Abstract

A procedure for the recovery of butadiene from mixtures thereof with other C4 hydrocarbons by means of extractive distillation in the presence of a polar solvent and subsequent desorption of the solvent, characterized in that a fatty solvent recovered from the extractive distillation zone is introduced, optionally after partial exhaustion, in a first desorption zone operated at a lower pressure than the extractive distillation zone, a stream of butadiene-enriched steam is recovered from said desorption zone, it is returned to the extractive distillation zone A part of said vapor stream after compression, another part of said vapor stream, after compression, is introduced into a second desorption zone and butadiene is recovered from the said second desorption zone.
