AVANT energy & solutions provide its services for PEMS Modeling. PEMS exploits advanced mathematical models, which use process parameters (e.g. pressure, temperatures, flow, etc.) as input variables in order to estimate the most common air pollutant emissions (e.g. NOx, SO2, CO, CO2, etc.) using regression model which is trained over experiment data diligently designed for the purpose.

Advantages

• Model-based emission monitoring provides a number of unique features and advantages:
• PEMS are compliant and accepted by international environmental regulations and standards.
• Increase emission data availability up to 99.5% 
• PEMS can be interfaced directly with plant control systems without the installation of any additional components  
• PEMS do not require the complex and difficult-to-maintain infrastructure in order to collect the sample at stack, handle and process  
• PEMS are a non-invasive technology that can be easily integrated at site in a standard server PC, optimizing overall footprint and space 
• Quick and easy implementation and integration at site with minimal disturbance to plant operations. 
• They provide an overview on the process, highlighting anomalies and providing a preliminary evaluation of emission excess
