Experimental study of water (micro) droplets formation from its saturated solution in supercritical carbon dioxide

The formation of water droplets of micron size in supercritical carbon dioxide (SC-CO2) in high-pressure cell with sapphire windows is studied experimentally using in situ laser diffractometry. According to the analysis of diffraction patterns of laser radiation scattered on water droplets in SC-CO2 and optical microscopy data at 10.0 MPa and 40 °C, the mean diameter of water droplets is 55±3 mm.

Key words: supercritical carbon dioxide, extraction, solubility, water droplets, diffraction pattern, diameter of the water droplets
