摘要

The NOXSO Process is a dry, regenerable system capable of removing both SO sub 2 and NO/sub x/ from flue gas generated by coal-fired utility boilers. Adsorption is accomplished at the normal post-airheater flue gas temperatures of around 120 exp 0 C, and SO sub 2 and NO/sub x/ are simultaneously removed from the flue gas in a single step. Regeneration of the sorbent is accomplished at elevated temperature (greater than or equal to 550 exp 0 C) using any of a number of reducing agents, e.g. hydrogen sulfide, hydrogen, carbon monoxide, methane, etc. Hydrogen sulfide was used in all the tests reported here. On regeneration, the compounds formed by the adsorption of SO sub 2 and NO/sub x/ are reduced to elemental sulfur and nitrogen. The NOXSO test program has the ultimate goal of determining the commercial potential of the NOXSO process. The specific test program conducted involves three basic tasks: fundamental studies to determine the process chemistry, kinetics and the influence of various parameters; sorbent studies to determine sorbent properties that contribute to low attrition and efficient sorption; and process studies that determine the physical size and the costs of a commercial facility. The report is organized accordingly. Chapter 2 is an Executive Summary of the entire report. Chapter 3 describes in detail the test facility, equipment and test procedures. Chapter 4 provides a detailed discussion of the process chemistry. Chapter 5 presents the kinetic model and supporting data. Chapter 6 gives the sorbent attrition data and ideas to explain the excellent performance of the NOXSO sorbent. Chapter 7 presents design guidelines for critical NOXSO process equipment. Chapter 8 discusses the economic study conducted by Science Applications, Inc. and the Appendix reproduces the SAI report. 5 references, 50 figures, 22 tables. (ERA citation 09:030171)
