Aspen HYSYS®

Process modeling tool for conceptual design and performance improvementof petroleum and oil & gas processes

Aspen HYSYS is the market-leading process modeling tool with a proven track record of providingsubstantial economic benefits throughout the process engineering lifecycle. It brings the power ofprocess simulation to the engineering desktop, enabling companies to bring new plants and designsto market faster and more efficiently at a higher return on investment.

The Challenge: Adapting to Change,Optimizing Plant Performance

Across the process industries, companies are challenged with global

economic growth, constantly changingmarket conditions, and pressure

to reduce time-to-market. As the cost of crude oil and energy

continues to escalate, oil & gas producers, refiners, and E&C firmsmust

creatively reduce capital and operating costs and increase engineering

efficiency—all in an effort to maximize plant performance

and profitability.

The AspenTech Solution: Better SimulationStreamlines Engineering

Fundamental to improving performance of the plant or enterprise, or

even the extended supply chain, is an accurate representation of the

basic processes. Companies need a solution that enables them to gather that information and build the models required to optimize

enterprise performance. Aspen HYSYS provides the solution to meet this need, solving the critical engineering and operating

problems that arise throughout the plant lifecycle.

The process simulation capabilities of Aspen HYSYS enable engineers to rapidly evaluate the safest and most profitable designs

through quick creation of interactive models for “what-if” studies and sensitivity analysis.These models can be leveraged throughout

the plant lifecycle—from conceptual to detailed designs, rating, and optimization—significantly reducing engineering costs and

enabling better operating decisions. Other benefits include:

• Improve engineering productivity

• Ensure accuracy and timeliness of engineering designs

• Provide engineering support to plant operations

• Support EHS policies and regulatory compliance

• Integrate with other aspenONE® Engineering solutions to provide a common engineeringworkflow for the refining, E&P, and E&C industries
