Isobutane: provisional thermodynamic functions from 114 to 700/sup 0/K at pressures to 700 bar

Technical Report ·
OSTI ID:5558675

Isobutane not only is a component of liquefied natural gas (LNG), but also may become an important heat-exchange fluid for geothermal cycles. The present report is fifth in a series on the pure component of LNG, namely methane, ethane, propane, n-butane, and isobutane. Thermophysical properties of isobutane are tabulated at integral temperatures along isobars over the entire range of fluid states. Results for the compressed liquid, from the triple- to the boiling-point, have been estimated by use of the highly constrained, nonanalytic equation of state, because experimental P-rho-T data are lacking in this region.
