METHOD FOR RECOVERING CRUDE 1,3-BUTADIENE BY EXTRACTIVE DISTILLATION FROM A C4 CUT |
摘要 |
The invention relates to a method for recovering crude 1,3-butadiene by extractive distillation from a C4 cut, using a selective solvent in a separation column (TK). In said column, a partition wall (T) is located in the longitudinal direction of the column, forming a first sub-section (A), a second sub-section (B) and a lower common column zone (C). An extractive scrubber column (K) is connected upstream of the separation column.
