Process simulation is a cornerstone of modern chemical‑process engineering, enabling engineers to evaluate design alternatives, conduct safety analyses, and predict plant performance before capital investment. Aspen HYSYS, originally released in the early 1990s by Aspen Technology, has evolved into a comprehensive, user‑friendly environment that couples robust thermodynamic models with an intuitive graphical interface. Its popularity stems from:
