This table is used to correct observed density at the observed temperature to a density at
15ï‚° C. When this table is activated, the corrected density is then automatically used in Table
54B, which provides CTL factors for correcting volumes of gasolines at observed
temperatures to the volume at 15ï‚° C. Use this table if the following conditions exist.
ï‚· The liquid is a lube oil
ï‚· Observed Density is to be corrected to 15ï‚° C and used in Table 54B
ï‚· Reference Temperature is 15ï‚° C
After selecting this table, enter the Density of the liquid at the observed temperature. The
valid range of Density is from 800-1064 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 density at 15ï‚° C of light hydrocarbons at observed temperature and
density. Use this table if the following conditions exist.
ï‚· The liquid is a NGL or LPG (propane)
ï‚· Current Temperature and Density is available.
ï‚· Density at 15ï‚° C is unknown
ï‚· Reference Temperature is 15ï‚° C
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 60ï‚° 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 is used to correct observed density at the observed temperature to a density at
20ï‚° C. When this table is activated, the corrected density is then automatically used in Table
54B, which provides CTL factors for correcting volumes of gasolines at observed
temperatures to the volume at 20ï‚° C. Use this table if the following conditions exist.
ï‚· The liquid is crude oil
ï‚· Observed Density is to be corrected to 20ï‚° C and used in Table 54B
ï‚· Reference Temperature is 20ï‚° C
After selecting this table, enter the Density of the liquid at the observed temperature. 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 is used to correct observed density at the observed temperature to a density at
20ï‚° C. When this table is activated, the corrected density is then automatically used in Table
54B, which provides CTL factors for correcting volumes of gasolines at observed
temperatures to the volume at 20ï‚° C. Use this table if the following conditions exist.
ï‚· The liquid is a refined product
ï‚· Observed Density is to be corrected to 20ï‚° C and used in Table 54B
ï‚· Reference Temperature is 20ï‚° C
After selecting this table, enter the Density of the liquid at the observed temperature. 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.
