SHORT PATH MOLECULAR DISITILLATION

Short path molecular distillation (short-path distillation) is a new separation technique that addresses the
problems that conventional distillation techniques can not solve. It can achieve"liquid-liquid" separation
at very low vacuum according to the mean free path difference of molecular motion under the temperature
of much lower than the liquid boiling point. Mainly the use of scraper system forcing liquid film evapora-
tion or distillation of a highly efficient evaporation, distillation equipment, deodorization, degassing reac-
tion and supporting heating, cooling and other unit operations, can be widely used in food, fine chemicals,
electronic materials, plastic engineering and polymer (such as polyols, fatty acids, polyphenols, polyure-
thanes, epoxy resins, milk fat, GMS, flavors and fragrances, heavy oil and paraffin oil) purification and so
on.  The system can also be used to recover organic solvents from industrial effluents. Especially suitable
for high boiling point, heat-sensitive, easily oxidized material separation and purification.
