Locate the Thermodynamics node and right-click to add an
External Thermodynamic System (
Figure 6-2). Using a
Reaction Engineering interface, you can also add an external package by choosing
External Thermodynamic System from the
Thermodynamics section of the
Reaction Engineering toolbar.
All installed packages, from providers such as COCO/TEA, Aspen Properties, etc, are available in the Thermodynamic System Wizard (
Figure 6-9). Select one of the packages and click the
Finish button (
) in the upper right corner of the wizard in order to add the package to the
Thermodynamics node.
When adding the package its default label reflects the included phases. For example, a node labeled Vapor-Liquid System (External) is created when adding an external package containing a vapor and a liquid phase.
Selecting the External Thermodynamic System node shows the thermodynamic system settings with sections for available species, phases, species properties, and mixture properties.
