ABSTRACT:
A method for the fractional distillation of a mixture of at least two compounds with different boiling points, a rising flow of vapor is brought into intimate contact with a descending flow of liquid obtained within a column (1) by the partial condensation of the flow of vapor itself by heat exchange with a cooled surface which extends through a filling (37).
