Aspen Hysys System Requirements [2021] Jun 2026

A single large-scale refinery simulation with a thermo package like Peng-Robinson can easily consume 18-22GB of RAM. Adding a dynamic pressure relief scenario pushes that to 30GB+.

64 GB is advised if you are running HYSYS alongside other heavy hitters like Aspen Plus, AVEVA, or large Excel-based automation tools. 3. Graphics Card (GPU) Aspen Hysys System Requirements

Intel Core i5 or i7 (2.8 GHz or faster) is the baseline. For V14, newer Intel Core Ultra or Xeon Gold series are recommended for heavy lifting. A single large-scale refinery simulation with a thermo

are recommended to fully utilize available RAM for large-scale process modeling. 3. Deployment Variations Depending on your use case, requirements may change: Standalone vs. Server: are recommended to fully utilize available RAM for

On an i7-12700K / 32GB DDR4, the “Crude_Distillation.hsc” sample should solve in under 3 seconds fully converged.
