Abstract

See full text

The invention pertains to a method for converting butanediol into butadiene that is fed with a butanediol feedstock, where said method comprises at least an esterification step, a pyrolysis step, and a step for separation of the pyrolysis effluent comprising at least one section for cooling said pyrolysis effluent and producing a liquid pyrolysis effluent and a steam pyrolysis effluent and a gas-liquid washing section that is fed at the top with a fraction of the butanediol diester effluent obtained from the esterification step and at the bottom with the steam pyrolysis effluent, where said section produces a butadiene effluent at the top and a washing effluent at the bottom.
