GPA 8173-17
Standard for Converting Mass of Natural Gas Liquids and Vapors to Equivalent Liquid Volumes
standard by GPA Midstream Association, 05/01/2017
Full Description
GPA 8173-17 prescribes a method for calculating liquid volumes at equilibrium pressures and at temperatures of 60 F, 15 C, and 20 C from the mass of a natural gas fluid (liquid or vapor) measured at operating conditions, in conjunction with a representative compositional analysis and published values for each component's molar mass and absolute density.
