“…Transmembrane pressure played a vital role in affecting the essential oil retention when using these membranes. In a similar study by Carlson et al (2005), RO membranes were used in separation and recovery of carbon dioxide from limonene after extraction with SC-CO 2 at 12 MPa and 40 • C. The RO membranes were aided in the recovery of approximately 70% of the carbon dioxide from the essential oils mixtures. Such studies involving coupling of SC-CO 2 extraction processes with nanofiltration membranes have shown advantages of good performance at high permeate fluxes mainly due to the low viscosity of SC-CO 2 .…”

“…Carlson et al 10 avaliaram três membranas de osmose reversa (SG, AK e CE -Osmonics) e uma de nanofiltração (HL -Osmonics) quanto à retenção de D-limoneno sob extração por CO 2 SC. Os experimentos foram conduzidos sob pressão de 12 MPa, pressão transmembrana de 0,5 MPa e temperatura de 40 °C.…”

“…As aplicações geralmente melhoram o processo de produção, simplificando-o, reduzindo o consumo de energia e a produção de águas residuais, com a possibilidade de não adição de insumos químicos e de fácil mudança de escala 5 . A maioria das pesquisas utilizando membranas em tecnologia de lipídios tem focado a recuperação de solvente da miscela de extração, a degomagem, o branqueamento, a neutralização, a hidrólise de óleos e gorduras, a síntese enzimática, a extração e a purificação de matrizes lipídicas através da utilização de reatores de membranas e fluidos supercríticos [6][7][8][9][10] .…”

“…6,7 Some studies were performed using reverse osmosis membranes for separation of supercritical fluid and analytes. [8][9][10] In the case of solid-phase trap, the sample is reconstituted with a rinse solvent which, containing sample fractions, is washed to the output vials. All methods of analytes collection after supercritical fluid extraction have major or minor drawbacks (e.g.…”
