The objectives are the determination of comprehensive accurate thermophysical properties data and predictive calculation methods for the major pure components (methane, ethane, propane, butanes, and nitrogen) and selected mixtures of liquefied…
To maintain the integrity and reliability of natural gas transportation systems, system operators ensure that products in transit remain in the gas phase under foreseeable operating conditions. Compliance with pipeline hydrocarbon dew point (HCDP)…
Simplified methods to estimate the hydrocarbon cricondentherm hydrocarbon dewpoint temperature and the associated phase curve are desirable in cases with limited processor power/memory or in cases where full gas composition analysis information is…
The 2017 revision of AGA (American Gas Association) Report #8 encourages adoption of the new GERG2008 EOS (Equation of State) technology but leaves users with the decision on whether to upgrade. Due to the technical complexity of the subject and the…
In order to have an improved understanding of the applicability of standard EOS in pipeline applications, a set of gas physical property tests were undertaken with sweet and sour natural gas and CO2 mixtures at typical pipeline compositions and…
This manual is based on the findings of PAR Research Project NX-19 initiated by the Pipeline Research Committee in 1956 upon the recommendation of the Gas Measurement Committee. The initial purpose was to extend the range of the A.G.A.…
In order to revise the AGA-8 documentation for publication in 2014, better knowledge of the 0.1% uncertainty level in the equation of state is needed. The 0.1% uncertainty level has been identified by an AGA-8 task group as the acceptable limit of…
This monograph consists essentially of two parts. One part reports the results of test, and the other presents correlations of data from the tests. The correlations are designed for computing significant properties of fluids, using data from…
