Abstract:
Systems for purifying 1,3-butadiene are provided. An exemplary system includes a first distillation column, a second distillation column, and interconnections between the first and second distillation columns. A first interconnection can feed a liquid stream from the second distillation column to the first, while a second interconnection can feed a gas stream from the second distillation column to the first. Processes for purifying 1,3-butadiene are also provided.
