Department of Chemical Engg, Bharati Vidyapeeth College of. Abstract. Oil from sandalwood is commonly obtained by a conventional distillation process which requires great energy, significant amount of solvents, and quite a long process time. Therefore, the use of new 'green technique' for extracting essential oil with minimum/low energy, solvents, and time need to be considered. Use of solar energy for cooking and steam generation is quite common around the world. However, use of solar energy for extraction of essential oils from medicinal and aromatic plants has recently been explored and its effects are still largely unknown. The current study is about essential oil extraction. Essential Oil Extraction and Analysis. Essential oil yields from the plant population study were achieved using a pilot-scale 500 liter portable steam distillation unit (Alkire and Simon 1992). The essential oil of catnip is difficult to recover as the oil can elute in two fractions, one lighter and the other heavier than water, requiring. Abstract - In this paper, a plant for the extraction of essential oil from leaves of eucalyptus tree was developed. The extraction plant is made up of a steam generation unit. (boiler), stripping chamber, condenser (heat exchanger), decanter (settler), cooling water system and a pressurized gas burner as heat source. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, absolute oil extraction, resin tapping, and cold pressing. They are used in perfumes, cosmetics, soaps and other products, for flavoring food and drink, and for adding scents to incense and. Extraction of Essential oil from Eucalyptus Leaves as.
