1、Designation: D 3984 08Standard 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 revision. A number i
2、n 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 foruse in the calculation of the pressure-volume-temperature(PVT), thermodynamic, and transpo
3、rt properties of ethane forprocess design and operations. Tables are provided for gaseousand liquid ethane at temperatures between 92 and 600 K atpressures to 20 MPa. One table provides properties at theconditions of liquid-vapor equilibrium (saturation properties).The other table provides propertie
4、s at selected T, p points forthe 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 8.0.1.2 The values stated in SI units are to be regarded asstandard. No other units of me
5、asurement are included in thisstandard.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 prop-erties of mixtures containing ethane.3. Tables3.1 These thermophy
