Rapid Expansion of Supercritical Solutions (RESS): The RESS process explores variations in solvency of the fluid with the pressure changes and consists in expanding the solution (solute dissolved in supercritical fluid) to ambient conditions of temperature and pressure leading to decrease in solvent power and consequent solute precipitation due to supersaturation of the solution caused by a significantly decrease in solvent density Jung and Perrut (2001).
