API MPMS Chapter 11.3.3 PDF
This standard covers density and volume correction factors for denatured fuel ethanol. Annex E of the Third Edition presents a method to determine the compressibility factor for ethanol. The actual standard consists of the explicit implementation procedures set forth in this document. Sample tables and other examples created from a computerized version of this implementation procedure are presented as examples only, and do not represent the standard.
This standard is applicable at any operating temperature to bulk (e.g. tank trucks, tank cargos, barges) denatured 95 % to 99 % fuel ethanol containing D4806 allowed denaturants (natural gasoline, gasoline blend stocks, and unleaded gasoline) and denatured 99+ % fuel ethanol containing less than 1 % denaturant. This standard does not apply to undenatured ethanol of any purity. Annex E extends the range of application to –40 to 60 °C (–40 to 140 °F) over the pressure range of 0 to 15 MPa (0 to 2200 psi).
