31 factors such as extraction temperature and solvent composition (different % of limonene in 32 ethanol) were optimized by means of three-level factorial design using as responses 33 variables the extraction yield and total amount of carotenoids in the extract.

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.

The The 0.8 MPa pressure drop (8 bar or 115 psi) observed at 2500 limonene/methanol/water system had a very small density rpm is very moderate at this high rotor rotation due to the low difference between its two phases precluding its use with limonene − (methanol/water) density difference (Table 2).

The left side of the membrane is in contact with a reservoir of methane held at constant pressure. long-time extraction rates previously identified in field scale data. Moreover, by including.

The effect of extraction temperature flow, pressure, and time were thoroughly evaluated for the extraction of fatty acids, whereas the addition of methanol was also considered in the case of the polyphenols extraction. A quantitative extraction with high efficiency was achieved at a very short time and low temperatures.

In this context, the main objective of this work was to investigate the high-pressure phase equilibrium behavior of binary systems formed by CO2 with the reactant (limonene), the most common solvents (acetonitrile and dichloromethane), and catalysts and the main products (carvone and 1,2-limoneneoxide) of the limonene catalytic oxidation reactions.
