Abstract
Processes and apparatuses for the production of butadienes are provided. In an embodiment, a process for production of butadienes includes passing a reactor feed stream comprising a hydrocarbon stream comprising butene, a steam stream and a oxygen rich stream to a dehydrogenation reactor. The reactor feed stream is oxidatively dehydrogenated in the dehydrogenation reactor in presence of an oxidative dehydrogenation catalyst to provide an effluent stream comprising butadiene. The effluent stream is cooled in a quench tower to provide a cooled effluent stream and a bottoms water stream. The cooled effluent stream is passed to an aldehyde scrubber to provide a scrubbed effluent stream and a spent water stream comprising aldehydes. A first portion of the bottoms water stream is passed from the quench tower to the aldehyde scrubber.
