The focus of the R&D project is on the development of a cost-effective, industrially suitable, real-time measurement system for the precise and continuous determination of the acid dew point in the exhaust gas flow. By avoiding corrosion (caused by acid build-up), improvements in plant safety and maintenance can be achieved. At the same time, an optimisation of the use of energy sources and a significant reduction of CO2 emissions can be achieved through an exact, sensor-controlled flue gas process control and the resulting reduction in the temperature of the flue gas flow.
If the acid dew point is recorded, the flue gas temperature can be lowered to a temperature only a few Kelvin above the acid dew point temperature. In this way, the use of fuel material to maintain the optimal flue gas temperature can be reduced, CO2 emissions can be lowered and industrial plants can be operated in a gentle manner. The online control of such waste gas flows contributes to improving the industrial CO2 balance, which is becoming increasingly important for plant and process operators in view of climate protection targets.
