This specification covers the isobutane thermophysical property tables which are used in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of isobutane for process design and operations. Tables are provided for gaseous and liquid isobutane at temperatures between 135 and 600K at pressures to 35 MPa. These tables apply directly only to pure gaseous and liquid isobutane. However, it is expected that mathematical models and tables shall be useful for the thermophysical properties of mixtures containing isobutane, such as natural gas. These thermophysical property tables are: Thermophysical Properties of Coexisting Gaseous and Liquid Isobutane, in SI units and Thermophysical Properties of Isobutane, along isobars, in SI units.
Keywords:
isobutane, isobutane gas tables, natural gas, thermodynamic properties of isobutane, transport properties of isobutane, 2-methylpropane,, ICS Number Code 75.160.30 (Gaseous fuels)
1. Scope |
1.1 The thermophysical property tables for isobutane are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of isobutane for process design and operations. Two tables provide properties at the conditions of liquid-vapor equilibrium (saturation properties), one for liquid and one for vapor, at temperatures between 120 K and the critical point, 407.81 K. A third table provides properties at selected T, p points for the equilibrium phase at temperatures between 120 K and 570 K at pressures to 20 MPa. The tables were developed using the National Institute of Standards and Technology Standard Reference Database product REFPROP, version 9.1. 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 standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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. |
