How it works

How it works?

  • UniSim Design accurately calculates physical, transport, separation, and reaction kinetic properties. Market-leading, it is field-proven to give realistic results in both steady-state and dynamic environments
  • Users can quickly create robust, realistic process simulation models to use for offline and online (Digital Twin) applications
  • Reduce downtime by quickly identifying process constraints
  • Fast Solving of large, complex problems: EO modeling improves robustness, speed and power (optimization cases run up to 10x faster)

The Technology Platform Delivery At UOP

Due to its modeling versatility and flexibility, UniSim Design is utilized across much of the UOP organization, including groups such as Process Modeling, New Process Development, Engineering, and Connected Performance Services, which are described further in this paper.

Practical Applications of a Dynamic Digital Twin

Comprehensive Digital Twin process models provide engineers with a complete view of heat and material balances for evaluating limiting design cases and other operating conditions. Engineers leverage this information to ensure designs are safe, meet environmental regulations and maximize the operational and business performance of the asset.

Faster Decision Making on Crude Blend Compatibility

While the decision to blend cheaper crudes might seem an obvious choice, incorrectly blended crude oils can precipitate asphaltenes, which are difficult to re-dissolve and can impact the pre-heat train performance. Learn how UniSim Design can support faster decision making by supporting refineries to estimate crude blend compatibility, utilizing the Crude Assay data.

UniSim Design Tips and Tricks

For LNG production optimization, it is essential to have a model with access to many parameters and operating conditions which impact the performance of the unit. The UniSim Design EO platform is unique in providing extensive optimization capabilities, including lifecycle modeling and online optimization utilizing real-time data.
