“…Furthermore, the BICM gave comprehensive knowledge of the mass transfer mechanism of the extraction process, including the mass transfer coefficients and the extraction periods governed by convection and diffusion. For further optimization and scale‐up design, simulation and optimization tools such as simulator Aspen HYSYS™ can be used based on the extraction profile evaluated from experimental studies for evaluating techno‐economic model of the process …”

Patchouli oil is a high‐value essential oil used in cosmetic, food, and pharmaceutical industries. In this work, supercritical fluid extraction of patchouli oil with various operating process parameters (pressure, temperature, flow rate, and particle size) were studied and the results were modeled using the broken and intact cell model (BICM). From the experimental studies, it was found that the extraction rate was improved at higher pressures and flow rates, where the mass transfer resistances in the liquid and solid phase were decreased; however, the increase in temperature had an inverse effect on extraction rate and mass transfer. In the case of particle size, a moderate size of 0.3 to 0.6 mm gave the optimal extraction rate. The BICM predictions showed good agreements with experimental data and gave valuable insights regarding the mass transfer mechanism of the extraction process, including mass transfer coefficients and extraction periods governed by convection and diffusion.

“…Multistage gas extraction in countercurrent columns has been considered to be an alternative separation technique for the extraction and fractionation of liquid mixtures with potential applications in the food industry [ 35 , 36 , 37 ]. The applications include the removal of terpenes from citrus oils [ 38 , 39 ], the isolation of polycyclic aromatic hydrocarbon (PAH) oligomers [ 40 ], the deacidification of olive and rice bran oils [ 41 , 42 ], the fractionation of fatty acids from palm fatty acid distillates [ 43 , 44 ], the purification of fat-soluble substances (tocopherols, sterols, carotenes, and squalene) from palm oil, olive oil, soya deodorize distillates, olive oil deodorize distillates, and hexane extracts of olive leaves [ 41 , 45 ], the separation of aroma constituents from aqueous solutions of apple, brandy, and wine-must aroma [ 46 ], and the fractionation of the model mixture of squalene/methyl oleate [ 47 , 48 ], among other applications [ 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ].…”

“…Despite the wide range of applications of multistage gas extraction in countercurrent packed columns, particularly in the food industry, as reported in the reviews by Brunner and Bejarano et al [ 36 , 49 ], only a small number of works are devoted to the simulation of multistage gas extraction using self-made computer codes or commercial chemical process simulators, such as Aspen-HYSYS, as described chronologically in what follows [ 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ].…”

“…Moraes et al [ 55 ] simulated the recovery of provitamin A from esterified palm oil using a mixture of SC-CO 2 /ethanol as a solvent with the commercial simulator HYSYSTM, adapting the process units to the typical operating conditions of SFE. Because esterified palm oil is a complex mixture, it was necessary to insert the compounds as hypotheticals to predict/estimate the physical and thermo-physical properties using the UNIFAC group contribution.…”

In this work, the deoxygenation of organic liquid products (OLP) obtained through the thermal catalytic cracking of palm oil at 450 °C, 1.0 atmosphere, with 10% (wt.) Na2CO3 as a catalyst, in multistage countercurrent absorber columns using supercritical carbon dioxide (SC-CO2) as a solvent, with an Aspen-HYSYS process simulator, was systematically investigated. In a previous study, the thermodynamic data basis and EOS modeling necessary to simulate the deoxygenation of OLP was presented. This work addresses a new flowsheet, consisting of 03 absorber columns, 10 expansions valves, 10 flash drums, 08 heat exchanges, 01 pressure pump, and 02 make-ups of CO2, aiming to improve the deacidification of OLP. The simulation was performed at 333 K, 140 bar, and (S/F) = 17; 350 K, 140 bar, and (S/F) = 38; 333 K, 140 bar, and (S/F) = 25. The simulation shows that 81.49% of OLP could be recovered and that the concentrations of hydrocarbons in the extracts of absorber-01 and absorber-02 were 96.95 and 92.78% (wt.) on a solvent-free basis, while the bottom stream of absorber-03 was enriched in oxygenated compounds with concentrations of up to 32.66% (wt.) on a solvent-free basis, showing that the organic liquid products (OLP) were deacidified and SC-CO2 was able to deacidify the OLP and obtain fractions with lower olefin contents. The best deacidifying condition was obtained at 333 K, 140 bar, and (S/F) = 17.

“…Even though simulation and optimization tools have been widely used for the design of chemical processes, their application has been very limited in vegetable oil processing particularly at supercritical conditions. De Moraes simulated and optimized the supercritical extraction of carotene from esterified palm oil using commercial simulator HYSIS. They found that it was possible to obtain high yields of carotenes via two cycles of supercritical extraction.…”

This work describes the conceptual development of a new process for palm oil refining using supercritical fluid extraction (SFE) technology. The first step was to model the phase equilibrium behavior of a crude palm oil (CPO)-supercritical CO 2 mixture. Next, a new flowsheet structure was synthesized to recover highpurity palm oil and its minor components. The new SFE process was finally simulated using Aspen Plus commercial process simulator version 10.2.1 based on the Redlich-Kwong-Aspen (RKA) thermodynamic model. The results obtained were in good agreement with the pilot plant data reported in the literature. It is envisioned that the development of a new, intensified palm oil refining process that is based on SFE technology can make the refining process drastically simpler and overcome the limitations of the existing technology for palm oil refining.
