Aspen HYSYS is a market-leading process modeling tool for conceptual design, optimization, business planning, asset management, and performance monitoring for oil & gas production, gas processing, petroleum refining, and air separation industries. Aspen HYSYS is a core element of AspenTech's aspenONE® Engineering applications.

Features

Easy to use and easy to train. Aspen HYSYS has established itself as a very intuitive and easy to use process simulator in the oil & gas and refining industry. Users with little prior knowledge of Aspen HYSYS can pick up and train themselves in its modeling capabilities. Some of the very intuitive capabilities include a highly interactive process flow diagram for building and navigating through large simulations. The program also provides a very flexible and easy to use distillation column modeling environment. Additionally the interactive nature of HYSYS enables users to build and use their models quickly and effectively.
Best-in-class physical properties methods and data: Aspen HYSYS offers a comprehensive thermodynamics foundation for accurate calculation of physical properties, transport properties, and phase behavior for the oil & gas and refining industries. V7 and newer versions of HYSYS have almost doubled in its capabilities on physical properties. These versions can perform very accurate calculations of natural gas, LNG, hydrate, CO2 freeze-out and dehydration calculations. Additionally electrolyte calculations such as sour water stripping and amine systems can be done with ease. The heavy end oil methods in refining are also the state of the art.
Aspen HYSYS features state of the art assay management and propagation of refinery molecules across the flowsheet. It also features integration with 3rd party programs such as SpiralSoft and Haverly systems.
Comprehensive library of unit operation models including distillation, reactors , heat transfer operations, rotating equipment, controllers, and logical operations in both the steady state and dynamic environments. CAPE-OPEN compliant models are also fully supported.
Aspen HYSYS introduced the novel approach of steady state and dynamic simulations in the same platform. By thus bringing steady state and dynamic simulations together in a single user-friendly environment, HYSYS revolutionized simulation. It has became the defacto standard in industry, and today enjoys universal acceptance with small consultants, large E&Cs, and owner/operators in the area of dynamic simulation.
The program provides state of the art pipeline network and pressure drop analysis capabilities in both steady state and transient flow. AspenTech has also integrated 3rd party pipeline network and well models technology (OLGA, PIPESYS, PIPESIM and GAP) from SPT , Neotec, Schlumberger and Petroleum Experts, respectively. Aspen HYSYS Upstream™ provides the E&P industry standard methods and techniques for handling petroleum fluids and brings together the disciplines of petroleum and process engineering.
Aspen HYSYS provides users with refinery reactor technology in simulation and calibration modes in a seamless manner. The refinery reactor technology that is integrated within the HYSYS environment includes Fluidized Catalytic Cracking, hydrocracking and hydrotreating, reforming and isomerization. This enables HYSYS to perform single unit, multi-unit as well as refinery wide simulations. Additionally HYSYS features capabilities which allow users to include simplified reactor models in conjunction with rigorous refinery reactor models in their flowsheets and perform refinery wide mass and utility balances. There are also documented interfaces to integrate to third-party refinery reactor models. Aspen HYSYS Petroleum Refining provides the refining industry with a multi-unit modeling tool with an Aspen HYSYS look and feel. It enables users to integrate crude assay libraries, conversion reactor models, and links to LP planning tools for better crude selection, planning and scheduling of operations.
Aspen HYSYS is integrated with Aspen PIMS and Aspen Refinery Scheduler software which provides time and cost saving workflow for performing refinery planning and scheduling model updates.
Efficient workflow for process design, equipment sizing, and preliminary cost estimation within one environment through integration with other aspenONE Engineering tools including Aspen Process Economic Analyzer cost modeling software, Aspen EDR heat exchanger design tools, and Aspen Basic Engineering.
Online deployment of models as part of an operator advisory system for better model-based decision support. The built-in advanced sequential quadratic program (SQP) algorithm for optimization enables offline and online optimization of designs and operating performance.
Workflow automation: Aspen HYSYS models can be linked to Microsoft Excel® using Aspen Simulation Workbook or Visual Basic® and used to automate the engineering workflow and deploy the model to a wider range of end-users in the field.
Links to third-party tools: : Aspen HYSYS includes links to several well-known tools including OLI’s electrolyte package, amines packages, PVT and Black Oil thermodynamics. Aspen HYSYS Amines™ simulates and optimizes gas and liquid sweetening processes involving single or blended amines. An advanced thermodynamic Li-Mather electrolyte model achieves more reliable results than empirical models, especially for blended amines.
ActiveX (OLE automation) compliance permits the integration of user-created unit operations, proprietary reaction kinetic expressions, and specialized property packages.
