Solvent extraction of vegetable oils: Numerical

Highlights A process for the extraction of vegetable oils from soybean seeds was developed. The extraction with a solvent was carried out in a fixed-bed extractor. A transient model to simulate the behavior of fixed-bed extractor was presented. The governing equations were numerically solved using the finite volume method. The model predicted, with good agreement, the behavior of the
