Predictive Emission Monitoring Systems (PEMS)

By Gregorio Ciarlo and Federico Callero, ABB S.p.A.

In the process industries, legal requirements regulate the continuous acquisition of emission data to monitor and control pollutants released into the atmosphere. Data verifies that plant emissions do not exceed law-enforced thresholds. From a plant owner's perspective, it's important that efficient and reliable tools for acquiring emission data are available. Typical plant continuous emission monitoring systems (CEMS) are essentially hardware-based.

Software-based predictive emission monitoring systems (PEMS) represent an alternative, accepted by several environmental regulations, for monitoring and recording air pollutant emissions. Read the full article to learn more.
