METHOD AND DEVICE FOR OBTAINING 1,3 PURE BUTADIENE FROM 1,3 RAW BUTADIENE BY DISTILLATION

摘要

The invention relates to a method for obtaining 1.3 pure butadiene from 1.3 raw butadiene by distillation. Said method is carried out in a separating wall column, wherein a separating wall is arranged in the longitudinal direction of the column in such a manner that it forms a common upper column area, a common lower column area, a feed part and a removal part.
