Description / Abstract:


This standard covers density and volume correction factors for blends of denatured ethanol and gasoline blend components ranging from 0 % to 95 % denatured ethanol based upon calculation methods defined in API MPMS Chapter 11.1 and Chapter 11.3.3. Calculation of blends and denatured ethanol containing more than 95 % ethanol should use the calculation procedures within API MPMS Chapter 11.3.3.

The standard consists of correlations and algorithms for estimating the blend volume change at base conditions and for calculating volume correction factors of denatured ethanol and gasoline component blends. This standard also provides the algorithms to estimate certain blend properties in blending situations where some of the required parameters are not measured.

Range of Applicability

This standard is applicable to blends containing denatured ethanol and gasoline blend components with 15.5 °C (60 °F) densities ranging from 680 to 800 kg/m3 (45.2 to 76.4 °API) containing between 0 % and 95 % by volume denatured ethanol over the temperature range of –40 °C to 50 °C (–40 °F to 122 °F) and pressure range of 0 to 10.34 MPa gage (0 to 1508 psig).
