Recently,

The removal of water from carbon dioxide prior to pipelining to prevent the formation of a condensed phase at elevated pressures relies upon the properties shown in TP

    7、al condition; and performing an expansion of the sample into a previously evacauted secondary cell volume. A series of such isochoric runs coupled with isothermal expansions, typically at the highest temperature, constitute a B-I surface run. An important feature of the B-l method is that it generat

    8、es an entire P-p-T surface with one filling of the sample; hence, for mixtures there is no need to duplicate a composition. Being the only two observables in the B-I experiment, the pressure and temperature are measured with exterme accuracy and precision. Pressure measurements are accurate to 0.01%

    9、 and precise to 0.001%, whereas the temperatures are accurate to 10 mK with a precision of 5 mK or better. DATA REDUCTION TO ENERGY FUNCTIONS Analysis of the measured pressures and temperatures for a B-I surface run provides the densities and compressibilitics. However, for systems for which adsorpt

GPA TP-14 87 3824699 0011452 i156 H 3 Such was the case for the present COi-HzO mixtures and the data were corrected as described in detail by Patel 114. Once these corrections have been made and the densities

    11、and cornpressibilities determined, calculation of the thermodynamic properties is achieved through the use of residual properties. A residual property is defined as the real fluid property value less the perfect gas state property value. Of the various forms of such property changes discussed by Hal

    12、l et al. Id, the one discussed here is the real fluid property at the temperature and density of the fluid less the perfect gas property at a reference temperature, Tref, and reference pressure, Pref. Thus, for a property M, the residual property is defined as where the * indicates the hypothetical
