This report summarizes the results of work performed under DOE/NETL Interagency Agreement DE- FE0003931, which began in October 2011 and ended (after a 6-month no-cost extension) March 31, 2015. The key objectives for this work were to: (1) Measure the dew

Thermodynamic Properties of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone: Vapor Pressure, (p, ?, T) Behavior, and Speed of Sound Measurements, and Equation of State

We report comprehensive thermodynamic property measurements of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone. The p–ρ–T behavior was measured from T = (225 to 470) K with pressures up to 36 MPa using a two-sinker densimeter. These

This article summarizes the correlation procedures developed for IUPAC Project 2012-040-1-100 (Reference correlations for the thermal conductivity and viscosity of fluids over extended range of conditions (vapor, liquid and supercritical region)). This

Reference Correlation of the Thermal Conductivity of o-Xylene, m-Xylene, p-Xylene, and Ethylbenzene from the Triple Point to 700 K and Moderate Pressures

The thermophysical properties of carbon dioxide are essential for accurate process design and optimization. While the thermodynamic properties of CO2 are available with excellent accuracy from the reference-quality equation of state of Span and Wagner, the
