Description
This table provides density at 60 F of light hydrocarbons at observed temperature and
density. Use this table if the following conditions exist.
The liquid is a NGL or LPG (propane)
Current Temperature and Density is available.
Relative Density at 60 F is unknown
Reference Temperature is 60 F
Test temperatures and densities can be entered on this screen that will calculate the
corrected density at the test temperature and density. The test temperature, density and
Calculated corrected density at 60 F are for informational purposes and will not be used in
calculations during operations.
Note: This table will not produce a CTL value, but this table may be used by other tables
This table provides the relative density of a petroleum product at observed temperature and
density. This table allows specifying the commodity being measured, the reference
temperature, and the units of measure for density, pressure, and temperature.
This table provides CTL factors for correcting volumes of crude oil at observed
temperatures to the volume at 15 C. Use this table if the following conditions exist.
The liquid is crude oil
Density at 15 C is known
Reference Temperature is 15 C
After selecting this table, enter the Density of the liquid at 15 C. The valid range of Density
is from 610-1075 kg/m3. Test temperatures can be entered on this screen that will calculate
a CTL based on the test temperature and the Density. The test temperature and Calculated
CTL are for informational purposes and will not be used in calculations during operations.
This table provides CTL factors for correcting volumes of gasolines at observed
temperatures to the volume at 15 C. Use this table if the following conditions exist.
The liquid is a refined product
Density at 15 C is known
Reference Temperature is 15 C
After selecting this table, enter the Density of the liquid at 15 C. The valid range of Density
is from 653-1075 kg/m3. Test temperatures can be entered on this screen that will calculate
a CTL based on the test temperature and the Density. The test temperature and Calculated
CTL are for informational purposes and will not be used in calculations during operations.
This table provides CTL factors for correcting volumes of petroleum liquids at observed
temperatures to the volume at 15 C. Use this table if the following conditions exist.
The liquid is a refined product or crude oil
Coefficient of Expansion @ 15 C is known
Reference Temperature is 15 C
After selecting this table, enter the Coefficient of Thermal Expansion (alpha) of the liquid at
15 C. The valid range of alpha is from 0.000486-0.001674. The alpha will be entered as
486-1674, however. Test temperatures can be entered on this screen that will calculate a
CTL based on the test temperature and the alpha. The test temperature and Calculated
CTL are for informational purposes and will not be used in calculations during operations.
