Optimized real-time flue gas treatment

Our solution precisely adjusts reagent injections:

Continuous analysis of pollutant concentrations and combustion dynamics
Prediction of flue gas quality at the furnace outlet, even without a physical sensor
Precise adjustment of reagent injections (urea, bicarbonate, lime, activated carbon, etc.)

Objective:
Reduce emissions, decrease reagent consumption, and comply with discharge limits.

Reducing reagent injection

Purecontrol finely regulates reagent inputs based on the actual quality of the fumes and their predicted evolution. Thanks to virtual sensors, regulation remains optimal even without analyzers, eliminating overdoses.
Thanks to virtual sensors (digital twin), the regulation remains optimal even without analyzers, avoiding unnecessary overdoses.

Reduced consumption thanks to precise injection control

Compliance with discharge thresholds

Based on continuous predictions of pollutant concentrations, the solution enables more stable control, limiting regulatory exceedances while avoiding overdosing.
Purecontrol thus regulates injection instructions in real time in a more precise and stable manner, which allows better compliance with regulatory ELVs while avoiding overdoses.

Fewer exceedances, without overdosing of reagents

Advanced supervision and performance monitoring

Purecontrol continuously monitors reagent injections and pollutant concentrations. The platform detects overconsumption, anticipates emission deviations, and displays upcoming injection instructions to ensure precise, compliant regulation over time.
The platform detects overconsumption, anticipates emission drifts and visualizes future injection instructions, to guarantee fine and compliant regulation over time.

Fewer alarms, fewer emergency interventions

Intelligent control of reagent injection

By continuously analyzing the quality of the flue gas, Purecontrol reconstructs pollutant concentrations using virtual sensors. Predictive models anticipate the trajectory of NOx, NH₃, HCl, or SO₂ based on combustion and operating conditions.
Predictive models anticipate the trajectory of NOx, NH3, HCl or SO₂ pollutants according to combustion and operating conditions.
Purecontrol automatically adjusts reagent injections. Optimized instructions from the digital twin limit consumption while keeping emissions within standards, regardless of load or fuel variations.

Optimizing waste-to-energy plants: 3 levers for improving energy and environmental performance

Waste-to-energy plant operators have to juggle sometimes conflicting requirements: ensuring stable combustion despite heterogeneous fuel, meeting the needs of the heating network, while remaining compliant with environmental regulations. All this with limited human resources, facilities already optimized by conventional automation systems, and increasing pressure on operating costs.

Discover three concrete levers for improving their overall performance.
