Modeling and optimization of molar volume for the binary systems containing nearcritical and supercritical CO2 applicable to micro and nanoparticles production

摘要

The molar volume of binary systems at high pressures is an important key for production of micro and nanoparticles production. This paper compares two different equations of states of Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) for correlating and optimizing of operating conditions for 20 different binary systems to produce micro and nanoparticles. The effects of the temperature and pressure of binary systems on the molar volume of organic solvents have also been investigated. It is observed that by increasing the pressure of the system at a constant temperature, the molar volume of the liquid phase decreases, while at higher pressures a sudden volume expansion can lead to minimum molar volume of liquid phase and these conditions can be reported as a proper condition in producing micro and nanoparticles.
