Aspen Hysys System Requirements Guide
Will you be running simulations or heavy dynamic simulations?
For steady-state simulations, single-core performance (high GHz) is more critical than having dozens of cores. Look for a base clock speed of 3.0 GHz or higher , with turbo boost reaching 4.5 GHz+.
| Task | Recommended CPU | Recommended RAM | Notes | | :--- | :--- | :--- | :--- | | (simple 2-unit ops) | Any i5, 2.0 GHz | 8 GB | Use Aspen HYSYS Educational (lighter logging) | | Crude Distillation Unit (CDU) | i7, 4.0 GHz+ | 32 GB | Atmospheric + Vacuum + side strippers | | Gas Processing (Amine + TEG) | i7, 4.2 GHz+ | 32 GB | Property package: Acid Gas – high memory | | Dynamic Simulation (10 min real-time) | i9 / Ryzen 9, 5.0 GHz+ | 64 GB | Needs smaller time steps; more variables in memory | | Optimization (100+ case studies) | 12+ cores (parallel) | 64 GB | Can run overnight – ECC RAM recommended | | Flare System ( linked to HYSYS) | i9, 5.0 GHz+ | 64 GB | Each relief scenario spawns a new solver instance | | Liquefied Natural Gas (LNG) | Dual Xeon / Threadripper | 128 GB | Multi-train, multi-pass plate fin heat exchangers | Aspen Hysys System Requirements
If you are using a Mac (M1, M2, M3, or Intel chips), you cannot install Aspen Hysys directly. You must use one of the following workarounds:
: Windows Server 2012 R2 or later (for server-based deployments). Network Will you be running simulations or heavy dynamic simulations
Graphics card and monitor supporting a minimum resolution of 1280 x 1024
If your organization uses a concurrent network license, a stable Local Area Network (LAN) or Virtual Private Network (VPN) connection to the AspenTech License Server is required. | Task | Recommended CPU | Recommended RAM
Pro, Enterprise, and Education editions (Highly recommended for V14).
On an i7-12700K / 32GB DDR4, the “Crude_Distillation.hsc” sample should solve in under 3 seconds fully converged.
NVIDIA Quadro or AMD Radeon Pro drivers offer verified stability for engineering applications. 6. Display and Resolution
If you are a student or a casual user, a modern with 16GB of RAM will get the job done. However, if you are a professional working on dynamic simulations or massive integrated gas plant models , investing in a workstation with 32GB of RAM and an i9 processor will save you hours of processing time every week.
