ABSTRACT:
A distillable liquid containing non-volatile impurities is freed of those impurities by boiling the liquid to form vapors of the liquid, passing the vapors through a packed column heated to a temperature such that liquid entrained in the vapors is completely vaporized and the non-volatile impurities remain in the packed column, and condensing the vapors from the column.
