The report describes a brief test series that demonstrates that both Drierite and molecular sieve sorbents can cause incorrect NO results if SO2 is present. It was noted that the standard analytical system used for measuring NO emissions gave incorrect NO emmissions in the presence of SO2. The problem was traced to the dry sorbents used to remove water vapor prior to the NO analysis. Further testing revealed that the materials can simultaneously remove both NO and SO2, even in low concentrations. Although more work is needed to define the actual fate of these species, it appears that this might offer a possible NOx/SOx control technique since the data indicate that the sorbent effect is thermally regenerable.
