At VL Energy, we understand the complexities and importance of accurate emissions monitoring. Our process for building a Predictive Emissions Monitoring System (PEMS) is thorough and tailored to meet the unique needs of both regulated and non-regulated entities. Here’s a detailed look at each step in our process:
1. Data Collection
- Regulated Entities: For facilities regulated with existing Continuous Emissions Monitoring Systems (CEMS), we directly request historical emissions data. A two-week dataset typically provides a sufficient baseline to understand the emissions profile.
- Non-Regulated Entities: In cases where no CEMS is present, we deploy a portable gas analyzer to gather necessary emissions data over a similar two-week period. This data helps us tailor our approach to the specific characteristics of the site.
- Lacking Data: If a facility lacks accessible emissions data, we communicate with third-party controllers to obtain data from any centralized control systems in place, ensuring we have the comprehensive insights needed to proceed.
2. Data Preparation
Data integrity is crucial for the next steps. We meticulously clean the data by smoothing out irregularities and removing outliers that could skew our model’s accuracy. This stage is vital as the quality of data significantly influences the machine learning aspect of our PEMS, ensuring the predictions are reliable and precise.
3. Development Process
- Feature Selection: We select key parameters and features that most influence the emissions data. These parameters typically include operational settings that vary across different types of equipment and target gases identified in the emissions data.
- Machine Learning Model: We develop a machine learning model that discovers and learns the relationships between the sensor data and the emissions outputs. This model is crucial for enabling ongoing monitoring and predictive capabilities.
4. System Integration
- Backend Development: After model training, we integrate the model into our backend cloud infrastructure. This integration allows for the continuous real-time monitoring of emissions, which is essential for timely compliance and operational adjustments.
- Frontend Development: We design and deploy a user-friendly dashboard that visualizes the data, allowing clients to easily monitor their emissions and understand their impact. This interface is critical for client engagement and usability.
5. Testing and Validation
RATA Testing: To validate our PEMS, we conduct Relative Accuracy Test Audits (RATA) to compare the data output from our PEMS with that from established CEMS units. This testing is crucial to ensure the alignment and accuracy of our PEMS model.
6. Monitoring, Predicting & Reporting
Our system offers continuous monitoring in real-time, with an impressive 99.5% data availability, ensuring you have a complete picture of your emissions at all times. The intuitive dashboard is accessible on all devices, providing instant insights and seamless access to your data from anywhere.
With built-in auto-reporting features, compliance and regulatory reporting become streamlined and hassle-free. By leveraging real-time data and predictive capabilities, our solution goes beyond traditional monitoring, empowering you to proactively manage emissions and optimize operations.
