The separation factor or permselectivity reflects the capability of a membrane to separate one gas from another.
The kinds of groups on PS membrane surface play an important role in separation factor and the separation factor was in the order as follows: –COOH > –OH> phenyl.
Under these conditions, the experimental separation factor of SA and ASA was 10.24 ± 1.06%, which was close to the predicted separation factor.
As in repetitive extraction, the larger that the separation factor is for a pair of components, the shorter will be the column necessary to resolve them.
The constant separation factor (CSF) design strategy, with the same separation factor values for each stage in the cascade, was compared with the variable separation factor (VSF) strategy in which the separation factor values for each stage are optimized independently to minimize the energy consumption.
The total flux greatly increases whereas separation factor falls with increasing CA loading.
The performances of membranes were compared in terms of flux, permselectivity, enantioselectivity and separation factor.
Fundamental concepts including separation factor, relative volatility, vapor-liquid equilibrium (VLE), and activity coefficients are presented.
The separation factor was low, due to similar solubilities of the vitamin ester and the oil.
Meanwhile, the distribution coefficient and separation factor were calculated and discussed in detail.
The results indicate that H218O/H216O isotopomeric separation factor increases through using PVDF nanofibrous membrane.
