“…In this case, more than 90% of the recovered oil was extracted in the second stage (at optimal steam flow rate of 2.1 mL/min). The sigmoid curve was also observed in previous studies regarding the kinetics of the distillation of rosemary [29] and Artisica judaica L. essential oil [30]. Furthermore, it was reported that essential oil also followed three different phases: the equilibrium phase, the intermediate transition phase, and the diffusion phase [31].…”

Pomelo peel-derived essential oils have been gaining popularity due to greater demand for stress relief therapy or hair care therapy. In this study, we first performed optimization of parameters in the pomelo essential oil extraction process on a pilot scale to gain better insights for application in larger scale production. Then extraction kinetics, activation energy, thermodynamics, and essential oil quality during the extraction process were investigated during the steam distillation process. Three experimental conditions including material mass, steam flow rate, and extraction time were taken into consideration in response surface methodology (RSM) optimization. The optimal conditions were found as follows: sample weight of 422 g for one distillation batch, steam flow rate of 2.16 mL/min and extraction time of 106 min with the coefficient of determination R2 of 0.9812. The nonlinear kinetics demonstrated the compatibility of the kinetic model with simultaneous washing and unhindered diffusion with a washing rate constant of 0.1515 min−1 and a diffusion rate constant of 0.0236 min−1. The activation energy of the washing and diffusion process was 167.43 kJ.mol−1 and 96.25 kJ.mol−1, respectively. The thermodynamic value obtained at the ΔG° value was −35.02 kJ.mol−1. The quality of pomelo peel essential oil obtained by steam distillation was characterized by its high limonene content (96.996%), determined by GC-MS.

“…The kinetics of water and steam distillation of essential oils from some plant materials have been observed to deviate from the above-mentioned exponential kinetic models. An almost linear increase during the initial period of the water distillation of parsley seeds was noticed [23], while a sigmoid variation of the essential oil yield with time was observed for various plant materials exposed to either water or steam distillation, such as the aerial parts of Artemisia judaica [35], the flowers, leaves and stems of common sage [8], lavender flowers and leaves [34], as well as rosemary leaves and caulis [36]. In these cases, the variation of the essential oil yield from its lowest, A 1 , to the highest, A 2 , asymptotic value can be described by a Boltzmann sigmoid curve:…”

The present work deals with the modeling of the kinetics of essential oils extraction from plant materials by water and steam distillation. The experimental data were obtained by studying the hydrodistillation kinetics of essential oil from juniper berries. The literature data on the kinetics of essential oils hydrodistillation from different plant materials were also included into the modeling. A physical model based on simultaneous washing and diffusion of essential oil from plant materials were developed to describe the kinetics of essential oils hydrodistillation, and two other simpler models were derived from this physical model assuming either instantaneous washing followed by diffusion or diffusion with no washing (i.e., first-order kinetics). The main goal was to compare these models and suggest the optimum ones for water and steam distillation and for different plant materials. All three models described well the experimental kinetic data on water distillation irrespective of the type of distillation equipment and its scale, the type of plant materials and the operational conditions. The most applicable model is the one involving simultaneous washing and diffusion of the essential oil. However, this model was generally inapplicable for steam distillation of essential oils, except for juniper berries. For this hydrodistillation technique, the pseudo first-order model was shown to be the best one. In a few cases, a variation of the essential oil yield with time was observed to be sigmoidal and was modeled by the Boltzmann sigmoid function.

“…The steam distillation of two fifty grams of waste sweet lime peels (feed material) was carried in a round bottom flask of the clevenger apparatus. Instead of adding water, vapour produced by the steam generator was injected to the clevenger apparatus by means of steam injector [9]. The oil layer obtained is recovered from water by adding solvent (petroleum ether) which has low boiling point.…”

This research work was designed to extract essential oil from sweet lime peel (solid waste). The feed material selected for study is sweet lime peel. The disposal of waste product such as peels often has a legal restriction problem and treatment process involved requires higher costs. Transformation of this waste in to useful products could cut global treatment costs. Hence the objective of our experimental work was to convert sweet lime peel in to essential oil which is in huge demand in food, pharma and cosmetic industry. In our experimental work eextraction of essential oil was evaluated and comparison study was made between steam distillation, hydro-distillation, solvent extraction and hydro-steam distillation. Maximum extraction yield of 2.4 % was achieved at 90 min of contact by hydro-distillation. Hydro-distillation method offers advantages in comparison with other three methods in terms of energy saving, cleanliness and reduced waste water. Chemical constituents of essential oil samples were evaluated in terms of qualitative and quantitative analyses by gas chromatography/mass spectrometry and physical techniques. The chemical profile includes thirty two components which were identified in the extracts by Gas chromatography-Mass spectroscopy (GC-MS) analysis. The dominant component identified was limonene (65 .2 to 72.8%).
