More Information
Summary:The invention concerns a process for the production of butadiene from an ethanol feed comprising at least 80% by weight of ethanol, comprising a step for conversion of ethanol to acetaldehyde, a step for the extraction of butadiene, a step for scrubbing gaseous by-products with water, a step for eliminating impurities and brown oils, a step for treating effluents, a first butadiene purification step, and a subsequent butadiene purification step, said ethanol feed being supplied to said butadiene extraction step, the arrangement of the steps and recycles allowing the recycles to be maximized and allowing the water and energy consumption to be minimized.
