| Summary: | The article is devoted to the analysis of compressibility factor calculation methods
in the temperature range from 220 to 250 K. The AGA8-92DC (GOST 30319.2-
96), AGA8 Report Detail (GOST 30319.3-2015), GERG-2004/2008, NX19, GERG-91,
ISO 20765-1 (GOST R 8.662-2009), GSSSD MR 118-05 (moderately compressed gas
mixtures) and GSSSD MR 113-03 (Wet Oil Gas) methods are experimentally tested.
Deviations of experimental data and calculated values of compressibility coefficient
determined by the specified methods are shown. It is found out that the deviation
of the calculated values of the compressibility factor according to the AGA8-92DC,
AGA8 Report 1 Detail, GERG-2004/2008, ISO 20765-1 (GOST R 8.662-2009), GSSSD
MR 13-03 methods from the experimental ones does not exceed 0,1 %. This fact
confirms the possibility of using these methods in the temperature range from 220 to
250 K. The results obtained in the framework of this study are highly significant for
flow metering, and in particular, provide an increase in the accuracy of the procedure
for bringing the volume of natural gas to standard conditions at low temperatures. |
