4 Implementation Procedures 4.1 Denatured 99+ % Fuel Ethanol For volume or density correction from observed temperature to 60 °F, the implementation procedure given in API MPMS Ch. 11.1-2004 shall be used for denatured 99 % fuel ethanol. Denatured 99+ % fuel ethanol is considered to be a “special application” (formerly known as Table 6C or Table 54C) with an alpha coefficient of 0.000599 °F or 0.001078 °C (Annex A). If the observed conditions are at elevated pressure, then a CPL for the liquid should be calculated according to the procedures outlined in Annex E and a combined CTPL should be applied to correct the observed density or volume to 60 °F and standard atmospheric pressure. EXAMPLE A container is determined to have a GOV of 10,000 gallons of denatured 99+ % fuel ethanol at an observed temperature of 85 °F at zero gauge pressure. What is the volume at 60 °F? API MPMS Ch. 11.1-2004, Section 11.1.6.1 applies since there is no pressure correction required. It returns a VCF of 0.98496 for inputs of 85 °F and an alpha of 0.000599 °F. From API MPMS Ch. 12.1.1: GSV = GOV ´ VCF = 10,000 gal ´ 0.98496 = 9850 gal EXAMPLE A container is determined to have a GOV of 10,000 liters of denatured 99+ % fuel ethanol at an observed temperature of 30 °C at zero gauge pressure. What is the volume at 15 °C?4.3 Pressure Correction of Fuel Ethanol For volume correction of fuel ethanol being transferred at elevated pressures, the compressibility of the fuel ethanol should be considered. The experimental program for development of the temperature correction factors did not account for elevated pressures, so no independent data for fuel ethanol exist to demonstrate the differences between fuel ethanol and reagent grade at the denaturant concentrations considered by this standard. Annex E was developed based upon reagent grade ethanol and should be used for applications where pressure corrections are applied. Annex E provides calculation methods for determining the pressure correction factor, CPL, for fuel ethanol. Sections 4.1 and 4.2 provide methods for determining the temperature correction factor, CTL, for fuel ethanol. Taken together the overall volume correction factor, VCF, or correction for temperature and pressure, CTPL, is the product of CTL x CPL. 5 Rounding 5.1 Data Level API MPMS Ch. 12 governs all rounding. As API MPMS Ch. 12.1.1-2012 states, rounding is influenced by the source of the data. For example, if a container’s capacity tables are in whole gallons then all subsequent gallon values should be recorded accordingly. In those cases where there are no other limiting factors (i.e. specific direction by API MPMS Ch. 12 for ethanols), the operator should be guided by Table 1, which is intended for application to bulk liquid quantities. Other considerations may apply for smaller quantities; e.g. while Table 1 recommends the calculated weight of a bulk cargo (say a barge of asphalt) be rounded to whole pounds or kilograms, a user may wish to calculate the weight of a barrel of product to two or three decimal places. The significant digits in Table 1 provide consistency within this standard and may differ slightly from API MPMS Ch. 12.1.1-2012 Table 1. 5.2 Rounding of Numbers Chain calculations should be performed without rounding or truncation. When a calculation result is to be rounded to a specific number of decimals, it shall always be rounded off in one step to the number of figures to be recorded and not rounded in two or more successive steps. When the figure to the right of the last place to be retained is less than five, the figure in the last place retained should be unchanged. When figure to the right of the last place to be retained is five to nine, the figure in the last place should be increased by one.
