Override specific gravity for non-liquid streams

You can automatically create an override for the specific gravity of a non-liquid stream using the following formula:

Specific gravity = NLFE/SRF/StreamCalorificValue

where:

• NLFE is the Non-Liquid Fuel Equivalent calorific value, defined in the Details page.

• SRF is the Standard Refinery Fuel calorific value, also defined in the Details page.

• StreamCalorificValue is the calorific value for the stream. It must be defined in the data grid using TSRF/T as unit of measure.

To add the override, follow these steps:

1. Right click on the specific gravity row for the stream.

2. Choose Create Automatic NLFE Override for Row from the menu.

The override is created, and you can then view and modify it like any other override, by right clicking on the row and choosing Edit Offset/Override for Row from the menu.

Note that another override is created for the volume-based yield of the stream, to take into account the new specific gravity, using the following formula:

Gas yield = OriginalValue * OriginalSPG / StreamSPG

where:

• OriginalValue is the yield before the override.

• OriginalSPG is the specific gravity before the override.

• StreamSPG is the specific gravity after the override.
