Emission Monitoring SystemsWhat is PEMS ?
PEMS - Predictive Emission Monitoring Systems A software based technology compared to CEMS
What is PEMS ?
gy p
PEMS provide “emission estimation” based on sophisticated Models
Using mathematical and/or statistical techniquesUsing mathematical and/or statistical techniques
Models are able to exploit the inherent correlation
Between process variables (flow, temperature and pressure)Between process variables (flow, temperature and pressure)
and emission properties (NOx, SO2, CO, CO2)
Correlation of values are assessed and evaluated through CEMS g
Emission Data collected first from existing analyzers
Acquisition compaign of Emission values
Process Data from plant Control System (DCS, PLC)
