摘要

Natural gas compressibility factor data which are consistent with new pressurevolume temperature (PVT) reference data have been used to determine the uncertainty of the DETAIL and GROSS characterization methods which are outlined in the 2nd edition of American Gas Association (AGA) Report No. 8 as well as International Standards Organization (ISO) 12213. Inside the custody transfer region (0-12 MPa and 265-335 K), both methods show uncertainties in the compressibility factor of less than 0.1% for unblended natural gases. This is within the experimental uncertainty of the best available data. For natural gas mixtures outside the custody transfer region (0-30 MPa), the DETAIL method generally predicts compressibility factors with an uncertainty of less than 0.1%.
