Abstract
A method for producing butenes by the dehydrogenation of n-butane includes dehydrogenating the n-butane in a dehydrogenation zone and contacting material from the dehydrogenation zone with a solvent that is more selective to dissolve n-butane than butenes. The resulting fluid from the contacting is subjected to extractive distillation to produce (1) a stream comprising a solution of the n-butane and solvent and (2) a stream comprising the butenes.
