Watch our video about sulfur dioxide monitoring sulfuric acid production plants. Process monitoring in this application requires reliable detection of gases such as sulfur dioxide (SO₂) in the gas phase.
This can be particularly challenging due to high SO₂ concentrations, elevated temperatures, and high pressure conditions.
Measurements may be needed at different points in the process where concentrations vary from a few mg/m³ to several percent by volume.
Many conventional monitoring systems struggle under these conditions and often require frequent maintenance, sometimes even daily.
In contrast, OPSIS monitoring systems are designed to operate effectively in such harsh environments with minimal maintenance requirements and can be used across multiple stages of sulfuric acid production.
