摘要: Abstract Supercritical carbon dioxide (SCCO 2 ) separation of essential oil and seed in citrus processing residues was investigated taking d -limonene canola as model compounds, respectively, a continuous countercurrent column. The effect temperature pressure on the recovery from top extraction column investigated. Temperature gradient along also applied to achieve more effective separation. At isobaric condition (10 MPa), highest enrichment extract could be obtained at 60 °C. However, found 30 °C. Evaluation performance this proposed process carried out by calculation mass transfer correlation coefficient, theoretical number stages solubility components SCCO .
