Thermal-Diffusion In An Ideal Column

An ideal thermal diffusion column in which the separation efficiency is 100% is defined. The separation theory of such a column has also been derived. In the illustration given, the inclined moving-wall column acts as an ideal column because its efficiency reaches 98%. However, due to other operating and design conditions, there may be some better column still to be developed. The best thermal diffusion column for certain separation conditions is related to the highest separation efficiency based on the ideal column definition.
