shown here changes as you configure the model.
7.2.8 Worksheet Tab
The Worksheet tab consists of four pages:
• Conditions
• Properties
• Composition
•PF Specs
Conditions Page
The Conditions page displays the default stream information as
it is shown on the Material Streams tab of the Workbook
property view. You can also view the conditions for the ACM
streams by double-clicking on the Name field of the stream to
open the Conditions page in the Material Stream property view.
Properties Page
The Properties page displays the properties for each ACM stream
phase. You can also double-click on the Name of the stream to
access the Properties page in the Material Stream property view.
From there you can add or remove properties for an ACM Op
stream. The properties from the Conditions page are not
available on the Properties page.
The enthalpy values for the inlet ports are calculated by
HYSYS. These values should be used with caution by the ACM
model as they might not be consistent with those in the
Aspen Property file. In your ACM model, you can use a
properties call to calculate a valid enthalpy based on the
inlet temperature, pressure, and composition.
In steady state, the ACM Op usually requires its inlet streams
to be fully specified (solved) before the operation can solve
the outlet streams.
