Aspen HYSYS is a workflow-oriented process simulation software specifically designed for optimizing both conceptual design and daily plant operations. Its broad feature set addresses engineering challenges across multiphase flow modeling, gas processing, refining, and LNG—making it the most versatile solution in the energy sector. What truly sets HYSYS apart is its workflow-oriented design. Every functionality, from economics to energy analysis, is engineered to save time and integrate seamlessly into an engineer's daily work.
Natural gas must be treated to remove impurities like carbon dioxide and hydrogen sulfide. HYSYS is highly effective at simulating amine sweetening units, glycol dehydration, and cryogenic Natural Gas Liquefaction (LNG) processes where precise heat integration is vital.

When an operating plant suffers from reduced throughput or off-specification products, engineers replicate the issue inside HYSYS. By matching the simulation to real-world plant data, they can isolate bottlenecks—such as an undersized control valve or a fouled heat exchanger—and test solutions virtually.

At its core, Aspen HYSYS is a powerful process modeling tool that allows engineers to create rigorous steady-state and dynamic models of chemical and physical processes . It performs the critical calculations of chemical engineering: mass and energy balances, vapor-liquid equilibrium, heat and mass transfer, chemical kinetics, and pressure drop across a process .
