“…Researchers from this group observed that when performing continuous fractionation, the selectivity was not significantly influenced by the use of an external reflux (reflux mode). On the other hand, they found that the solvent-to-feed ratio, and feed-inlet position were important variables in the fractionation of citrus fruit essential oils [63][64][65]67,68,71,73]. In fact, better results were obtained operating the column in the stripping mode [66].…”

“…Multistage gas extraction in countercurrent columns has been considered as an alternative separation technique for the extraction and fractionation of liquid mixtures with potential applications in the food industry [60][61][62]. The applications include removal of terpenes from citrus oils [63][64][65][66][67][68][69][70][71][72], separation of fatty acids ethyl esters from butteroil, fish oil, and model mixtures [73][74][75], isolating of polycyclic aromatic hydrocarbon (PAH) oligomers [76], Isolation of antioxidant compounds from orange juice [77][78], deacidification of olive and rice bran oils [79][80][81][82], fractionation of fatty acids from palm fatty acid distillates [83][84], purification of fat-soluble substances (tocopherols, sterols, carotenes, and squalene) from palm oil, olive oil, soya deodorize distillates, olive oil deodorize distillates, and hexane extract of olive leaves [81,[85][86][87][88][89][90], fractionation of alcoholic beverages to obtain distillates with lower alcoholic content [91][92], separation of ethanol from aqueous solutions [93], separation of aroma constituents from aqueous solutions of apple, brandy, and wine-must aroma [94][95][96], fractionation of non-esterified alkoxyglycerols from shark liver oil…”

In this work, the deoxygenation of organic liquid products (OLP) obtained by thermal catalytic cracking of palm oil at 450 °C, 1.0 atmosphere, with 10% (wt.) Na2CO3 as catalyst, in multistage countercurrent absorber columns using supercritical carbon dioxide (SC-CO2) as solvent, with 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 has been presented [Molecules 2021, 26, 4382. https://doi.org/10.3390/molecules26144382]. This work address a new flowsheet, consisting of 03 absorber columns, 10 expansions valves, 10 flash drums, 08 heat exchanges, 01 pressure pump, and 02 make-up 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 the concentrations of hydrocarbons in the extracts of absorber-01 and absorber-02 were 96.95 and 92.78% (wt.) in solvent-free basis, while the bottom stream of absorber-03 was enriched in oxygenates compounds with concentrations up to 32.66% (wt.) in solvent-free basis, showing that organic liquid products (OLP) was deacidified and SC-CO2 was able to deacidify OLP and to obtain fractions with lower olefins content. The best deacidifying conditions was obtained at 333 K, 140 bar, and (S/F) = 17.

In order to keep subscribers up‐to‐date with the latest developments in their field, John Wiley & Sons are providing a current awareness service in each issue of the journal. The bibliography contains newly published material in the field of flavour and fragrance. Each bibliography is divided into 7 sections: 1 Flavour of food; 2 Fragrances; 3 Essential oils; 4 Food constituents; 5 Taints & off‐flavours; 6 Sensory evaluation & psychophysics; 7 Apparatus & methodology. Within each section, articles are listed in alphabetical order with respect to author. If, in the preceding period, no publications are located relevant to any one of these headings, that section will be omitted (12 weeks journals. Search ended 19th. Feb. 2002)
