High oil recovery and meal production are the driving force of oil extraction process. • Ethanol is economically feasible as soybean oil solvent. The extraction rates of the solvents increased in the following order: isopentane, pentane, isohexane, and hexane. All processes were implemented and simulated in EMSO, Environment for Modeling, Simulation and Optimization, which is an equation-oriented process simulator. Hexane extraction is a soybean cost leading process. We use cookies to help provide and enhance our service and tailor content and ads. If you do not receive an email within 10 minutes, your email address may not be registered, The oil was almost retained within the second cell wall. The extraction rates of the solvents increased in the following order: isopentane, pentane, isohexane, and hexane. A bibliography on the solvent extraction of soybeans and soybean products 1944–1968. For ethanol, four different methods of solvent recovery were evaluated. During the transition to a low carbon economy, techno-economic-environmental analyses of industrial processes will have increasing relevance. Techno-economic analysis is performed to evaluate the economic feasibility of soybean oil production by hexane extraction based on historical scenarios from 1980 to 2015. However, soybean meal is the main driving force for soybean oil production due to its significant amount of productivity and revenues. Hexane extraction is the most common method used in the industry to produce soybean oil due to its high oil recovery and lower production cost.

Hexane in Solvent extraction method. per year in an industry that crushes 125 ton per hour of soybean. https://doi.org/10.1016/j.jclepro.2019.118660. In the hexane extraction process, material costs, especially for soybean prices, have the most significant effect on profit. Extraction of simmondsins from defatted jojoba meal using aqueous ethanol. To improve AEP oil yields, experiments were conducted to probe the mechanisms of oil release. Learn about our remote access options, Iowa Engineering Experiment Station, Iowa State University of Science and Technology, Ames, Iowa. © 2017 Elsevier B.V. All rights reserved. Soybean flakes were extracted in glass extraction apparatus with four hydrocarbon solvents: hexane, isohexane, pentane, and isopentane. Aqueous extraction processing (AEP) of soy is a promising green alternative to hexane extraction processing. Hexane extraction is the most common method used in the industry to produce soybean oil due to its high oil recovery and lower production cost.
An economic analysis and a Life Cycle Assessment of the processes were performed. Additionally, sensitivity analysis is also applied to examine which factor affects profit the most.

Ethanol carbon footprint is lower than hexane's for soybean oil extraction. Quality and fatty acid composition of the oils extracted by the four solvents showed no significant differences. To begin the process of solvent extraction, oil seeds (soybean, rapeseed etc.) Learn more. Capital investment, operating costs, revenues, and profits are main parameters to consider when estimating profits, gross margin, return on investment (ROI), and payback time and are the indices used to evaluate the profitability of the process.
The amount of extracted oil was determined at 10 min intervals for 60 min. Replacing hexane by ethanol might avoid emissions of 10.6 × 103 ton of CO2eq per year. Hexane in its pure form is a colorless liquid , and its boiling point is between 50℃ – 70℃ all of which work in favor for oil extraction. Ambient n-hexane extraction was also possible; however, residual oil remained in the oil bodies. Please check your email for instructions on resetting your password. Techno-economic-environmental analysis of soybean oil extraction with ethanol. With the demands of soybean oil increasing either in food or industrial applications, expansion plans are considered by many companies to increase production capacity. Flotation of oil drops by centrifugation was easily done. The amount of extracted oil was determined at 10 min intervals for 60 min. By continuing you agree to the use of cookies. Soybean flakes were extracted in glass extraction apparatus with four hydrocarbon solvents: hexane, isohexane, pentane, and isopentane. https://doi.org/10.1016/j.indcrop.2017.07.036. The results showed that all scenarios were economically feasible, with positive NPV, but hexane presented an approximately 10.2% higher NPV then the best-case ethanol process (hydrous). Copyright © 2020 Elsevier B.V. or its licensors or contributors. Within this context, the replacement of hexane by ethanol (either hydrous or anhydrous) as solvent for soybean oil extraction is assessed. are removed of impurities and dried to reduce moisture content.
