Lummus Digital

Petrochemicals

Peak Performance. Product Consistency. Enhanced Profitability. 

Lummus Digital enables intelligent plant operations by combining deep process expertise with AI and advanced data analytics. With Hybrid Process Modelling at the core, we drive performance, reliability, and efficiency across the petrochemical industry.

Leveraging autonomous intelligence built into the AI/ML-powered platform mcube™, operations are enhanced by continuously interpreting real-time data, learning from process behavior, and adapting without manual intervention. This delivers context-aware insights tailored to evolving plant conditions—enabling timely actions that improve asset availability, ensure product quality, and maintain operational stability.

The Look, Listen, and Feel (LLF) automation is particularly valuable for petrochemical operations. It captures operator observations—visual cues, auditory signals, and tactile feedback—and converts them into structured, real-time intelligence that, once integrated into our reliability framework, enhances situational awareness and enables earlier, more accurate detection of potential issues.

Lummus continues to build it capability and expertise in petrochemicals and has a wide-range of solutions that address unique challenges in this industry.

Pain Point

Benefit

Get accurate Heater COT set points tailored to your feed using optimizer insights and PYPS+ analysis

Pain Point

Benefit

Unlock insights with the Scenario Analysis feature, which provides the potential yield based on Naphtha feed composition

Performance Metrics

Performance Deviation Prediction

The PYPS+ Model takes the Plant Feed Composition, Feed rate, and the current DCS operating data as input

The operator selects the mode of optimization:
1.Margin Optimization (Profit maximization)
2.Yield Optimization (Increase in Propylene + Ethylene Yield)

Based on the optimizer mode selection and the Scenario Analysis run (PYPS+), the RTO provides setpoints for the operator to achieve the desired results.

The model re-runs a scenario analysis after the optimizer run is complete to analyze actual results in PYPS+ once the changes are implemented.

Margins are calculated for before RTO, with RTO, and after RTO to assess profit impact, and the results are published in a report.

Takes the DCS and LIMS data with respect to the Ethylene Fractionator for further analysis and processing.

Checks the Ethylene Product Quality against the Design Specifications. Checks for the Ethylene concentration on the Control Tray and publishes an Alert Run
 

The alert indicates if the unit is operating normally (displays “Ethylene Product is on-spec”) or not, and provides recommended operator actions and upcoming event forecasts.

The model runs and publishes recommended values for operator-controlled setpoints to achieve lower vent rates, minimize ethylene slip, and maximize on-spec ethylene product rates.
