Using Digital Twins to Build More Accurate Inferentials for Improved Process Control
Advanced process control (APC) applications require accurate inputs for stream qualities, including product compositions and distillation curve points. While online analyzers are effective in supporting model predictive controllers, they are expensive and often unavailable for important process streams. There is a more cost-effective approach for building virtual analyzers or inferentials to accurately estimate stream qualities and it starts with digital twins.

On-Demand Data Reconciliation for a Fleet of Hydrogen Production Plant
The growing interest in hydrogen as the fuel of the future requires manufacturing plants to be operating efficiently using data-driven methods. With online data servers, engineers have a seemingly infinite amount of data at their fingertips. Reconciling this data for use in more advanced tools or calculations can be a tedious and labor-intensive process.

Use of Surrogate Models to Enhance Rigorous Simulation Performance
Surrogate models (or Reduced-Order Models) allow simulation users to explore and identify optimal process performance conditions faster than full, rigorous simulations. But there are times when users may find they are extrapolating beyond the data used to develop the surrogate model or when there is a desire to confirm the accuracy of the surrogate model. In these cases, the surrogate model can be used to enhance model performance, from both a robustness and performance perspective.

Rapid and Accurate Steam Reformer Model Development Using First Principles Driven Aspen Hybrid Models™
The steam reforming reaction to generate hydrogen from natural gas takes place at high temperatures. Conventional rigorous reactor modeling requires a temperature profile of the process fluid, which is difficult to estimate or measure. Using the latest First Principles Driven Hybrid Models, it was found that a relatively simple model can accurately represent a wide range of plant data. In this presentation, the methodology of first principles driven Aspen Hybrid Models, the importance of data conditioning, comparison with conventional methods and potential benefits are all discussed.
