CEMS Systems Predictive Emissions Monitoring (PEMS)
for 40 CFR Part 75 Subpart E and 40 CFR Part 60 Appendix B Sources

PEMS Pro-Logix 60 is a PLC-based emissions monitoring and reporting software for sources qualifying under 40 CFR 60 Appendix B (boilers) and 40 CFR Part 75 Subpart E. Multiple sources can be monitored with data and controls access for local, network and remote operators.

Full Featured Predictive Emissions Monitoring System
PEMS Pro-Logix 60™ is a full-featured, predictive emissions monitoring software for qualified sources under the EPA PS-16 audit standards for compliance with 40 CFR Part 75 Subpart E and 40 CFR Part 60 Appendix B regulations for monitoring nitrogen oxides and oxygen at industrial sources. PEMS Pro-Logix 60™ uses a statistical hybrid model to provide real-time emissions predictions from a wide range of operating input parameters with CEMS-level accuracy and reliability. PEMS Pro-Logix 60™ calculates criteria pollutant emissions with CEMS-level accuracy, thereby lowering operating costs and increasing reliability. Deliver real time results over your Ethernet/IP networks for the highest system visibility available.

CEMS-Level Data Accuracy
The PEMS model will be able to accurately predict NOx, O2, and CO2 for emissions across all loads and operating scenarios with as few as three sensor inputs or with as many as fifteen sensor inputs. A fourth order polynomial model will be created for each sensor input. In this way, the accuracy of the predictive model can be evaluated for each individual input sensor thereby establishing it’s predictive relative accuracy compared to the other sensor inputs. In addition to developing the PEMS model, AMP-Cherokee will also create a sensor input validation model which will be able confirm the validity of a given sensor input based on it’s relative value in relation to other sensor input values.

After the predictive emissions model and the sensor input validation model have been completed for each boiler, AMP-Cherokee will conduct a bench trial in which historical data is used to evaluate the PEMS model. In this way, engineers can make final adjustments to the PEMS model prior to deployment thereby increasing it’s accuracy.

Data Redundancy & Auto Backfill
With DAS Pro-Logix 60™, data redundancy is provided at the PLC and polling computer prior to distribution to Ethernet/IP-based networks. Any data transfers that are interrupted by network disconnections are automatically restored to all servers.

Easy to Use. High Performance. High Reliability.
PEMS Pro-Logix 60 combines its comprehensive dialogue screens and monitoring analysis tools into an easy to use interface. PEMS Pro-Logix 60 offers all the monitoring capability needed to perform accurate data collection and real-tme analysis. PEMS Pro-Logix 60 runs efficiently providing constant visibility via real-time data, trending and customizable reporting. PEMS Interface Customization One of the unique features of PEMS Pro-Logix 60 is its programming flexibility.

Open Architecture. Allen-Bradley PLCs. HMI>Network Interface.
Our open architecture PEMS ProLogix 60™ data acquisition and reporting software, through its HMI>Network Interface™ and Allen-Bradley® PLC platform, provides network connectivity and remote operation.

Real Time & Historical Displays. PEMS Reporting Suite.
PEMS Pro-Logix 60™ has customizable real time and historical display graphs to allow monitoring of emissions and process parameters. The PEMS Pro- Logix 60™ Reporting Suite provides Part 60 compliant reporting, including daily calibrations, emissions reporting, and rolling averages.

PEMS Remote Operation. Alarms and Notification.
PEMS Pro-Logix 60™ controls operations and monitors system health status. User-configurable email alarms - critical and noncritical - can be configured across your monitoring network. Remote access provides administration level operation controls and troubleshooting tools to locate PEMS faults.

Process Input Sensor Validation & Error Correction
From source data collected during process characterization, the PEMS Pro-Logix 60™ provides dynamic process sensor validation and error correction, along with data acquisition functions such as startup, shutdown, and other historical events.
