A simple thermodynamic model for the solubility of thermolabile solids in supercritical fluids

Solubility Parameter of Fluids from Molecular Thermodynamic Model

The modified square well Potential is combined with perturbed-hard-trimer-chain (PHTC) EOS to predict the solubility parameter of several fluids including alkanes, refrigerants and molten polymers. The performance of the proposed model has been evaluated by predicting the solubility parameter of 12 hydrocarbons,3 refrigerants, and 12 polymers. From the 263 data points for hydrocarbons and refri...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Rutile solubility in supercritical NaAlSi3O8–H2O fluids

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Thermodynamic model for mineral solubility in aqueous fluids: theory, calibration and application to model fluidflow systems

We present a thermodynamic model for mineral dissolution in aqueous fluids at elevated temperatures and pressures, based on intrinsic thermal properties and variations of volumetric properties of the aqueous solvent. The standard thermodynamic properties of mineral dissolution into aqueous fluid consist of two contributions: one from the energy of transformation from the solid to the hydrated-s...
