Resumo

This study evaluated ethyl esters as cosolvent of ethanol in the oil extraction from soybean collets containing two different levels of moisture (3 and 7 mass% of water). Extraction assays were performed in a fixed-bed column, at 60 and 70 degrees C, with a solid:solvent mass ratio of 1:1.5. The composition of the ethyl esters-ethanol mixture was chosen based on densities and dynamic viscosities, and Hansen solubility parameters. Using collets with 3 mass% of water and the rising temperature favored the soybean oil extraction yield. Adding 5 mass% of ethyl esters to ethanol enabled the achievement of a gain of 33% in the oil extraction yield considering collets with 7 mass% of water at 60 degrees C. The use of ethyl esters-ethanol mixture to extract soybean oil is promising, particularly when it is not possible or desirable to subject soybean collets to an additional drying process. (AU)
