Sulfur Oxides Low VElocity filter (SOLVE)
The SOLVE filter is a special acid mist filter with an injection of hydrogen peroxide solution that oxidizes residual SO2 to SO3. The SO3 then immediately reacts with water vapor in the gas to form sulfuric acid that is captured in the low-velocity mist filter.
SOLVE filters are supplied only in connection with WSA or SNOX™ plant technology.
