In the process of solvent extraction, the solvent is recovered through evaporation.1

After the oil has been extracted from the seed meal, the system produces two primary components: the oil-solvent solution, known as the miscella, and the extracted meal, or marc. To recover the solvent, it is removed from both the miscella and the marc through evaporation. Once evaporated, the solvent is collected, allowing it to be reused in the extraction process.21
