Figure 1: Predictive Maintenance Data Stream for Heat Exchangers in Polyethylene Process Manufacturing
This data stream monitors and predicts maintenance needs for heat exchangers in polyethylene manufacturing by integrating telemetry, operational, and environmental data with a digital twin model. The combined data is broadcast to predictive models and anomaly detection systems, which forecast fouling and equipment failures while identifying critical conditions. Actionable maintenance recommendations are generated, ensuring proactive maintenance and optimal performance. The results are delivered through the XMPro App, reducing downtime and maintaining efficient production cycles.

Figure 1. High Temperature on Base Bearing Recommendation
This recommendation identifies a high temperature condition on the robotic arm’s base gearbox bearing, triggered by AI model logic. It enables early detection of potential issues, minimizing downtime and extending equipment lifespan. Users can add notes, assign, share, and create work requests with special instructions. The system tracks whether the recommendation solved the problem or was a false positive, ensuring timely responses and continuous improvement in predictive maintenance.

Figure 2. Configure With Granular Rule Logic
This example demonstrates how XMPro’s recommendation system can be configured using granular rule logic, AI model logic, or a combination of both. The rule triggers when temperature data from the data stream exceeds a specified threshold. The embedded AI model continuously analyzes sensor data to detect anomalies and predict potential issues. When triggered, the system can take actions such as sending notifications, creating work requests, and executing other predefined actions.

Figure 3. Close The Loop On Event Response
Closing the loop on event response, the system can take various actions, including sending email and SMS notifications for new recommendations, status changes, note updates, and pending times. Additionally, it can automatically create work orders, send information to ERPs, and execute other predefined actions, ensuring comprehensive monitoring and immediate response to turbine issues with detailed guidance and timely alerts.

This advanced dashboard provides operators of polyethylene manufacturing plants with a comprehensive view of their heat exchanger infrastructure. It features an interactive layout that dynamically updates with the condition of various heat exchangers, offering a clear visual representation of their operational health.

KEY FEATURES:

  • Live Telemetry: Displays real-time data on key parameters such as temperatures at different points (inlet and outlet for both shell and tube sides), overall duty, and general area specifics.
  • Asset Metrics: Shows a gauge indicating the effective utilization percentage of the heat exchanger.
  • Time Profile (24 Hours): Provides a visual graph of the heat exchanger’s running time over the past 24 hours.
  • U Coefficient View: A historical trend graph showing the U coefficient over time, highlighting any significant changes or trends that may indicate fouling or performance issues.
  • Operational Safety Intelligence: Displays hazard descriptions, control measures, and probability assessments for potential safety risks, such as high temperatures.
  • Recommendations: Lists actionable maintenance recommendations, with alerts for issues such as the start of fouling, including specific details like the coefficient value and the time of detection.

Each element on the dashboard is designed to give operators immediate, actionable insights, ensuring proactive maintenance and optimal performance of the heat exchangers, ultimately reducing downtime and maintaining efficient production cycles.

Figure 1: Heat Exchanger Predictive Maintenance – Heat Exchanger Health Data Stream
Embedding XMPro AI Agents in XMPro Data Streams enables executable AI and machine learning for algorithmic business processes, significantly enhancing the capabilities of operational digital twins. This integration allows for advanced features such as real-time analytics, MLOps, and seamless embedding of AI into core business processes. In this example of heat exchanger predictive maintenance, XMPro’s AI Agents empower the data stream to accurately identify and predict potential heat exchanger fouling issues.

The process begins with the ingestion of critical sensor data including temperature, flow rate, and pressure. This real-time data is enriched with contextual information from maintenance logs and a digital twin of the heat exchanger, providing a comprehensive view of the operational state.

Machine learning models, including fouling prediction and predictive failure models, are applied to the enriched data to forecast performance declines and potential failures. Anomaly detection models further enhance predictive capabilities by identifying deviations in heat exchanger performance. The results are then broadcasted to different predictive models and continuously updated in the XMPro iBOS platform for comprehensive analysis and actionable insights.

By combining real-time data integration, predictive analytics, and automated maintenance recommendations, this data stream ensures efficient and reliable polyethylene production by proactively managing heat exchanger fouling.
