Abstract
An improved packed column distillation system, which may be particularly advantageous for use with cryogenic distillation such as the cryogenic distillation of air, wherein external heat is provided at the column wall, especially at a stripping section of the column, to vaporize liquid formed on the inner surface of the column wall resulting in improved separation efficiency with lower packed bed height.
