Wikipedia has similar article

Wikipedia also has an article on the Fenske equation and I contributed to that article very extensively. I created this CZ article essentially by rewriting the WP article, reformatting it and expanding it. I did the rewrite in my CZ sandbox before creating this article. This CZ article is now much better than the one in Wikipedia.

The diagram in this article is not the same as the one in Wikipedia. I drew this article's diagram and uploadeded it into CZ. I also drew the diagram in the Wikipedia article. - Milton Beychok 13:05, 17 February 2008 (CST)

Equation explanation

It would appear that the equation explanation may be a bit off:

Does this part:

Xd = mole fraction of more volatile component in the overhead distillate Xb = mole fraction of more volatile component in the bottoms product

mean what it says, ie the mole fraction of the same compound, at two locations, or is this a typo from cut and paste? One of the references listed suggests that Xd and Xb are the mole fraction targets (desired level of purify) of the more volatile and the less volatile chemicals, respectively.

Also, I simple graph showing how N varies as Xd (and/or Xb) changes from values near to 1.0 and approaching 0.0 might be a nice graphic for discussion in the article. Or, at what mole fraction is N a minimum? (I suppose 1.0, neat product) David E. Volk 19:59, 21 October 2009 (UTC)

Also, doesn't the mole fraction of the feedstock come into play somehow for # of theoretical plates needed?
