ACCURATE ENTHALPIES FROM BURNETT-ISOCHORIC DENSITY DATA. Academic Article

abstract

• The Burnett-isochoric PVT experiment is shown to allow direct estimation of the isothermal deviation of enthalpy with pressure for fluids without resort to crossplots versus temperature. Advantage is taken of the equal spacing of Burnett-isothermal data in the logarithm of density. Enthalpies calculated from Burnett-isochoric data for ethane of 0. 03% accuracy are thought to be accurate of 0. 09% whereas calculations with conventional PVT of the same accuracy would yield enthalpies of about 0. 3% accuracy. Enthalpy deviations can be found at low pressures where direct measurement via flow calorimetry is not feasible.
