The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.

Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective Catalytic Reduction unit (SCR), which deploys ammonia gas NH3 to limit emissions of NO and NO2. A modern nitric acid plant needs to monitor the emissions of these gases.
