Fractionation of a peel oil key mixture by supercritical CO_2 in a continuous tower

摘要

The fractionation of peel ois with supercritical carbon dioxide was studied using a mixture of four key compounds. Experiments were performed on a 2-m column operated counter corrently. The operating pressure and temperature ranged between 75 and 90 bar and between 40 and 80 Deg C, respectively. Solvent-to-feed ratios of 60, 80, and 120 were used. The total and partial extract Refluxes were tested in order to evaluate the process feasibility.
