Crude Approval Grids

The results for each possible blend can be compared to existing CAGs. See Crude Approval Grids. Select Crude Approval Grid from the Display dropdown menu in the Graph page, then select the name of the required CAG from the dropdown menu below it. When you generate the BlendGraph, the colour of each cell indicates whether the corresponding blend meets the requirements of the CAG. To review the results of the CAG for a particular blend, right-click the required blend on the graph and select Go To Blend Page to open the Blend Page for that blend.

Property

The results for a particular cut property of each possible blend can be displayed on the BlendGraph. Shading is used to indicate the variation in property with the changing blend ratios.

To edit the property and cut displayed on the graph:

• Select Property from the Display list.

• Select the required property using the Property menu.

• Select the required unit from the Unit menu.

• Using the Cut Type menu, select either a Standard cut and select the required cut, or select Custom and enter the required cut points and temperature unit.

• Click the generate () icon to create the graph.

Nearness

The Nearness option only appears if you have at least one nearness crude configured. See Compare Assays using Nearness.

• Select two or three crudes.

• Select Nearness from the Display list.

• Select one of the nearness crudes from the drop down.

• Click the generate () icon to create the graph.
