Table
Description
ASTM1250-
1980 Table 59E
This table provides density at 20 C 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 20 F is unknown
 Reference Temperature is 20 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 20 C are for informational purposes and will not be used in
calculations during operations.
The CTL value is calculated as CTL = Observed Density / Corrected Density at 20 C.

This table provides density at 20 C of light hydrocarbons at observed temperature and
density
ASTM1250-
1980 Table
901A
This is the table-based volume-correction for Alcohols/Biofuels (Brazil) Reference
Standard:ABNT NBR 5992 for Ethanol (901A) It is passed the product api density20 at 60
degrees (api60) and the product temperature in degrees F
Table TEC
This table provides CTL factors for correcting volumes of ethanol at observed temperatures
to the volume at either 15 C or 60 F. Use this table if the following conditions exist:
 The liquid is ethanol
 Coefficient of expansion at 15 C or 60 F is known
 Reference Temperature is 15 C or 60 F
After selecting this table, enter the coefficient of expansion of the liquid at 15 C or 60 F.
Test temperatures can be entered on this screen that will calculate a CTL based on the test
temperature and coefficient of expansion. 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 ethanol at observed temperatures
to the volume at either 15 C or 60 F. Use this table if the following conditions exist:
 The liquid is ethanol
 Coefficient of expansion at 15 C or 60 F is not known
 Reference Temperature is 15 C or 60 F
Test temperatures can be entered on this screen that will calculate a CTL based on the test
temperature and coefficient of expansion. The test temperature and Calculated CTL are for
informational purposes and will not be used in calculations during operations.
Table TEC ETH
B100
This table provides CTL factors for correcting volumes of ethanol at observed temperatures
to the volume at either 15 C or 60 F. Use this table if the following conditions exist:
 The liquid is ethanol
 Coefficient of expansion at 15 C or 60 F is not known
 Reference Temperature is 15 C or 60 F (needs to be maintained under component level!)
Coefficient of Density is fixed at 0.84*10E-3
Test temperatures can be entered on this screen that will calculate a CTL based on the test
temperature and coefficient of expansion. The test temperature and Calculated CTL are for
informational purposes and will not be used in calculations during operations.
Note: Blend range from B0 to B100
