PEMS is a software-based system that calculates and predicts emissions from combustion processes and engines based on operational data – with accuracy on par with or better than continuous physical measurement systems.
Instead of expensive, maintenance-intensive physical analyzers, PEMS uses operational data that the engine is already logging – load, pressure, temperature, RPM, fuel quality – and calculates emissions in real-time using neural networks.
PEMS is designed as Best Available Technique (BAT) under the EU's IPPC directive and is in operation at several hundred emission sources globally, primarily in the USA and Europe.
Empirical data model based on neural networks establishes the relationship between operating parameters and emissions
Simultaneous recordings of operating data (pressure, temperature, load, rpm, fuel quality) and accredited exhaust measurements establish the training dataset for the neural network model.
Ecoxy builds the empirical model using advanced neural networks. The model captures non-linear relationships between operating parameters and emissions.
The model's accuracy is documented and verified against actual measurements. The system meets the accuracy requirements for continuous emissions monitoring systems (CEMS).
After installation, the system provides continuous emission data based on operating parameters. Operators receive alerts for abnormal operating conditions and invalid measurement data.
No costly physical analyzers require calibration and maintenance. PEMS operates on existing operational infrastructure.
The system withstands measurement errors through data validation. Invalid measurements are replaced with calculated values, and the operator is automatically notified.
Ongoing overview of emission levels without the need for frequent manual campaign measurements. Ideal for facilities with varying loads.
PEMS is approved as BAT under the IPPC directive and is accepted as documentation basis in an increasing number of regulations.
The combustion process must use defined fuel types (liquid, gas, or solid) for the model to be valid.
Sufficient instrumentation is necessary, but standard equipment for operational monitoring is usually adequate.
Accredited exhaust measurements are conducted simultaneously with operating data during model establishment. Ecoxy provides this as part of the PEMS project.
The model should be verified after maintenance that affects the combustion process or by regulatory requirement.
