The user specifies the incoming flow rates, the extent of con... |
Problem Statement: Do we have an example of a CAPE OPEN standalone property package? | Solution: The implementation of the code inside the CAPE OPEN components, such as how to develop a thermodynamic package, is not the responsibility of AspenTech. What we support is the usage (i.e. calling) the CAPE OPEN components of Aspen Plus.
Attached to this Solution is material developed to illustrate the system u... |
Problem Statement: How can we compute the actual critical point of a mixture? | Solution: This sort of calculation only makes sense with a property method based on an equation of state (EOS). It has to be said that ordinary cubic equations of state such as the popular RK-SOAVE and PENG-ROB are not particularly accurate near critical, besides being limited to hydrocarbons and light gases only.

Problem Statement: Is there a way I can model a single stage batch separation (flash) in Aspen Plus? | Solution: The way model a batch flash, without the use of Aspen Dynamics, is to employ the batch reactor model in Aspen Plus, RBatch. RBatch can be used in Aspen Plus without a reaction set by unchecking the Reactive system box on the Setup\Reactions sheet. In such a case it becomes simply a batch flash block.
