Densities of the isopropanolamine-water binary mixture system were measured over the whole range ... more Densities of the isopropanolamine-water binary mixture system were measured over the whole range of compositions at temperatures from 283.15 to 353.15 K using an Anton Paar digital vibrating glass tube densimeter. The density of this system has been found an increasing function of the isopropanolamine composition. Excess molar volume data, calculated from the measured experimental densities, have been correlated using the Redlich-Kister equation. Parameters for the Redlich-Kister equation have been adjusted. Partial molar volumes at infinite dilution have been calculated for each component.

Heat and Mass Transfer

The mass, momentum and energy equations are solved numerically using the finite element method for an evaporator cross section. When a separate vapor region is formed inside the capillary structure, the shape of the free boundary is calculated by satisfying the mass and energy balance conditions at the interface. The superheat limits in the capillary structure are estimated by using the cluster nucleation theory. An explanation is provided for the robustness of LHPs to the boiling limit.

Research paper thumbnail of Solubility measurement and modeling for the system propane-water from 277.62 to 368.16 K

Fluid phase …, Jan 1, 2004

In this communication, a total of 61 new experimental data on the solubility of propane in water ... more In this communication, a total of 61 new experimental data on the solubility of propane in water are reported over a wide temperature range (i.e., 277.62-368.16 K) up to 3.915 MPa (i.e., liquid water-vapor region). A static-analytic apparatus taking advantage of a pneumatic capillary sampler is used for fluid sampling. The Valderrama modification of the Patel-Teja equation of state combining with non-density dependent mixing rules is used for modeling vapor-liquid equilibrium. The new solubility data generated in this work are used for adjusting the binary interaction parameters between propane and water. The experimental data generated in this work are compared to literature data and to the calculations through the thermodynamic model tuned on our experimental data. In order to further evaluate the performance of the thermodynamic model, a comparison is made between the predicted water content data and the experimental data reported in the literature. The predictions are in good agreement with the independent experimental data, demonstrating the reliability of the thermodynamic approach used in this work.
