Feed temperature influence on the efficiency of a molecular evaporator

Simulation of Molecular Distillation Process for Lactic Acid

“…In centrifugal distiller, the centrifugal force allows for the formation of a thin liquid film that passes through the heated disk and makes contact with the condenser surface [12]. Falling film distiller uses gravity force to promote a thin film on the evaporating cylinder, usually with a wiping element that mixes and distributes the liquid over the whole evaporator surface [13].…”

“…The operation temperature was the analyzed parameter, since it is the limiting factor for the great majority of MD applications [13]. The flash temperature was varied in order to evaluate in which operation temperature a residue mass percentage was equal to the obtained using a real molecular distillation process.…”

Potential Applications of Green Technologies in Olive Oil Industry

“…Molecular distillation is characterized by a short time exposure of the distilled liquid to elevated temperature and high vacuum, with a small distance between the evaporator and the condenser (Lutišan et al, 2002). The small distance between the evaporator and the condenser and a high vacuum in the distillation gap results in a specific mass transfer mechanism with evaporation outputs as high as 20-40 gm −2 s −1 (Cvengroš et al, 2000). Due to short residence time and low temperature, distillation of heat-sensitive materials is accomplished without thermal decomposition.…”

Extraction and Enzymatic Modification of Functional Lipids from Soybean Oil Deodorizer Distillate

“…Furthermore, this process has advantages over other techniques that use toxic or flammable solvents as the separating agent, avoiding toxicity and environmental problems. The combination of a small distance between the evaporator and the condenser of only a few centimetres and a high vacuum in the distillation gap, results in a specific mass transfer mechanism with evaporation outputs as high as 20-40 gm−2 s−1 (Cvengros et al, 2000). Under these conditions (e.g., short residence time and low temperature), distillation of heatsensitive materials is accomplished without or only negligible thermal decomposition.…”
