Chemical alcohol / water short path molecular distillation machine for oil recycling

Chemical alcohol / water short path distillation machine YMD-150

YHCHEM short path distillation machine, it is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids. This process is characterized by short term exposure of the distillate liquid to high temperatures, by high vacuum pressure (around 1024 mmHg) in the distillation column and a small distance between the molecular distillation and the condenser around 2 cm, where fluids are in the free molecular flow regime, i.e. the mean free path of molecules is comparable to the size of the equipment. This process has the advantages of avoiding the problem of toxicity that occurs in techniques that use solvents as the separating agent, and also of minimizing losses due to thermal decomposition.

short path distillation process description

Feed liquid is admitted into still under high vacuum, immediately spread into a very thin film and forced quickly down the evaporation surface. Heated walls and high vacuum drive the more volatile components (distillate) to the external condenser as the less volatile components (residue) continue down the cylinder. The resulting fractions, thus separated, exit through individual discharge outlets. Depending on application, the desired product is either the distillate or the residue fraction. Small amounts of condensable low MW compounds collect in cold trap upstream of vacuum system. For high solvent loads, an optional external condenser may be installed immediately downstream of the still.
