Data banks for a Fluid Type

In many places throughout the Fluid Editor for compositional Fluid Types, you can specify custom thermodynamic data that you want to use to supplement the AVEVA Process Simulation data banks for the thermodynamic calculations. This custom thermodynamic data exists in data banks in custom thermodynamic libraries that you have created in AVEVA Thermodynamic Data Manager.

Except for the pure component data bank selection, you will see an Expand button to the right of a list of the data banks that the Fluid Type currently uses for the related thermodynamic data. The order of the data banks in this list is also the order in which AVEVA Process Simulation searches the data banks for data. When AVEVA Process Simulation finds the requested data in a data bank, it stops searching and does not consider any data in subsequent data banks. We recommend that you add data banks with the latest or most relevant data to the top of the list.

When you select Expand, it is replaced with Collapse, and a set of commands and a list of available data banks appears. You can use the two lists and commands to add data banks to the Fluid Type, remove data banks from the Fluid Type, and change the search order of the data banks.

For the pure component data banks, AVEVA Process Simulation loads data for each pure component from the data bank that you specified when you added the component to the Fluid Type. The Bank column in the Component List section of the Fluid Editor shows the data bank that AVEVA Process Simulation uses for each component. You can also supply a custom data bank that contains data that will override those values. To do this, first create a custom data bank that contains the components of interest and enter data for only the property values that you want to override for these components. Then, in the Methods area, in the Pure Component Property Override Data Bank box, enter the name of that data bank in a <library>:<bank> format, where <library> is the name of the library file and <bank> is the name of the data bank within that library file. The library file must be located in the %userprofile%\My Thermo Data folder or in a sub-folder within My Thermo Data.

See the AVEVA Process Simulation Thermodynamics Reference Guide for more information regarding the creation and management of these custom libraries and data banks.
