AB In this work, simulation of supercritical extraction to concentrate minor components from oil deodorizer distillates (ODD) in the commercial software Aspen Plus ® has been investigated. The extraction process consist out of a first extraction column at 313 K and 10 MPa followed by another extraction column at the same temperature and 16 MPa. The RK-Aspen property method was selected for the supercritical extraction process. The solubility of FAME and tocopherol in CO2 was investigated in more detail. This case study provided insights for the complex ODD mixture. Based on these results, on can assume that a supercritical process can be used to isolate tocopherols from the esterified ODD. Further, the complex ODD mixture was used to simulate the isolation of squalene. Literature data for solute/sc-CO2 used to calculate the interaction parameters for the RK-Aspen property method. Three kinds of feedstocks were simulated: sunflower ODD, high and low tocopherol content in soybean ODDs. The highest purity of squalene is achieved using sunflower and low tocopherols content in soybean ODDs, the highest squalene amount using high tocopherols content in soybean ODDs and the highest yield using low tocopherols content in soybean ODDs.
