1、Designation: D 3956 07Standard Specification forMethane Thermophysical Property Tables1This standard is issued under the fixed designation D 3956; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、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 thermophysical property tables for methane are foruse in the calculation of the pressure-volume-temperature(PVT), thermodynamic, and tran
3、sport properties of methanefor process design and operations. Tables are provided forgaseous and liquid methane at temperatures between 90 K and600K at pressures to 20 MPa. One table provides properties atthe conditions of liquid-vapor equilibrium (saturation proper-ties). The other table provides p
4、roperties at selected T, p pointsfor the equilibrium phase at those conditions. The tables weredeveloped by the National Institute of Standards and Technol-ogy from a Standard Reference Database product REFPROP,version 7.0.2. Applicability2.1 These tables apply directly only to pure gaseous meth-ane
5、. However, it is expected that they may find substantial usein mathematical models and tables for the thermophysicalproperties of mixtures containing methane.3.
