D03.08 - Thermophysical Properties

ABSTRACT
This specification presents the thermophysical property tables for methane, which are used in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of methane for process design and operations. Tables are provided for gaseous and liquid methane at specified temperature and pressure ranges. One table provides properties at the conditions of liquid-vapor equilibrium (saturation properties). The other table provides properties at selected T, p points for the equilibrium phase at those conditions. These tables apply directly only to pure gaseous methane, but are expected to be substantially useful in mathematical models and tables for the thermophysical properties of mixtures containing methane.
SCOPE
1.1 The thermophysical property tables for methane are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of methane for process design and operations. Three tables are provided for gaseous and liquid methane at temperatures between 90 K and 600 K at pressures to 30 MPa. Two tables provide properties for the liquid and vapor phases at liquid-vapor equilibrium (saturation properties). The 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 10.02.  
1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This standard covers LNG density calculation models  for use in the calculation or prediction of the densities of saturated LNG mixtures from 90 to 120K to within 0.1% of true values given the pressure, temperature, and composition of the mixture.
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
