Short Path Distillation Unit Technoforce

A Short Path Distillation Unit (SPDU) is also called as Molecular Distillation Unit. It is distinguished from a standard Agitated Thin Film Evaporator by an internally mounted condenser. The vapor generated on the heated surface travels a very short distance to reach the condenser surface, thus eliminating pressure drop.

Alkane Molecular Short Path Rotating Edge Distillation

Alkane Molecular Short Path Rotating Edge Distillation Alkanes - Rutgers University Alkanes are non-polar, and are said to be hydrophobic (‘water hating’) since they do not dissolve in water. Typically the density of alkanes is around 0.7g/ml, and so when an alkane and water are mixed, they will form two separate phases, with the alkane on top.

Bleached olive pomace oil (BOPO) was distilled using a short-path molecular distillation unit to determine the impacts of distillation conditions on the removal of 15 PAHs from the list of 16 EPA-priority pollutant PAHs. The removal of PAHs was achieved at elevated temperatures (110–230C) and pressures (0.05, 0.5, 5 mbar).

Jun 27, 2013 So the pretreatment of oil is very important. The investment for short path process is higher than vessel type. Also the molecular evaporated oil has darker color, so the after treatment takes more works. The advantage is the oil from short path treatment maintains more than 70% additives of oil, so the oil indexes are higher.

Distillation Process And Influencing Factors In Short Path ...

May 10, 2020 The short path distillation plant consists mainly of a cylinder, an inner condenser and a rotor. The inner condenser is in the center of the evaporator, and the rotor with membrane scraping system rotates between the evaporator and condenser. The distillation process is: the material is added from the top of the evaporator, and is continuously ...

Application of Molecular Distillation - Lab Instrument ...

Molecular distillation is a distillation process done under high vacuum. The very short distance the vapor travels before condensing ensures minimal to no loss due to surface hold-up of the vapor and is an immediate release from vapor to condenser surface. This distillation process is classified as short path distillation and is also referred ...
