Data integrity and accuracy to avoid fines and penalties

Predictive Emission Monitoring Systems (CEMS)

What is Predictive Emission Monitoring Systems (AML-PEMS)

Predictive Emission Monitoring System (PEMS) is an alternative approach to Continuous Emission Monitoring System (CEMS). Both systems are solutions mandated by environmental agencies to meet air quality permit requirements such as MCERTS, TV, and US EPE Part 60 & 75. PEMS is a software-based solution able to deliver reliable real-time emission estimations based on historical and process data, exploiting advanced mathematical or statistical models, which use process parameters (e.g., pressure, temperatures, flow, etc.). as input variables to estimate the most common air pollutant emissions (NOx, SO2, CO, CO2, etc.).   

Predictive Emission Monitoring System (PEMS) provides accurate emission monitoring, reducing the capital investment and ongoing operating costs due to maintenance activities and spare parts, minimizing the interferences with plant operations. AML-PEMS allows operators and plant owners better control on costs, neglecting unexpected expenses due to unpredicted issues in the conventional hardware analyzers.

Why should you select AML-PEMS?

AML-PEMS technology provides several inherent advantages compared with traditional hardware-based analyzers. The AML-PEMS solution is very cost-effective both in terms of initial investment and lifecycle costs. Depending on the application, local regulation, and site constraints, it can be used as a conventional hardware backup analyzer and the only emission monitoring system. 

More and more complex large projects will include traditional CEMS side-by-side with PEMS for selected units. One of the main interests of plant operators is to increase the availability of their Environmental Monitoring System (EMS). With the adoption of AML-PEMS as a backup of a traditional hardware analyzer, EMS uptime can be increased up to 99.5%. 

Decarbonization, emissions

Enable Improvement With AML-PEMS

Ease of Use​

Reduce the number of time operators spend using the system and get their work done quickly and effectively.


Eliminate single points of failure with a distributed architecture.

Predictive Maintenance

Reduce costly repairs by detecting problems through calibration control, tracking, and reporting.

Scalability and Expandability

Transmitting all the analog and digital channels over the TCP/IP network significantly increases scalability and expandability.


Save money on long-term maintenance; no spare parts needed, quick implementation

Remote Access and Monitoring

A standardized way to connect people, processes, and technology with a consistent interface.

As environmental regulations become more stringent, companies and municipalities are facing immense investment and development challenges.
