ABSTRACT:
An improved fractional distillation column, especially adapted for use in fractional distillation of heat-sensitive materials under low pressure, is described. The improvement comprises a partial condenser disposed above the packing in the column. The partial condenser is a grid of hollow tubes mounted horizontally and extending through the side walls of the column. Heat exchange fluid at controlled temperature lower than the outer condensing vapor temperature is circulated through the tubes. The outer surfaces of the tubes within the column are provided with drip sites to facilitate uniform distribution of condensed liquid falling from condenser tubes to the packing below.
