Replacing hexane by ethanol for soybean oil extraction
Jan 20, 2024· 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.

Replacing hexane by ethanol for soybean oil extrac BV
Within this context, the replacement of hexane by ethanol (either hydrous or anhydrous) as solvent for soybean oil extraction is assessed. Sugarcane bagasse was the fuel for cogeneration of energy. All processes were implemented and simulated in EMSO, Environment for Modeling, Simulation and Optimization, which is an equation-oriented process

hexane extraction of soybean oil TZÜK
For ethanol, four different methods of solvent recovery were evaluated. • Ethanol is economically feasible as soybean oil solvent. However, the replacement of hexane by ethanol resulted in lower GWP, avoiding the emission of approximately 10,600 ton of CO2eq. Techno-economic-environmental analysis of soybean oil extraction with ethanol.
The aim of this work was to evaluate the feasibility of replacing hexane by ethanol in the soybean oil extraction process. The use of ethanol has very attractive advantages such as: low toxicity, good operational security, as well as being obtained from a biorenewable source.
Life Cycle Assessment of the Replacement of the Hexane by
Brazil is the second larger soybean producer which oil is traditionally extracted with hexane. The replacement of the hexane by ethanol, that comes from a renewable source, has been considered
the substitution of hexane by ethanol (Rittner, 1992). The main goal of this work was to evaluate the ethanol performance on the extraction process of soybean oil. 2. Materials and Methods 2.1 Materials The solvents used in this work were absolute ethanol, from Merck (Germany), with
Comparison between ethanol and hexane for oil extraction
Comparison between ethanol and hexane for oil extrac tion from Quercus suber L. fruits. The aim of this study was to (i) evaluate the feasibility of replacing n -hexane with ethanol for the extraction of oil from Quercus suber fruits and (ii) optimize, at lab scale, sample preparation and extraction time for both solvents used ( n -hexane
At 25 °C, DBU/ ethanol extracted oil more slowly than ethanol or DBU alone, and much more slowly than the hexane control (at 60 °C). Only 45% of the oil was recovered after 60 min using the DBU/ ethanol solution. In fact, the addition of DBU to anhydrous ethanol reduces ethanol's extracting power by nearly half. Increasing the extraction temperature to 70 °C gave marked improvement of 20%
