Process for preparing butadiene from ethanol, including purification of a butadiene rich effluent by extractive distillation |
| abstract |
The present invention relates to a process for preparing butadiene from ethanol feedstock comprising the steps of: converting ethanol to butadiene; Distillation stage; Washing with water; Butadiene purification step comprising at least one section for separating 1-butene by extractive distillation and a final distillation section for separating the butene residue from the tower and the butadiene effluent from the top over which the overhead butadiene distillate is fed; And an effluent treatment step. |
