This paper gives results of an evaluation of calcium sorbents for acid gas emission control for effectiveness in removing SO{sub 2}/HCl and SO{sub 2}/NOx from simulated incinerator and boiler flue gases which is used in municipal solid waste disposal. All tests were conducted in a bench-scale fixed-bed reactor simulating fabric filter conditions in an acid gas removal process. Reagent grade Ca(OH){sub 2} was used to establish baseline sorbent performance. Several additives were subsequently tested to determine optimum sorbent combinations for SO{sub 2}/NO control. As with SO{sub 2}/HCl, calcium silicate has been shown to be superior for SO{sub 2}/NO capture. Some implications for larger-scale process configurations and sorbent selection for HCl/SO{sub 2}/NO control are discussed.
