1、Designation: D3984 08D3984 13Standard Specification forEthane Thermophysical Property Tables1This standard is issued under the fixed designation D3984; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A nu
2、mber 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 ethane are for use in the calculation of the pressure-volume-temperature (PVT),thermodynamic, and
3、transport properties of ethane for process design and operations. Tables are provided for gaseous and liquidethane at temperatures between 92 and 600 K at pressures to 20 MPa. One table providesTwo tables provide properties at theconditions of liquid-vapor equilibrium (saturation properties). The ot
4、herA third table provides properties at selected T,p points forthe equilibrium phase at those conditions. The tables were developed by the National Institute of Standards and Technology froma Standard Reference Database product REFPROP, version 8.0.9.0.1.2 The values stated in SI units are to be reg
5、arded as standard. No other units of measurement are included in this standard.2. Applicability2.1 These tables apply directly only to pure gaseous ethane. However, it is expected that they may find substantial use inmathematical models and tables for the thermophysical properties of mixtures contai
