Property Manager

The Property Manager is a specialist tool to enable you to add and configure new properties, representing possible measurements which can be made on a crude or crude products.

You can launch the Property Manager by:

• Choosing Property Manager from the View menu, or

• Pressing the button on the toolbar.

Process Model Manager Reference Manual is distributed with a set of industry standard properties. The complete set of these properties can be found in Properties.

New properties can be defined, and configured in considerable detail. The available configuration allows you to specify:

• Names, including abbreviated names, for the property

• The unit category, and default units for the property

• Boiling point ranges for valid cuts

• Valid ranges for property values

• Display formats, including standard display units and precisions

• Blending behaviour including blend basis (weight or volume) and formulaic blending indices (including non-linear indices)

• Blending behaviour on crude

• Correlations which can be used if property measurements are absent

• Graphability of the property as a profile

• Measurements tolerances (as formulae) used to control fitting of profiles

• Multiple constraints on fitting profiles, including value constraints and monotonicity

• Control of tension, and extrapolation behaviour for fitting profiles

The following guide to the Property Manager makes use of a simple example, of adding Basic Nitrogen as a property, and configuring its behaviour.
