View your blend results

The Blend Detail tab of the Blending page shows the results of blending. The Blend Detail tab breaks down any limits on the blend amounts, which intermediate streams are included in which final product and the qualities of final blended products and their component streams.

Select the Blender and the Product you want to examine from the lists at the top of the tab, and choose a unit of measure for the results from the Solution UoM list.

Clear a check box in the Allowed? column to disallow the corresponding stream in the blend.

The Solution column displays the amount of each component in the blend.

The Blend Detail grid has three options in the Blend Detail group of the Home ribbon tab:

• Show Properties

• Highlight Off-spec

• Show Zero Flow

These are described in the sections below.

Show properties

To see the properties of each final blended product, as well as the component streams of the product, navigate to the Blending > Blend Detail grid, then click on the Show Properties button in the Blend Details group of the Home ribbon tab. Where a particular property has a limit, the limit value is also shown, as well as the final blended value.

Highlight off-spec

To view the property specifications that violate the finished product specification (for each possible component stream), click on the Highlight Off-spec button in the Blend Details group of the Home ribbon tab.

Example: Low sulfur fuel oil could be composed of LVGO, HVGO and vacuum residue, and have a sulfur maximum of 1.5% wgt. If the LVGO has a sulfur content of 1%, the HVGO a sulfur content of 2%, and the vacuum residue a sulfur content of 3%, then the sulfur value for the HVGO and vacuum residue would be highlighted.

Tip: Use Show Zero-flow and Highlight Off-spec together to understand why particular intermediates are not being blended into final products.

Show zero flow

By default, the Blending > Blend Detail grid only shows the streams, and the properties of these streams, for materials which are in a blended product. A blended product is shown only if at least one of its streams has non-zero flow. You can change these behaviors with the Show Zero-Flow button in the Blend Detail ribbon group. When you press this button, the following two options appear:

• Show Zero-Flow Products: Shows any products which do not receive flow from any streams, and therefore are not produced at all.

• Show Zero-Flow Components: Shows any streams which could be pooled into a product, but are not in the final optimized blended product.

  

For example, low sulfur fuel might be a blended product of LVGO, HVGO and vacuum residue. In the blend solution only LVGO and HVGO are included in the final product. By default, only these two streams and their properties are shown in the Blend Detail Grid. When Show Zero-Flow Components is selected, the HVGO is also included in the Blend Detail.

Tip: You can use the Show Zero Flow option to determine why a particular intermediate stream was not pooled into a product. For example, if you expected that HVGO could be pooled into the low sulfur fuel oil, but the final solution showed that none of this stream was in the finished product, then you could investigate the qualities of the intermediates, and it might be found that the HVGO sulfur was too high to allow it to be pooled in this product.
