A Better Approach to Emissions Compliance
Emissions compliance can be complex and challenging, requiring hundreds of data points from dozens of sources, painstaking calculations, and detailed documentation for state and federal regulators. Violations can result in fines, new requirements, audits or consent decrees, and negative publicity. EXELE empowers companies to overcome these challenges with CEMS-based / Environmental DAS / RTU systems to make compliance simple, streamlined, and stress-free.
Real-time monitoring. Automated calculations. Error-free reporting.
PI-DAS is an all-in-one solution built directly onto industry-leading data historians like AVEVA PI, empowering customers to manage emissions compliance more effectively with:
- Real-time data acquisition
- Robust data validation
- Seamless data aggregation
- Integrated reporting
Comprehensive, integrated operational and calculated environmental data
With PI-DAS, businesses can leverage accurate, real-time data and robust customization capabilities to:
- Automate routine tasks
- Streamline reporting
- Complete daily activities efficiently and error-free
- Simplify audits with full visibility and transparency
- Enjoy responsive support from dedicated experts
Save time and effort, reduce risk and expense, and enjoy real peace of mind with PI-DAS
Key Features
- Versatile technology: Leverage the AVEVA PI System or your preferred data historian; integrate readily with existing software and hardware at any scale.
- User-friendly configuration: Easily configure for site-specific permit conditions, instrumentation, business processes, and applicable regulations.
- Automated acquisition: Monitor data and analyzer status from the field; capture calibration drift checks, maintenance status, fault signals, and overrides.
- Data validation: Automatically validate data every hour via transparent, real-time calculations, retrospective recalculation, and calibration drift correction to produce rollups and aggregated totals.
- Evaluation and notification: Immediate notification of invalid data, analyzer faults, and out-of-control events; integrated tracking of downtime, exceedance, and reason/action codes.
- Advanced automation: Compliance averaging using quality-assured, validated data; automated preparation of calibration, EEMSP, EDR, and custom reports.
How it Works
Unlike most environmental reporting systems, PI-DAS doesn’t operate in a silo. Built directly on the PI System, PI-DAS houses all environmental compliance data in the same ecosystem as your operational data.
- Raw data from analyzers and instrumentation is stored in PI
- Real-time validation and averaging are applied using rules-based logic
- Final and intermediate results are written back into PI
- Data is viewable in dashboards and ready for export in reports.
- Full calculation traceability and transparency make audits simple
Key Capabilities
Acquisition: Real-time acquisition of raw data into the historian
- Raw data, analyzer status from PLC’s, DCS’s, CEMS
- Calibration gas values, maintenance status, fault signals
- Heating values, F factor, moisture, etc.
Validation: Raw data validation, range, in-control & roll-up to averages
- Real-time block and rolling averages
- Automatic exclusion from averages of invalid data due to fault or maintenance
- Out of control determination and drift correction
- Timely notification of invalid data, analyzer faults, out-of-control (OOC)
Roll-up: Hourly and block average
- Timely notification of exceedances – emission, concentration, opacity
- Prompting for R&A inputs for monitoring equipment malfunctions and exceedances
- Missing data procedures, if required
Aggregation: Aggregation of hourly and block data to daily, monthly, and quarterly values by emission source and/or facility
Reporting: Automatic data transmission and reporting to regulatory agencies; production of operational and compliance reports (EDRs)
Advanced automation: Compliance averaging using quality-assured, validated data; automated preparation of calibration, EEMSP, EDR, and custom reports.
