METHOD AND DEVICE FOR TREATING A C4 FRACTION |
摘要 |
The invention relates to a method for treating a C4 fraction, comprising the following steps: extractive distillation (I), selective hydrogenation on a heterogeneous catalyst (II), a stream of crude 1,3-butadiene resulting from steps (I) and (II); and distillation of said stream of crude 1,3-butadiene i n order to obtain pure 1,3-butadiene (III). Steps I and II take place in a single column or in thermally coupled columns and step III is carried out in a second column. |
