(Specification)Standard Specification for Ethane Thermophysical Property Tables
Standard Specification for Ethane Thermophysical Property Tables
ABSTRACT
This specification establishes the formulation of ethane thermophysical property tables for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of gaseous and liquid ethane for process design and operations. This table will be substantially useful in mathematical models and tables for the thermophysical properties of mixtures containing ethane, such as natural gas.
SCOPE
1.1 The ethane thermophysical property tables are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of ethane for process design and operations. Tables are provided for gaseous and liquid ethane at temperatures between 90 and 600K at pressures to 70 MPa. These tables were developed by the National Institute of Standards and Technology (formerly the National Bureau of Standards) upon culmination of four years of effort in acquiring available physical properties data, in performing experimental measurements, and in formulating these tables for use in thermal computations.
