A simulation of citrus oil adsorption separation in the supercritical carbon dioxide

摘要

Aspen Adsim was used to simulate the fractionation of citrus oil with extraction and adsorption combined method in supercritical carbon dioxide.The dynamic behavior in a isothemal and adiabatic bed could be described succesfully,and the simulation results agreed with the experimental data.The effect of adsorption time,the flow rate of feed on the concentration of components in product and the recovery were studied.The amount of loading composition on the adsorbents changed with adsorption time and axial distance of bed was also investigated.
