System Requirements — Aspen Hysys
AspenTech has announced incremental changes for upcoming versions (V15, expected 2025):
Always refer to the (Article ID: 123456 – “System Requirements Matrix”) for version-specific updates before procurement.
While the requirements are consistent across recent versions, the official AspenTech documentation for and V9.1 provides a solid baseline. These specifications are the most reliable source for system requirements, as later versions typically maintain similar or slightly higher demands.

Engineers frequently link HYSYS data to Excel for reporting, equipment sizing, and economic analysis.
Intel Core i7 (13th/14th Gen) or AMD Ryzen 7 (7000/8000 series) Memory: 32 GB DDR5 RAM Storage: 1 TB NVMe SSD
Hardware requirements vary based on the scale of your process models. Simulating a single distillation column requires far less power than running a plant-wide dynamic simulation with complex oil characterizations.
