Abstract :
The solubility of CO2 in various solvents in the binary systems at high pressures is an important key for production of micro and nanoparticles production. This paper compares three different equations of state of Peng-Robinson (PR), Soave-Redlich-Kwong (SRK) and Statistical Associating Fluid Theory (SAFT) for correlating of CO2 solubility in the 20 different binary systems at high pressures applicable to micro and nanoparticles production. The effects of the temperature and pressure of binary systems on the solubility of CO2 in organic solvents have also been investigated. It is observed that the solubility of CO2 in solvents increases with the increase in the pressure at the same temperature. At higher pressures the liquid phase is mostly CO2 and these conditions are interested in supercritical fluid processes.
