Replacing hexane by ethanol for soybean oil

Highlights. Techno-economic-environmental analysis of soybean oil extraction with ethanol. Ethanol is economically feasible as soybean oil solvent. Ethanol carbon footprint is lower than hexane's for soybean oil extraction. Replacing hexane by ethanol might avoid emissions of 10.6 × 10 3 ton of CO 2eq per year.

1947] EXTRACTION OF SOYBEAN OIL 193 of a two-phai;e mixture of the system trichloroethylene--95 percent ethanol-1mybean oil. From the data presented it is seen that the greatest increase in solubility of soybean oil with temperature rise is secured when abso-. litte ethanol and trichloroethylene are used.

Oilseed Extraction - Crown Iron Works

Increase in solvent cost made solvent conservation a high priority. Crown Iron Works Company is a pioneer in this evolution. Crown, a company with more than 135 years of experience in metal fabrication, entered the solvent extraction area in 1946 with several bold new concepts in truly continuous extraction.

Deacidification of Soybean Oil Combining Solvent ...

The aim of this work was to study the removal of free fatty acids (FFAs) from soybean oil, combining solvent extraction (liquid-liquid) for the separation of FFAs from the oil and membrane technology to recover the solvent through nanofiltration (NF). Degummed soybean oil containing 1.05 ± 0.10% w/w FFAs was deacidified by extraction with ethanol.

Extraction of soybean oil using ethanol and mixtures

The kinetics and thermodynamics of soybean extraction using ethanol and ethanol + alkyl esters mixtures (biodiesel) as co-solvent were investigated. The extraction parameters investigated were temperature (25, 40 and 55°C) and biodiesel to ethanol mass ratio. The extractions were carried out in batch mode at a fixed solvent to soybean mass ratio (4:1).

Soybean oil deacidification by liquid–liquid extraction ...

Soybean oil (SO) was deacidified by liquid–liquid extraction (LLE) in a perforated rotating disc column using ethanol as solvent. The extraction assays were performed using two approaches: in the first, response surface methodology (RSM) was used to evaluate the effect of perforated discs' rotation speed and solvent hydration on the transfer ...

The nondistillation alcohol extraction process for

A new vegetable oil extraction process has been developed, with alcohol as the oil solvent. The process requiresno distillation to recover the oil or the solvent characteristics of the alcohol. This has been demonstrated by reuse of the solvent more than 85 times.
