Abstract:
The process to recover heat in oxidative dehydrogenation of butene to butadiene is presented. The process utilizes heat recovered in oxidative dehydrogenation of butene to butadiene to generate steam. The process utilizes the circulated water stream generated in oxidative dehydrogenation of butene to butadiene for steam generation. A feedstream comprising butene is mixed with steam and preheated air at the inlet of the oxidative dehydrogenation reactor.

Claim (Index 15):
A process for steam generation by heat recovery in oxidative dehydrogenation of butene to butadiene comprising:\n passing a feedstream comprising butene along with steam and preheated air to an oxidative dehydrogenation reactor; oxidatively dehydrogenating the feed stream over a dehydrogenation catalyst in the oxidative dehydrogenation reactor to form a product stream; passing the product stream to a quench tower to generate cooled product stream and a water stream; passing the water stream to a disengaging drum to generate steam, a circulating water stream, and a draw-off stream comprising hydrocarbons and oxygenates; removing the draw-off stream in the disengaging drum; and passing the steam to the oxidative dehydrogenation reactor.
