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.
Область применения1.1 The thermophysical property tables for ethane 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 92 and 600 K at pressures to 20 MPa. Two tables provide properties at the conditions of liquid-vapor equilibrium (saturation properties). A third table provides properties at selected T, p points for the equilibrium phase at those conditions. The tables were developed by the National Institute of Standards and Technology from a Standard Reference Database product REFPROP, version 9.0.
