1、Designation: D 3984 93 (Reapproved 2003)Standard Specification forEthane Thermophysical Property Tables1This standard is issued under the fixed designation D 3984; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last re
2、vision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 The ethane thermophysical property tables are for use inthe calculation of the pressure-volume-temperature (PVT),thermodynam
3、ic, and transport properties of ethane for processdesign and operations. Tables are provided for gaseous andliquid ethane at temperatures between 90 and 600K at pres-sures to 70 MPa. These tables were developed by the NationalInstitute of Standards and Technology (formerly the NationalBureau of Stan
4、dards) upon culmination of four years of effortin acquiring available physical properties data, in performingexperimental measurements, and in formulating these tablesfor use in thermal computations.2. Sponsorship2.1 The preparation of the tables and supporting work wasdone by the National Institute
5、 of Standards and Technology(NIST) under the sponsorship of the Gas Research Institute, theAmerican Gas Association, and the Standard Reference DataProgram of NIST.3. Applicability3.1 These tables apply directly only to pure gaseous andliquid ethane. However, it is expected that they will findsubsta
6、ntial use in mathematical models and tables for thethermophysical properties of mixtures containing ethane, suchas natural gas.4. Tables4.1 These thermophysical property tables2are:4.1.1 Thermophysical Properties of Coexisting Gaseous andLiquid Ethane, in SI units (Table in Appendix F, pp. 642643).3
7、4.1.2 Thermophysical Properties of Ethane, along isobars,in SI units (Table in Appendix F, pp. 645684).34.2 These tables were produced by equations from a com-puter package, “NIST Thermophysical Properties of FluidsDatabase 12” (also designated MIPROPS) of the StandardReference Data Program of NIST.
8、4A wide selection of units(SI units, engineering units, chemical units) is available withthis program.5. Additional Information5.1 These tables were originally published by the AmericanChemical Society and the American Institute of Physics for theNational Institute of Standards and Technology in a c
9、ompre-hensive report titled “Thermophysical Properties of Fluids. II.Methane, Ethane, Propane, Isobutane and Normal Butane.”5This report also contains the following:5.1.1 Properties and uncertainties data.5.1.2 Correlation equations for ethane.5.1.3 Description of the research study culminating in t
