>>14121347Technically reflux is that stream that you return to the distillation column. It usually comes off the top of the column as a vapor and is returned in liquid form (ie condensed) - near the top of the column.
As usual, there are always exceptions.
I think moonshiners like the term refluxing and chemical engineers use distillation or more commonly fractionation .
Its also used as a verb ie "this reflux action enhances separation of whatever you are trying to distill (separate)."
Probably didnt help. Now you have three terms to be confused about.
