8.2.10 Volume Correction Factor - VCF
L00-NXA82xxx-16-00-00-xx-102
8.2.11 Sediment and Water
L00-NXA82xxx-16-00-00-xx-103
• Some products have entrained (suspended) sediment and water (S&W)
– i.e. crude’s
• S&W is determined from sample by laboratory method ("Karl-Fisher"-method). The
Sediment and Water percentage (S&W%) determined with the sample is transferred in the
Sediment and Water Fraction (SWF). A correction factor for the product is determined.
As second result the Sediment and Water Volume can be calculated.
Sediment & Water calculation methods
There are 6 methods to calculate S&W
1. SWV = 0
2. SWV = TOV x SWF
3. SWV = (TOV - FWV) x SWF
4. SWV = {(TOV - FWV) x CTSh} x SWF
5. SWV = GOV x SWF
6. SWV = GSV x SWF ("standard" or "default" method)
Where the sediment and water fraction (SWF) is:
L00-NXA82xxx-16-00-00-xx-058
8.2.12 Net Standard Volume - NSV
L00-NXA82xxx-16-00-00-xx-104
Net Standard Volume is calculated like follows:
• Starting from GOV
• Multiply by the Volume Correction Factor and
• Multiply by the S&W correction factor
