Supercritical extraction of sunflower oil: A central
Supercritical carbon dioxide (SC-CO 2) extraction of sunflower seed for the production of vegetable oil is investigated and compared to conventional methods.The effects of extracting variables, namely pressure, temperatures, particle size, SC-CO 2 flow rate and co-solvent, on SC-CO 2 extraction are investigated. The maximum yield for sunflower oil is found to be about 54.37 wt%, and is
Extraction of sunflower oil from sunflower seeds (Heliantus annuus L.) using supercritical CO 2 was studied.The shrinking core model was applied to the modeling of the packed-bed extraction process. The experimental data were obtained for extraction conducted at the pressures of 20, 30, 40, 50 and 60 MPa; the temperatures of 313, 333 and 353 K, the CO 2 flow rates of 1–4, and 6 cm 3 CO 2 min
Supercritical fluid extraction of sunflower seed oil
Abstract. The effect of ethanol addition to supercritical carbon dioxide (SC-CO 2), up to 20%, on sunflower seed oil extraction over the range of 150 to 350 bars and 42 to 80°C was studied.A nonrecirculating-made bench-scale system was used as extraction equipment.

Supercritical fluid extraction
Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent.Extraction is usually from a solid matrix, but can also be from liquids.SFE can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product (e.g
The objective of this work was to study the economical viability of supercritical fluid extraction (SFE) of oil and carotenoids from three Amazonian palm trees: buriti, pupunha and pressed palm
Supercritical extraction of sunflower seed oil
Fiori observed a signifi- cant increase in the extraction yield of sunflower seed oil by using supercritical fluid CO 2 when the diameter was reduced from 0.48 to 0.31 mm. Shuit et al. [30
Kenneth J. James, Ph.D., Supercritical Fluid Technologies, Inc. Supercritical Fluid Technologies has announced the introduction of a new version of their SFT-NPX-10 pilot-scale natural products CO2 extractor optimized for the production of pharmaceutical-grade cannabis oil. The new NPX-10 is designed to simplify extraction by utilizing safe
Mathematical Modeling of Sunflower Seed Extraction
Extraction of oil from crushed sunflower seeds with supercritical CO2 was performed at 280 bar and 40 °C on a laboratory apparatus of 0.15 × 10-3 m3 volume and on a pilot plant of 1.5 × 10-3 m3 volume. CO2 flow rate ranged between 5 and 45 kg h-1. To study the influence of the vegetable matrix on the extraction rate, a re-extraction experiment on the extraction product was also performed on
