Process Modeling (HYSYS) by AspenTech is a leading process simulation platform used to design, optimize, and troubleshoot oil and gas, refining, and petrochemical operations. It unifies steady-state and dynamic simulation in one environment, enabling engineers to evaluate plant performance across design, startup, shutdown, and upset conditions. Aspen HYSYS offers robust thermodynamic property methods and a comprehensive library of unit operations, including rigorous distillation columns, reactors, compressors, heat exchangers, pipelines, and separation equipment. Specialized capabilities support gas processing (such as amine sweetening, dehydration, and cryogenic/NGL recovery), LNG, and refining workflows.
The software integrates with AspenTech’s broader toolset for exchanger sizing and rating, flare and relief analysis, energy and sustainability assessments, and economic evaluation, helping teams move efficiently from concept to detailed design and decision-making. Built-in case studies, sensitivity analysis, and optimization tools streamline scenario evaluation and debottlenecking. Dynamic modeling supports controller design and tuning, operability studies, surge and depressurization analysis, and operator training.
With accurate material and energy balances, equipment performance insights, and clear reporting, Aspen HYSYS helps improve process safety, increase throughput, reduce energy use, and shorten project cycles—from greenfield designs to brownfield revamps and day-to-day troubleshooting. more
