  • Process for removing NOx from nitrosylsulphuric acid
    Patent number: 6238639
    Abstract: Nitrosylsulphuric acid is mixed in a mixing reactor with sulphuric acid saturated with SO2. The acid mixture is led into a saturating reactor into the bottom region of which water and an SO2-containing gas are introduced. The gas partially serves as stripping gas inside the saturating reactor. SO2-saturated, Nox-free sulphuric acid with 5 to 60 wt % H2SO4 is removed from the bottom region of the saturating reactor and part thereof is mixed with nitrosylsulphuric acid in the mixing reactor.
