Predictive Emissions Monitoring System (PEMS) for industrial and aeroderivative gas turbines

With growing focus on decarbonization and clean energy, it is essential for plant operators to monitor and record emissions data to demonstrate regulatory compliance. Monitoring options range from temporary expert-led setups to permanent systems. Due to frequent reporting requirements, many operators are opting for cost-effective, permanent solutions. Siemens Energy is offering the Predictive Emissions Monitoring System as solution for emissions reporting requirements.

Predictive Emissions Monitoring System (PEMS) is the next level of emission monitoring in a cost effective and regulatory compliant manner. Compared to the traditional Continuous Emissions Monitoring System (CEMS), PEMS do not use hardware-based sensors to measure emissions. PEMS is a digital solution, taking engine operational data and feeding through a unique set of algorithms, determining the emissions signature of the engine. The predictive emission monitoring system is applicable for all industrial and aeroderivative gas turbines.

PEMS provides an unique OEM experience, allowing operators to significantly reduce the CAPEX and OPEX of emissions measurement activities. PEMS can be operated as redundant systems next to CEMS or as standalone certified systems without CEMS.

PEMS evaluates emissions in accordance with international standards like US EPA Part 40 CFR 60 PS 16, and CEN TS 17198.
