The solvent is then percolated through perforated plate; crude soybean oil is obtained after the hexane is removed from the miscella. Flakes thickness from 0.02 to 0.06mm decreases the
ducted with soybean akes using the selected solvents, and their performance was compared with the universal solvent hexane used in the vegetable oil industry for a meaningful assessment.

Separation of soybean oil/n-hexane and soybean oil/n
Similar behavior was observed in the separation of mixtures of soybean oil and n-hexane. For the same conditions of pressure and O:S, the total permeate fluxes were
These SRNF can be a potential option to be used in the solvent recovery and oil concentration from soybean oil/n-hexane micelles at industrial scale. Membrane plants utilizing

The membrane separation process has proven to be a promising alternative to solvent recovery in soybean oil extraction. Key words: Soybean oil, n-hexane, ultrafiltration, nanofiltration, polymeric
Separation of soybean oil/n-hexane and soybean oil/n
In the system using n-hexane as solvent, soybean oil rejections varied between 8.0 and 40% (5 Solvent recovery from soybean oil/hexane miscella by polymeric membranes.
This work reports the use of ceramic membranes with different cut-offs (5, 10 and 20 kDa) for the separation of synthetic mixtures simulating soybean oil industrial miscellas in organic
- What are the independent variables of solvent recovery from soybean oil/hexane miscella?
- According to the study, temperature and pressure were chosen as the independent variables for the solvent recovery process from the soybean oil/hexane miscella (25/75%, w/w).
- Can PDMS/PVDF membranes be used to recover hexane from soybean oil?
- The surface and section of PDMS/PVDF composite membranes were investigated by scanning electron microscope (SEM). The PDMS NF (nanofiltration) membranes were then applied in the recovery of hexane from soybean oil/hexane miscellas (1:3, mass ratio).
- Can hexane be recovered from miscella by membrane separation?
- Several papers reported recovery of hexane from miscella by membrane separation. In their research UF (untrafiltration), NF (nanofiltration) and RO (reverse osmosis) membrane are tested [4 8], but the results are not satisfactory.
- Can n-propyl alcohol be used to separate refined soybean oil/n-hexane mixtures?
- In this work, the separation of refined soybean oil/n-hexane mixtures was investigated using a commercial hollow fiber ultrafiltration membrane 50 kDa. Three alcohols with different chain lengths were tested for the conditioning of the membrane; n-propyl alcohol showed the highest n-hexane permeate flux after conditioning.
- What is the evaporation process of oil & hexane?
- The sol- vent content of the miscella (mixture of extracted oil and solvent) in the extractor exit is always 70% to 75% (by mass). The miscella is then evaporated to separate the oil and hexane. Since the process involves solvent phase change, the evaporation process requires considerable amount of energy (about 530kJ per kg of hexane) .
- What is the effect of SEPA GH on oil/hexane miscela flux?
- SEPA GH has shown a higher oil/hexane miscela flux and a greater retention of oil (67.1%), which occurs under conditions of relatively low pressure (15 bar) and high temperature (45 °C). The permeate resulting from this process has a final oil content of 8.0%, but a low permeate flux (8.2 L m −2 h −1 ).
