Title: Thermophysical properties of fluids for the gas industry. Annual report, January-December 1992

Technical Report ·
OSTI ID:6015664

The US gas industry standard for computing thermophysical properties is the A.G.A. Transmission Measurement Committee Report No. 8 equation of state (AGA 8). The report summarized the results from several experimental, theoretical, and modeling programs directed at the extensive evaluation of the accuracy with which various types of natural gas physical properties can be calculated using AGA 8 and related methods. The most important results were the assembly of benchmark data sets for speed of sound, viscosity, fugacity, heat capacity, critical region PVT, mixture compressibilities, and vapor pressure measurements for natural gas fluids. When tested against these benchmark properties data, the AGA 8 equation of state model was found to be generally accurate within + or - 0.1% for sound speeds (and densities) and within + or - 0.03% for compressibilities over the ranges of pressure, temperature, and composition that encompass the major region of custody transfer for natural gas. Work was also completed on the fabrication and testing of a prototype catalytic cracking detector for the selective detection of hydrocarbons; a US patent was awarded for this invention with the assignment to GRI.
