Modeling of Supercritical CO2 Extraction of Palm Oil and Tocopherols Based on Volumetric Axial Dispersion

Regular Solution Approach to Modeling the Supercritical Fluid Extraction of Two-Component Solutes from Ground Oilseeds

“…Once the so-called free oil is exhausted, , the concentration of the surrounding bulk solution becomes relatively low, and only the extraction of oil from large particles takes place. Outlet solute concentrations are 1–2 orders of magnitude smaller than the saturation concentration, and the bulk solution concentration becomes vanishingly small to affect the particle-scale extraction rates.…”

“…Once the so-called free oil is exhausted, 44,45 the particle-scale extraction rates. To simplify further analysis and to ensure the numerical accuracy of the model equation solution, we consider vanishingly small solute concentrations on the macro-scale level of the packed bed,…”

Analytical and hybrid-neuro-differential approaches for describing contaminant removal from aqueous systems

“…SLI models have been used in detailed numerical solutions of solid-gas adsorption (Thorpe, 2022) and extraction operations (Castillo-Santos et al, 2010;Promraksa et al, 2020). In addition, they have been also proven useful for obtaining analytical solutions describing the simultaneous heat and mass transfer between a moist solid and air during convective drying (Vargas-González et al, 2021).…”

Determination of free fatty acids in crude vegetable oil samples obtained by high-pressure processes

“…Recently, studies based on extraction using supercritical CO 2 have been directed towards some unconventional vegetable oils, such as wheat germ ( Bojanić et al, 2019 ), palm ( Promraksa et al, 2020 ), and “bacaba-de-leque” – a Brazilian palm tree ( Cunha et al, 2019 ). Benito-Román et al (2018) evaluated the quinoa oil extraction using CO 2 , proving that the oil obtained by scCO 2 presented higher antioxidant capacity and tocopherol content than the oil extracted with hexane, and also that the extraction rate may be strongly controlled by the pressure rate (20–40 MPa).…”
