For a typical distillation process, oil plants are initially crushed to release the oils, and they are then steam distilled. During this process, the essential oils vaporize and rise up with the steam. The oil vapors are captured and are allowed to condense back into biooil liquids (Champagne, 2008). To achieve a better distillation, high-tech technologies can be used, e.g., vacuum distillation (Rahman et al., 2018) and molecular distillation (Mezza et al., 2018).

Several studies conducted over the years have highlighted molecular distillation, supercritical extraction, solvent extraction, and crystallization techniques as efficient methods of phytonutrient recovery, with purity suitable for applications in cosmetics, pharmaceuticals, and food (Dumont and Narine 2007). Among these techniques, molecular distillation exhibits advantages in separating, purifying, and concentrating natural products over others that use solvents, avoiding environmental and toxicity problems (Jiang et al. 2006).

Several authors have shown molecular distillation as a potential approach for the separation of bio-oil (Guo et al. 2010; Wang 2013; Wang et al. 2009). Molecular distillation operates at short heating time, low temperature, and presents high separation efficiency (Wang 2013).
