Mar 29, 2000 A method is proposed for the computer-aided molecular design of solvents for extractive distillation. The method is based on a genetic algorithm and uses UNIFAC to estimate relative volatilities. Joback's group contribution methods are used to estimate boiling and freezing points. A number of enhancements, including seeding, evolving fitness functions, and …

Molecular distillation - ScienceDirect

Molecular distillation became an important industry during the past fifteen years, and has enabled many thermally sensitive materials to be prepared on a commercial scale, but the development of stills appears now to have reached a resting-point. After a short introduction, the author discusses in turn the various forms of molecular still existing at the present time, …

Molecular distillation: a powerful technology for obtaining tocopherols ...

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 100 degrees C to 160 degrees C and feed flow rates ranged from 0.1 to 0.8 kg/h. The process pressure was maintained at 10 (-6 ...

Natural compounds obtained through centrifugal molecular distillation

The purpose of this work is to use only molecular distillation in order to recover tocopherols from SODD. Experiments were performed in the range of 140-220 degrees C. The feed flow rate varied from 5 to 15 g/min. The objective of this study was to remove the maximum amount of free fatty acids (FFA) and, so, to increase the tocopherol ...
