Abstract

Essential oils are featured products in global market due its many applications in food and chemical factory and different medicine areas. One of the phenomena accountable for the loss of essential oils quality might be associated with terpene hydrocarbons degradation by oxidation when exposed to air or light, causing disagreeable odors. The procedure of terpenes content reducing, known as deterpenation, can be performed by diverse techniques, among which the liquid-liquid extraction can be highlighted because of its advantages, once that this process can be operated without the use of heating and pressure changes, causing low impact on the essential oil sensory properties and low energy consumption. The development of essential oils deterpenation technology in continuous equipment, which permits the application on industrial scale, has a great value. Thus, this thesis project aims to conduct an experimental study of citrus essential oils deterpenation process in a perforated rotating disc contactor (PRDC) using solutions composed by ethanol with different contents of water as solvents. The column will be operated continuously and in countercurrent under local conditions of temperature and pressure. Once phase equilibrium study is crucial for processes based on the contact between phases, the experimental study of liquid-liquid equilibrium of systems composed of raw citrus essential oils (orange - Citrus sinensis and lime - Citrus aurantifolia) and alcoholic solvents at 25 °C will be also proposed, and this work stage will be based on the study of the process in continuous equipment. The composition of the equilibrium phases will be calculated by using binary interaction parameters relating to NRTL and UNIQUAC thermodynamic models. For the systems containing crude orange essential oil, the binary parameters will be obtained by fitting of the phase equilibrium database available in the Research Group (being part of these experimental data previously determined during the development of the dissertation project, FAPESP project No. 2010/13286-1, and part determined in the doctorate degree project). Concerning to the systems containing raw lime essential oil, the phase equilibrium calculations will be tested with parameter sets from the literature, as suggested by Koshima et al. (2012).Along with the phase equilibrium study and the deterpenation process in continuous equipment, studies relating to the physical properties of the phases will be conducted as well. Indeed, the objective is to monitor values of density, viscosity, surface tension and interfacial tension of the phases and arising streams from the extraction column. It is important to place that this research project is inserted in the Research Support funded by FAPESP (2011/02476-7), entitled "Essential Oils deterpenation by Liquid-Liquid Extraction: Experimental study and process simulation", coordinated by this proposal advisor.
