Aspen Plus®

Conceptual design of chemical processes


Aspen Plus is a market-leading process modeling tool for conceptual design, optimization, and performance monitoring for the chemical, polymer, specialty chemical, metals and minerals, and coal power industries. Aspen Plus is a core element of AspenTech’s aspenONE® Process Engineering applications.

Features

  • Best-in-class physical properties methods and data. Aspen Plus includes the world’s largest database of pure component and phase equilibrium data for conventional chemicals, electrolytes, solids, and polymers. Regularly updated data from the U.S. National Institute of Standards and Technology (NIST) ensures easy access to the best available experimental property data, enabling process engineers to save months of effort when developing chemical process models. AspenTech and NIST were recently awarded a prestigious R&D 100 Award Award for software innovation in recognition of the importance and impact of our collaboration for the Chemical Processing Industries.
  • Improved conceptual design workflow. Aspen Plus has been tightly integrated with AspenTech’s industry-leading cost analysis software and heat exchanger design software. Process engineers can rapidly estimate the relative costs of proposed designs and make decisions based on capital and operating cost estimates using proven cost modeling technology. Key equipment such as heat exchangers and distillation columns can be rigorously sized or rated from within the simulation environment. The tight integration of design and costing software with process simulation eliminates costly manual iterations and promotes more optimal designs based on rigorous cost estimates.
  • Scalability for large and complex processes. Aspen Plus’s unique Equation Oriented (EO) modeling capability and hierarchical flow sheeting lets you simulate even the most large scale and complex processes; even highly integrated processes with multiple recycles. Customers can build models spanning entire sites to find the globally optimal operating conditions.
  • State of the art column internals calculations for flooding and pressure drop. Aspen Plus includes a library of more than 300 packings and 5 different tray types with parameters fitted for calculation of tray internals.
  • Aspen Plus provides users with rate-based distillation technology which enables distillation calculations while accounting for rigorous mass transfer on trays or on packings. This technology has been used to model amines-based carbon capture and other separations.
  • Aspen Plus also enables users to model batch distillation in a rigorous manner.
  • Additionally, Aspen Plus also enables users to identify azeotropes and residue curves which can help users to design and synthesize non-ideal distillation columns.
  • Aspen Plus also provides users with a complete set of polymer thermodynamics methods and data, rate-based polymerization reaction models, and a library of industrial process models.
  • Online deployment of models as part of an open-loop operator advisory system or in closed-loop, real-time optimization/advanced process control applications when used with Aspen Online Deployment™ and Aspen Simulation Workbook™.
  • Workflow automation. Aspen Plus 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.
  • Aspen Plus Dynamics® is used for safety and controllability studies, sizing relief valves, optimizing transition, startup, and shutdown policies.
  • Links to third-party tools. Aspen Plus includes links to several well-known tools including the OLI’s electrolyte package and Technip’s SPYRO ethylene cracker models.
