Rahimi CFD research center, Chemical Engineering Department, Razi University, Kermanshah, Iran. 0000-0002-1144-9351 Journal Article 2015 08 03 This paper reports a study to find optimum conditions for oil extraction from vetiver root. For this purpose, the influence of temperature and pressure on the extraction yield is investigated. In addition, the effects of supercritical fluid flow rate and particle diameter on optimum temperature and pressure have been studied. The results show that optimum pressure is a strong function of particle diameter and solvent flow rate. However, the results reveal that the optimum temperature is independent from particle diameter and solvent flow rate. optimization supercritical fluid extraction Vetiver Oil https://www.ijche.com/article_10329_ce128c3e8f0c0ae4b3e843dc7cbab0f7.pdf
