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 11):
The method of  claim 6 , wherein the first stream is removed from the first region of the distillation column using the first condenser or wherein the second stream is removed from the second region of the distillation column using the second condenser.
