Cubic average boiling point (CABP) and Mean Average Boling Points (MeABP) can be calculated as follows. C A B P = ∑ x i volume T b i 1 / 3 3. M e A B P = M A B P + C A B P / 2. For petroleum streams, volume, weight, or mole fractions of the components are not usually known. In this case, VABP is calculated from standard distillation (ASTM D86 ...

Gel- permeation (molecular sieve) chromatography The basic principle of this method is to use dextran containing materials to separate macromolecules based on their differences in molecular sizes. This procedure is basically used to determine molecular weights of proteins, and to decrease salt concentra-Figure 1. Column chromatography.

May 01, 2009 Molecular distillation of bio-oil at 70 C, 100 C and 130 C were investigated in this study to explore the effects of the evaporation temperature on the separation of compounds. The bio-oil was divided into three fractions: light, middle and heavy fractions. All samples were kept under − 4 C in the refrigerator.

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 is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below. It’s considered as the safest mode of separation and to purify the thermally unstable molecules and related compounds with low volatility and elevated boiling point. Wiped film short path molecular ...

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. The effects of feed ...

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 ...

The resulting mixed product is often used without purification, but if high-quality monoglycerides are desired, these can be obtained by molecular distillation of the mixed product. Monoglycerides have important applications in the food-processing industry for the stabilization of both water-in-oil (e.g., margarine) and oil-in-water (e.g ...
