== Fractional distillation separation details == 

 I agree that this might be too detailed (and technically worded) for this article. However, that was the only place relative volatility was mentioned, which seems like a relevant associated topic. I don't know what fields of study use that terminology to know whether they would be looking at this less technical article enough to want examples. But I do know the theoretical plate article is highly technical and provides no actual examples. On the other hand, fractional distillation is a common topic in college (and maybe even lower) that does not need those details. But the qualitative idea of needing more plates for separating materials that have closer boiling points is often discussed in lab texts and demonstrated, so it seems useful to have a single actual (quantitative) example of that idea here in the less technical article.
