Simulation of vegetable oil extraction in counter-current crossed flows using the artificial neural network

Solvent extraction modeling of vegetable oil and its minor compounds

“…Moreover, it assumes an equilibrium state between pore and solid phases at any point of the field, including the loading zone. Thomas et al (2005) developed a model for soybean oil solvent extraction in a ''Rotocell'' extractor. The model considers a two-dimensional approach to countercurrent cross flows with oil diffusion for miscella, the effect of the existing processes at the drainage and loading sections, oil losses, and the variation in miscella viscosity and density.…”

Phenomenological model for the prediction of Moringa oleifera extracted oil using a laboratory Soxhlet apparatus

“…For that reason, it is difficult to explain all phenomena which take place during the solvent extraction through a single theory (Carrin and Craspite, 2008). Different authors have considered the mathematic modeling of vegetable oil extraction (Thomas et al, 2005).…”

Modelagem Matemática dos Processos de Transferência de Massa em Extrator “Crown-Model”

“…Mas ele nãoé sensível a fatores importantes tais como: parâmetros geométricos do extrator, características da matéria prima e parâmetros do regime operacional. Dessa forma, estão sendo elaborados modelos matemáticos, apoiados em leis e regularidades peculiares dos processos físicoquímicos em meios porosos [3,8,9]. Nos trabalhos [8,9] foram apresentados os modelos matemáticos dos extratores "Rotocell" e "De-Smet" onde nos Fluxos-CCC da matéria prima e da miscela foram considerados os principais fenômenos: transferência doóleo entre as fases, difusão pelo campo de extração e existência de zonas de carregamento de 2 drenagem e de bandejas.…”
