Distillation Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka, and the fractionation of crude oil into useful products such as gasoline and heating oil.

introduction molecular distillation is a high vacuum process, whereby material distils from an evaporating surface to a relatively cool condensing surface, positioned directly opposite to it, under such an operating pressure that the mean free path of the distilling molecules is greater than the distance between the evaporating and condensing …
Jan 05, 2020 Molecular distillation is prominent with the advantages of low temperature treatment and high vacuum application, which is very suitable for thermolabile compounds and is used for concentrating and refining EOs [34,35]. At present, there are seldom reports on the antibacterial and anticancer activity of Eos obtained by molecular distillation.
Jul 15, 2020 An Old Process. Distillation itself is an old process, one used in many industries, but most notably for making alcohol. Traditional short-path distillation, like that of an old moonshine still, uses a boiling flask to heat the material so it evaporates and is caught on a condenser above. The mash is heated in the flask and the alcohol boils off first.
Jun 23, 2014 It was concluded that first scheme, which involved the removal of TAG in the first distillation stage at 250C, followed by separation of the MAG and free fatty acid (FFA) from distillate at 180C in second distillation step, was able to meet product specifications with more than 80-wt% of DAG purity without exceeding the limit of 0.1-wt% FFA.

Nov 03, 2014 Short path and molecular distillation were developed in the 1930s and 1940s mainly in the UK and in the USA. In short path distillation, the produced vapours do not have contact with the liquid any more. The number of theoretical stages is 1 at a small distillate rate and may rise up to 2.2 at a higher evaporation rate. A first short path ...
