| Abstract: | Abstract Interpretation of flue gas acid dewpoints in terms of sulfuric acid concentrations has relied heavily upon Mullers1 work. A more recent work by additional authors indicates disagreement with Muller's curves. This work involves the study of the acid dewpoint-acid concentration relationship using a commercially available acid dewpoint meter. The study involves generating a steady-state, high temperature, sulfuric acid gas stream using a newly designed acid generation system. By using an absorption reference method, dewpoint as a function of acid concentration and moisture are compared with previous authors. The relationship established is then used along with the previous works to interpret some actual flue gas dewpoints to simultaneous flue gas acid measurements. |
