Physics Meets AI: Hybrid Models for Optimization.

CDU/VDU Optimization ensures your unit runs at peak efficiency—boosting side-stream yields, reducing losses, and unlocking significant cost savings across your operations.
 
At the core of this optimizer is a hybrid AI model designed to maximize the flow rates of Side Stream 1, Side Stream 2, and SPVGO by optimizing the movement of the Vacuum Tower Bottom (VTB) product into the column’s middle section.
 
By leveraging real-time DCS data, it ensures that viscosity, flash point, and VTB penetration number remain within specification limits.

CDU & VDU Predictor and Optimizer

Hybrid Model

Our model leverages real-time, high-frequency predictions of viscosity, flash point, and VTB pen test values to deliver precise operator setpoints for optimizing key variables. These include:
 
  • Stripping steam flow rate
  • Pump around flow rates and temperatures
  • Reflux flows
  • Draw rates with information on draw temperatures

Additionally, it provides optimized values for viscosity, flash point, and VTB pen test, ensuring consistent on-specification product quality while improving overall column efficiency and performance.

Transform your Challenges into Opportunities

The CDU/VDU Optimization Model aims to achieve maximum conversion by utilizing DCS and Feed Quality data in real-time. The AI/ML platform delivers essential DCS set points and recommendations for plant operators and process engineers, facilitating the achievement of desired product rates.
 
Experience increased recovery, real-time predictions of downstream product quality parameter values, and transform your operations for enhanced efficiency and profitability!

Performance Metrics

Performance Deviation Prediction

Operator enters the estimated crude mix on the dashboard and initiates the run.

The Crude Mix Model calculates the accurate crude mix and displays the results on the dashboard.

Every two hours, the prediction model runs to predict the Viscosity, Flash Point, and VTB Penetration Test values at operating conditions.

Using the corrected crude mix and predicted product quality parameters, the Optimizer Model runs and populates a table of actual and optimized/recommended values.

A comparison plot between “Current Operation” and “Optimized Operation” is displayed on the dashboard for operator action.
