Predictive Emission Monitoring System (PEMS)

Significant reduction in operational and maintenance costs

Providing a view of your equipment to review & reduce emissions

“PEMS are the next level of emission monitoring in a cost effective and regulatory compliant manner. Compared to the traditional CEMS, PEMS do not use hardware-based sensors to measure emissions, but instead use unique algorithms to determine the emissions signature of an engine, based on the input parameters.

The digital models include Siemens Energy’s 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."

Digital form called PEMS (Predictive Emissions Monitoring System)

The PEMS product is a digital solution, taking engine operational data and feeding through a unique set of algorithms, determining the emissions signature of the engine.

Prediction of exhaust emissions using system internal engine parameters (no extra hardware is needed on site).
Our PEMS uses unique knowledge of the gas turbine product the algorithm is used for continous learning based on the existing historical data.
PEMS is evaluationg emissions in accordance with international standards e.g. EPA 40 CFR/ EU LCP/MCP, CEN TS 17198.

Fleet Applicability

Greenfield and brownfield projects
Customers who operate our gas turbines.
Customers or operators within the Power Generation and Oil and Gas industries who are looking to monitor and understand their emissions footprint (NO_x, CO and CO₂).
Customers or operators who want more insight into emissions levels who can then make more informed decisions about plant operations, with the potential to modify their operating profile to reduce emissions and fuel and maintenance costs.
Customers who are looking for a lower cost alternative to Continuous Emissions Monitoring System (CEMS), which requires significant CAPEX and OPEX costs.

Support Services & Implementation

Embedded Controls Solution

DCS-embedded: Algorithm embedded into the main turbine control system software e.g. PCS7, Alan Bradley™ or Omnivise T3000.
Emission data will be displayed in high resolution real-time directly on the Human-Machine-Interface (HMI); minor activities on site required.
Edge-based: Algorithm embedded in the on-site data collector (Omnivise Edge) with dashboard access via browser.

Physical version called CEMS (Continuous Emissions Monitoring System)

Cloud Based Solution

With algorithms embedded within our known cloud platforms ‘Omnivise Cloud Platform’, data received via remote connection.
Integrated within our known digital frontend platforms ‘MyHealth’ or ‘Omnivise’; therefore, providing data and the ability to analyze data straight to your chosen device.

Benefits

Emissions calculations without additional instrumentation requirement at site.

Significant reduction in operational and maintenance costs compared to a traditional hardware-based based emissions monitoring system. The lower CAPEX and OPEX, estimated 50-80% compared to CEMS lifecycle cost.

Ultimate confidence in the PEMS model using thermodynamic knowledge of the engine, as well as verification of several years of reliable factory test data on every unit shipped, as well as access our fleet and field operating experience and data.

PEMS do not require trained and skilled operators.

It is possible for our PEMS solution to run in highly contaminated flue gases and harsh environmental conditions, since the solution is completely digitalized in nature, therefore negating the requirement for costly SIL/ATEX rated hardware.

PEMS can be used by the customer as well as Siemens Energy in potentially identifying engine performance issues using the associated PEMS data for fault finding and analysis.
