Overrides for component property data

When you change the pure component data that you use in a Fluid Type, you typically make changes to a custom data bank in AVEVA Thermodynamic Data Manager and then add that custom data bank to the Fluid Type. If you want to make small changes, this can be cumbersome and time consuming.

Instead, you can use the Component Data section in the Fluid Editor to locally override the pure component thermodynamic data from the default and custom data banks. These changes apply only to the Fluid Type and do not propagate back to any of the data banks stored in AVEVA Thermodynamic Data Manager. If you want to apply these changes to multiple Fluid Types, we recommend that you update your custom data banks instead of locally overriding the pure component thermodynamic data.

Tabs in the Component Data section are available only after you add components to your Fluid Type. Use the Constants tab and the Temperature Dependent tab to change the data for constant properties and temperature-dependent properties, respectively.

You can override the constant property data for both pure components and petro components. You can also override the temperature-dependent property data for both pure components and petro components. However, for petro components, certain temperature-dependent properties are calculated by using the petro components parameters, such as critical temperature (Tc), critical pressure (Pc), and specific gravity (SG). You cannot override the data for the calculated temperature-dependent properties.
