Aspen Polymers. Polymer Characterization and Physical Properties

Aspen Technology, Inc. Version Number: V8.0. December 2012. - pp. 253. Aspen Polymers (formerly known as Aspen Polymers Plus) is a general-purpose process modeling system for the simulation of polymer manufacturing processes. The modeling system includes modules for the estimation of thermophysical properties, and for performing polymerization kinetic calculations and associated mass and energy balances.The Aspen Polymers User Guide is divided into two volumes. Each volume documents features unique to Aspen Polymers. This User Guide assumes prior knowledge of basic Aspen Plus capabilities or user access to the Aspen Plus documentation set. If you are using Aspen Polymers with Aspen Dynamics, please refer to the Aspen Dynamics documentation set.Volume 1 provides an introduction to the use of modeling for polymer processes and discusses specific Aspen Polymers capabilities. Topics include:
Polymer manufacturing process overview - describes the basics of polymer process modeling and the steps involved in defining a model in Aspen Polymers.
Polymer structural characterization - describes the methods used for characterizing components. Included are the methodologies for calculating distributions and features for tracking end-use properties.
Polymerization reactions - describes the polymerization kinetic models, including: step-growth, free-radical, emulsion, Ziegler-Natta, ionic, and segment based. An overview of the various categories of polymerization kinetic schemes is given.
Steady-state flowsheeting - provides an overview of capabilities used in constructing a polymer process flowsheet model. For example, the unit operation models, data fitting tools, and analysis tools, such as sensitivity studies.
Run-time environment - covers issues concerning the run-time environment including configuration and troubleshooting tips.
Volume 2 describes methodologies for tracking chemical component properties, physical properties, and phase equilibria. It covers the physical property methods and models available in Aspen Polymers. Topics include:
