The oil / solvent mixture that exits the extractor is known in the industry as miscella and has a solvent content of between 70 and 80% by weight. The objective of distillation is to thermally separate the miscella, into a fraction of liquid oil and a fraction of solvent vapor, and recover the solvent to be reused. This is what distillation is about and in this presentation we will make a brief description of the different processes that take place. We will also make a description of the most relevant equipment. At the same time, the most recent developments in this area will be specially noted.
