ASTM D3984-19

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 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 Standard Reference Database 23, REFPROP, version 10.0.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 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.

Overview

ASTM D3984-19: Standard Specification for Ethane Thermophysical Property Tables provides authoritative thermophysical property tables for pure ethane in both gaseous and liquid phases. Developed by ASTM International and based on data from the National Institute of Standards and Technology (NIST) REFPROP database, this standard is essential for professionals involved in process design, operations, and the modeling of natural gas and ethane-containing mixtures. The document ensures that scientific and industrial calculations regarding ethane's pressure-volume-temperature (PVT), thermodynamic, and transport properties are based on accurate, internationally recognized data.

Key Topics

• Scope of Properties: The standard covers ethane properties for temperatures from 92 K to 600 K and pressures up to 20 MPa.
• Data Provided: Tables present properties at equilibrium (liquid-vapor saturation) and at selected temperature-pressure (T, p) points for both phases.
• Thermophysical Properties: Included properties are:
  • Molar density
  • Molar enthalpy
  • Molar entropy
  • Heat capacities (at constant volume and pressure)
  • Speed of sound
  • Viscosity
  • Thermal conductivity
• Reference State: Calculations are based on reference enthalpy and entropy at ethane's normal boiling point (184.57 K, 0.10133 MPa).
• SI Units: All tabulated data are provided in SI units for global consistency.

Applications

ASTM D3984-19 is practically valuable in various sectors, including:

• Natural Gas Processing: Enables accurate PVT and thermodynamic calculations for ethane, supporting design and simulation of gas separation, liquefaction, and purification systems.
• Mixture Modeling: Foundation for developing extended property tables and mathematical models for natural gas and hydrocarbon mixtures containing ethane.
• Process Simulation: Facilitates reliable inputs for simulation software, enhancing the reliability of chemical engineering and process design calculations.
• Transport and Storage: Supports the engineering of transport pipeline systems and storage vessels by providing critical thermophysical and transport property data.
• Academic Research: Supplies validated data sets necessary for physical chemistry, thermodynamics, and engineering studies involving gaseous and liquid ethane behavior.

Practical Value

The adoption of ASTM D3984-19 ensures:

• Accuracy and Consistency: Users benefit from standardized, rigorously validated ethane property data recognized internationally.
• Operational Efficiency: Reliable PVT and transport property data helps optimize process design, safety, and system performance in industrial settings.
• Regulatory Compliance: Aligns with international trade and technical barrier regulations, supporting global commerce and industry interoperability.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D3984 − 13 D3984 − 19
Standard Specification for
Ethane Thermophysical Property Tables
This standard is issued under the fixed designation D3984; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 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 92 and 600 K at pressures to 20 MPa. 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 product23, REFPROP, version 9.0.10.0.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.
2. Applicability
2.1 These tables apply directly only to pure gaseous ethane. However, it is expected that they may find substantial use in
mathematical models and tables for the thermophysical properties of mixtures containing ethane.
3. Tables
3.1 These tables were produced by equations from a computer package, “NIST Standard Reference Database 23; Reference
Fluid Thermodynamic and Transport Properties Database (REFPROP): Version 9.0.”10.0.” A wide selection of units (SI units,
engineering units, chemical units) and additional properties are available with this program.
3.2 These thermophysical property tables are:
3.2.1 Thermophysical Properties of Ethane Liquid at Vapor-Liquid Equilibrium, in SI units. See Table 1.
3.2.2 Thermophysical Properties of Ethane Vapor at Vapor-Liquid Equilibrium, in SI units. See Table 2.
3.2.3 Thermophysical Properties of Ethane Along Isobars, in SI units. See Table 3.

4. Additional Information
4.1 Reference state properties are required to calculate certain of the thermodynamic properties (enthalpy, entropy, etc.) from
an equation of state formulation. The reference state properties used to generate the tables in this specification are: enthalpy, H,
and entropy, S, at the Normal Boiling Point; 184.57K184.57 K and 0.10133MPa0.10133 MPa (H = 14716 J/mol and S = 79.731
J/(mol K)). The molar mass of ethane is 30.069 g/mol.
