Aspen Hysys |best| Jun 2026

In the world of chemical engineering and process design, few software packages command the respect and widespread utility of (formerly known simply as HYSYS). Originally developed by Hyprotech in the late 1970s and now a flagship product of AspenTech, Aspen HYSYS is an industry-leading process simulation tool used extensively for steady-state and dynamic process modeling.

While less common than Aspen Plus, HYSYS is used for olefins, polymers, and any process involving complex hydrocarbon loops. aspen hysys

Aspen HYSYS is the industry-standard simulation software used by chemical engineers for steady-state and dynamic process simulation, primarily in the oil & gas, refining, and gas processing industries. It is known for its robust thermodynamic packages, particularly for hydrocarbon processing, allowing for accurate modeling, optimization, and troubleshooting of industrial plants.
