Commercial demonstration of the NOXSO SO{sub 2}/NO{sub x} removal flue gas cleanup system. Quarterly technical progress report No. 11, September 1--November 30, 1993
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 reduced to sulfur by-product and the NO{sub x} is reduced 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 studies provided information to decide on the basic plant arrangement. A scaled up POC design was selected as the general arrangement of choice based on a cost versus technical risk assessment. The first step in developing an adsorber computer simulation was completed. Several processes for producing liquid SO{sub 2} from the regenerator offgas were developed and evaluated. It was concluded that the Claus and burn process which involves making elemental sulfur as an intermediate product was the best choice. The NOXSO process computer simulation was updated to include semi-plug solids flow through the fluidized beds of the sorbent heater and cooler. Heat loss calculations were also added.
