The first is the separation factor, which is a number greater than 1.
2.
If zeotropic blends are used, it is common to select mixtures with small separation factors ( so called near-azeotropic mixtures ).
3.
The separation factor at the limiting temperature is still very small, and thus the differences between liquid and vapor composition is too small to be of use for distillation.
4.
These are commonly used in industry for the processing of metals such as the lanthanides; because the separation factors between the lanthanides are so small many extraction stages are needed.
5.
An alternative procedure is anion exchange with an appropriate resin in nitric acid, which can result in a separation factor of 1, 000, 000 for radium and actinium vs . thorium in a two-stage process.
6.
Uranium-235 makes up only about 0.72 % of natural uranium, so the separation factor of any uranium enrichment process needs to be higher than 1250 to produce 90 % uranium-235 from natural uranium.
7.
They calculated that a liquid thermal diffusion plant capable of producing 1 kg per day of uranium enriched to 90 % uranium-235 would require 21, 800 columns, each with a separation factor of 30.7 %.
8.
Let A, B be two disjoint sets of points in \ mathbb { R } ^ d, R ( X ) denote the axis-aligned minimum bounding box for the points in X, and s > 0 denote the "'separation factor " '.
