Abstract:
The present disclosure provides methods and systems for producing 1,3-butadiene. In certain embodiments, the present disclosure provides methods for the extractive distillation of 1,3-butadiene in a divided wall distillation column having a first region, a second region and a combined bottom region. An exemplary method can include feeding a C 4  hydrocarbon stream and a first solvent into the first region and removing a first stream from the first region. The method can further include feeding a second solvent into the second region, removing a second stream that includes 1,3-butadiene from the second region, and removing a third stream from the combined bottom region.

Claim (Index 8):
The method of  claim 6 , wherein the C 4  hydrocarbon stream is split into two or more streams prior to feeding the C 4  hydrocarbon stream into the first region of the distillation column.
