Green solvents and technologies for oil extraction from
Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a
The three major steps involved in solvent extraction are oilseed cleaning and conditioning, oil extraction, and separation of the miscella. Crude oil and meal quality depend mostly on type of solvent used, reaction temperature, and type of pretreatment given to the oilseed [ 25, 26 ].
Recent advances in green soybean oil extraction: A review
The application of green solvents in soybean oil extraction is reviewed. • Hansen parameters and COSMO-based models can serve as a solvent selection tool. • Direct substitution of hexane with green solvents is the most promising alternative. • Kinetic models and the thermodynamic assessment are analyzed comprehensively. •
It is worthy of note that during oil extraction process, the extraction rate (the rate at which equilibrium is attained) is influenced by factors such as, solute and solvent diffusion capacity, size, shape, internal structure of seeds particles (matrix), and the dissolution rate of the solvent on the oil soluble substances (solute). 21 In other
Extraction and separation of oils: the journey from
In a study, Calophyllum Inophyllum oil seeds are subjected to mechanical oil extraction employing screw press and solvent extraction using n-hexane. It is found that the feed with a moisture content of 15% exhibited the highest yield value of around 51% and 25% in solvent extraction and mechanical extraction respectively.
Although conventional in design and simple to operate, the mechanical technique cannot fully extract oil from the solid oilseed feedstocks (60 – 80% oil extraction efficiency compared to 70 – 99% oil extraction efficiency using solvent extraction), leaving behind residual oil in the cake residue (David and Kopac, 2018, Subroto et al., 2015
Recovery of Base Oil from Used Oil through Solvent
The solvent should have the ability to base oil extraction selectively from used oil and to reject the impurities in the solution so that they can aggregate [ 69 ]. Solvent selection is based on
The main aims of the oilseed preparation include: weakening or breaking the walls of the oil-containing cells, increasing the oil extraction by pressing seeds with a high oil content before solvent extraction and shaping the material to facilitate solvent access to the oil . Typical steps in oilseed processing include scaling, cleaning
A short review of green extraction technologies for rice bran oil
Hexane is the most common solvent used in rice bran oil extraction . This solvent is cheap and efficient, but it is a petroleum-based solvent, volatile, flammable, and dangerous for humans and for the environment . Several efforts have recently been made to find alternatives to this organic compound, focusing on green, non-petroleum-derived
The AVISTA solvent extraction technology (Enhanced Selective Refining, ESR) for vacuum distillates from used oils meets the requirements for a modern re-refining technology with regard to full conservation and recovery of the valuable synthetic and semisynthetic base oil components (PAO, XHVI, HC oils) and quantitative elimination of toxicologically critical components present in the used oils
