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

* Efficient workflow for process design, equipment sizing, and preliminary cost estimation within one environment through integration with other aspenONE Process Engineering tools including Aspen Icarus Process Evaluator™ cost modeling software and Aspen HTFS+® heat exchanger design tools.
* 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™.
* Unique equation-oriented architecture. Aspen Plus’s unique combination of sequential-modular and equation-oriented solution technologies facilitates the simulation of wide-scale, integrated chemical processes.
* Best-in-class physical properties methods and data. Aspen Plus includes extensive databases of pure component and phase equilibrium data for conventional chemicals, electrolytes, solids, and polymers. Ongoing collaboration with the U.S. National Institute of Standards and Technology ensures easy access to the best available experimental data and methods.
* Comprehensive library of unit operation models to address a wide range of solid, liquid, and gas processing equipment. The open architecture lets you build your own libraries of unit operation models with Aspen Custom Modeler® or programming languages. CAPE-OPEN compliant models can be also be used with Aspen Plus.
* 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.
* 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.

Options

A number of optional extensions are available to enhance the value of Aspen Plus:

* Aspen Dynamics® is used for safety and controllability studies, sizing relief valves, optimizing transition, startup, and shutdown policies.
* Aspen RateSep™ improves the rigor and accuracy of the distillation models using proven rate-based technology.
* Aspen BatchSep™ is a dynamic batch distillation modeling tool that can be run stand-alone or inside an Aspen Plus flowsheet.
* Aspen Polymers Plus® extends Aspen Plus with a complete set of polymer thermodynamics methods and data, rate-based polymerization reaction models, and a library of industrial process models.
* Aspen Split™ is used for the conceptual design of distillation schemes for separation of mixtures with non-ideal vapor liquid equilibrium behavior.
* Aspen Plus Optimizer™ enables equation-oriented optimization and data reconciliation.
