the NOXSO Demonstration Project is to design, construct, and operate a flue gas treatment system utilizing the NOXSO process. The effectiveness of the process will be demonstrated by achieving significant reductions in emissions of sulfur and nitrogen oxides. In addition, sufficient operating data will be obtained to confirm the process economics and provide a basis to guarantee performance on a commercial scale. The project is presently in the project definition and preliminary design phase. Data obtained during pilot plant testing which was completed on July 30, 1993 is being incorporated in the design of the commercial size plant. A suitable host site to demonstrate the NOXSO process on a commercial scale is presently being sought. Preliminary engineering activities involved evaluating various design options for the major process vessels with the principal focus being on the sorbent heater vessel, which is operated at the highest temperature. Additionally, the impact of the NOXSO system on power plant particulate emissions and opacity was estimated. It is predicted that particulate emissions will decrease slightly while opacity will increase slightly. Neither change will be significant enough to have an impact on emissions compliance. Advertised performance of the proposed adsorber separator is being verified by laboratory testing. Process studies activities included POC equipment inspection and materials evaluations.
