2、tandard 1942 Revised 2016 GPA Midstream Association Sixty Sixty American Plaza, Suite 700 Tulsa, Oklahoma 74135 GPA Midstream Standard 2145-16 GPA 2145 Page ii FOREWORD This standard provides the gas processing industry with a convenient compilation of authoritative numerical values for hydrocarbons

3、 and other compounds occurring in natural gas and natural gas liquids as well as other compounds of interest to the industry. The physical properties selected are those considered most valuable for engineering and analytical computations. Most properties are based upon two NIST Standard Reference Da

4、tabases: the Web Thermo Tables, WTT (NIST SRSD-3), and the Reference Fluid Thermodynamic and Transport Properties Database, REFPROP 9.1 (NIST SRD-23). The data in this publication were checked, evaluated, and recalculated when necessary by the Applied Chemicals and Materials Division of the Material

5、 Measurement Laboratory at NIST. The listed flammability limits and octane numbers were not evaluated at NIST and sources for these properties are provided in the references. Methodology The process for revising this and future versions of GPA-2145 has been updated. Current values will be used in al

6、l subsequent revisions, except when a newly accepted and confirmed equation of state or substantiated improved measurements becomes available. In these situations, the following items determine when changes will be made. a) If any property for a component falls outside the uncertainty of the new EOS

7、 or substantiated measurements, all properties will be updated for that component. b) If all existing values for a component fall within the uncertainty of the new EOS or substantiated measurements, no changes will be made. Summary of changes in this revision of GPA-2145 a) For helium, all values we

8、re updated based on a new equation of state finalized in 2015. b) For propylene, the heat capacities were updated based on the final equation of state. c) The “volume of air required to burn one volume of gas” has been updated to reflect the revised concentration of oxygen in air (as explained in th

9、e Properties of Air section at the end of this standard). d) The definition of relative density was modified based solely on a fixed reference value (28.9625 g/mol), not on the molar mass of air. e) The main tables now list pure fluids only; all properties for air were removed from the tables and in

10、cluded in the Properties of Air section at the end of this standard. f) All fluids from TP-17 were added, and properties displayed here are based on the format from that version. Most of the properties for the fluids in the 1998 version of TP-17 (excluding the fluids in 2145-09) have changed; the ne

11、w values are based on properties calculated from the equations of state available in the REFPROP program (reference 2) or from the TRC database (reference 3). The main tables and the extended tables list the same properties. g) The fluids in 2145-09 are included here in their original format, as wel

12、l as in the transposed TP-17 format. GPA 2145 Page iii h) Additional properties from TP-17 are included; these are the chemical formula, acentric factor, critical density, compressibility factor at 60 F, liquid net heating value, refractive index, and temperature coefficient of density. i) Other pro

13、perties now appearing in the main tables include the specific volume as an ideal gas, vapor pressure at 60 F, and summation factor for a new compressibility formula. All fluids in the GPSA Engineering Data Book are now included in this revision of GPA-2145. Property values for compounds listed here

14、in GPA 2145-16 supersede those listed in the GPSA Engineering Data Book, 13thedition, and all earlier editions.
