YHCHEM is also known as a solution provider for global cus-tomers in the areas of distillation, evaporation ...

Jan 01, 2018 The optimization of the process of eucalyptus essential oil refining by molecular distillation was studied. The distillation temperature and distillation pressure had significant influence on the effect of 1,8-cineole and α -pinene fractionation, and the experimental results were optimized by the optimization method of multi response values.

Molecular distillation is a liquid-liquid separation technology. It is different from traditional distillation which relies on the separation principle of boiling point difference, but relies on the difference of the mean free path of different substances to achieve separation.

Molecular distillation is a special liquid-liquid separation technology that operates under extremely high vacuum. It achieves the purpose of separation according to the physical characteristics of different molecular motions of different substances with different mean free paths. The liquid will be separated below the boiling point.

Molecular distillation is a special liquid-liquid separation technology, which is different from the traditional distillation by boiling point difference separation principle, but by different substances molecular movement of the average free path difference to achieve separation. Molecular distillation is considered as the safest mode of ...

Molecular distillation is a technology made exclusively for liquid-liquid separation. While traditional distillation does so with the boiling point difference separation principle, this method separates substances at the molecular level. This allows for a safer and purer technique of distillation. This method also produces a shorter residence ...

Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser.

Molecular Distillation Technology and Applications 2019-12-25 16:39:37 Molecular distillation is a process of distilling and purifying heat-sensitive substances or high-boiling-point substances by utilizing the differences in the free paths of the molecules of …

Molecular distillation technology is the bottleneck of high-purity materials technology,which has been paid widespread attention in many countries.This paper introduces the developments of the molecular distillation technology at home and abroad,as well as the basic principle and application characteristics.Combining the requirements of practical applications,the …

Molecular Distillation Technology. Molecular distillation is a special kind of liquid-liquid separation technology operated in high vacuum (0.1~10Pa) and it’s also called short-path distillation.. Characteristics. It has the characteristics of low distillation temperature , high vacuum , short heating time for material , high degree of separation, etc.

Molecular distillation was studied for the separation of tocopherols from soya sludge, both experimentally and by simulation, under different operating conditions, with good agreement. Evaporator temperatures varied from 100C to 160C and feed flow rates ranged from 0.1 to 0.8 kg/h. The process pressure was maintained at 10 −6 bar, the ...

Oct 22, 2021 Molecular distillation technology is widely used in the food industry, mainly for the separation of mixed oils. W (monoglycerides of fatty acids) can be obtained; 90% high-purity products. After evaporating the monoglyceride molecules from the surface of the distillate, they are immediately cooled to achieve separation. ...

Oct 26, 2021 Molecular distillation technology is an effective method to purify essential oils. It can concentrate a certain main component in aromatic oils, remove odors and colored impurities, and improve its purity. Because this process is carried out under high vacuum and low temperature, the heating time of the material is extremely short, so the ...

Sep 03, 2015 It is special liquid-liquid separation technology, which is quite different from fractional distillation. In molecular distillation we make use of the difference of molecular mean free path of different substances. ... Often molecular distillation is repeated 2 or 3 times and the resultant vacuum oil is called Double Molecular Distilled Vacuum ...

The main operations of molecular distillation are deodorization, decolourisation, decontamination of undesirable substances (pesticides, molecular contaminants), as well as fractionation and concentration of high added value active ingredients for the cosmetic, pharmaceutical and nutraceutical sectors. The chemical and food speciality ...

The Pope Wiped-Film Still consists of a heated body into which a fluid system requiring some degree of separation is continuously fed. The fluid is spread into a thin film by a rotating wiper blade assembly driven at a predetermined speed. The film, while being forced into turbulent flow by the wiper blades, progresses down the inside body wall ...

The yield and the influence on product viscosity of molecular distillation separation heavy resid under different technology conditions were studied and the results showed that the technology conditions of molecular distillation separation heavy resid is residual pressure 10 pa, temperature 250 oC, blown film machine speed 230 r/min. the ...
