In this work, a simulation procedure of this process was developed through the use of the commercial simulator ASPEN PLUS, using the operating conditions typical of the supercritical extraction process. As case study, the recovery and purification of acrylic acid obtained from sugar cane fermentation will be considered. As supercritical solvent, carbon dioxide was used. This example characterizes the exploitation of renewable sources of the biomass. This is very interesting because the supercritical extraction is a clean technology and the acrylic acid can be obtained from biotechnological process. The optimization procedure was carried out analyzing the variables involved in the process.
