The Table of Physical Properties for Hydrocarbons and Other Components of Interest to the NaturalGas Industry, GPA Publication Standard 2145, provides the gas processing industry with a convenientcompilation of authoritative numerical values for the paraffin hydrocarbons and other compoundsoccurring in natural gas and natural gas liquids as well as for a few other compounds of interest to theindustry. The physical properties selected are those considered most valuable for engineering andanalytical computations in gas processing plants and laboratories. Most properties are based upon twoNIST Standard Reference Databases: the Web Thermo Tables, WTT, (NIST SRSD-3) and theReference Fluid Thermodynamic and Transport Properties Database, REFPROP, (NIST SRD-23). Thedata in this publication were checked, evaluated, and recalculated when necessary by Robert Chiricoand Eric Lemmon of the Physical and Chemical Properties Division of the Chemical Science andTechnology Laboratory at NIST in Boulder, Colorado. The listed flammability limits and octanenumbers were not evaluated at NIST and sources for these properties are provided in the references.
Some of the listed values result from other values in the tables by simple calculation. Numbers obtainedfrom such related data may differ from the tabulated values in the last digit because of numerical roundoff, but the differences are within the standard uncertainty of the data. The value of the gas constantused in the tables is 8.314472 J/(K*mol). Numerous values were updated from the previous edition ofGPA-2145 to provide full thermodynamic consistency between properties. This was accomplishedthrough consistent use of properties derived with the equations of state underlying the NIST REFPROPdatabase. Properties derived with these equations of state are inherently consistent. This publicationrepresents the first time for which thermodynamic consistency is assured for all properties listed in GPA-2145. Required enthalpies of combustion at 298.15 K were taken from the NIST Web Thermo Tables(WTT). These enthalpies of combustion are reprinted in the notes of this document. All adjustments ofthese values to the selected temperatures of GPA-2145 were completed using consistent thermophysicalproperty values from the NIST REFPROP program.
The values of the physical properties for the components in GPA 2145, as well as those for many morecompounds, appear in the GPSA Engineering Data Book. Property values for compounds listed here inGPA 2145-09 supersede those listed in the GPSA Engineering Data Book. For components not listed inGPA 2145, the property values in GPA TP-17 may be used.
