Extraction of perfumes and flavours from plant materials with liquid carbon dioxide under liquid—vapor equilibrium conditions

Simulation of Eucalyptus cinerea oil distillation: A study on optimization of 1,8-cineole production

“…However, as mentioned earlier, the waxy thin layer on the foliage surface mainly contributes to the mass transfer resistance. Hence, Langmuir gas adsorption model was considered for the purpose of process simulation, as the same was reported for use in the extraction of some spice crops [28].…”

Supercritical CO2 extraction of nimbin from neem seeds––a modelling study

“…Two different approaches have been proposed for the mathematical modelling of the supercritical fluid extraction (SFE) of natural substance, those are the empirical model, it can be useful when information on the mass transfer mechanisms and on the equilibrium relationships is missing; however, these models are little more than an interpolation of the experimental results (Barton, Hugher, & Hussein, 1992;Kandiah & Spiro, 1990;Naik, Lentz, & Maheshawari, 1989) and differential mass balance model (Goto, Sato, & Hirose, 1993;Goto, Roy, Kodama, & Hirose, 1998;Reverchon, 1996;Reverchon & Poletto, 1996;Roy et al, 1996). To develop a scaleup procedure from laboratory to pilot and industrial scale, we need mathematical models.…”

Mathematical modeling of supercritical fluid extraction of oil from canola and sesame seeds

“…Three different approaches have been proposed for SFE mathematical modeling. The first approach is based on the use of an empirical kinetic equation to describe experimental data (Naik et al, 1989;Ngueyn et al, 1991;Subra et al, 1998;. These empirical relations are useful when there is no information about equilibrium relations and mass transfer mechanisms.…”
