1、Designation: D3956 07 D3956 12Standard Specification forMethane Thermophysical Property Tables1This standard is issued under the fixed designation D3956; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A

2、number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 The thermophysical property tables for methane are for use in the calculation of the pressure-volume-temperature (PVT),thermodynamic, a

3、nd transport properties of methane for process design and operations. Tables Three tables are provided forgaseous and liquid methane at temperatures between 90 K and 600K at pressures to 20 MPa. One table provides properties at theconditions of 30 MPa. Two tables provide properties for the liquid an

4、d vapor phases at liquid-vapor equilibrium (saturationproperties). The otherthird table provides properties at selected T,p points for the equilibrium phase at those conditions. The tableswere developed by the National Institute of Standards and Technology from a Standard Reference Database product

5、REFPROP,version 7.0.9.0.2. Applicability2.1 These tables apply directly only to pure gaseous methane. However, it is expected that they may find substantial use inmathematical models and tables for the thermophysical properties of mixtures containing methane.3. Tables3.1 Thermophysical Properties of

9、m.24. Additional Information4.1 Reference state properties are required to calculate certain of the thermodynamic properties (enthalpy, entropy, etc.) froman equation of state formulation. The reference state properties used to generate the tables in this specification are: enthalpy, H,and entropy,
