Abstract: Methods of and systems for producing an olefin are disclosed. A paraffin is dehydrogenated to produce a mixture comprising the olefin and unreacted paraffin. The mixture is then fed to an extractive distillation unit that uses soybean oil as a solvent to extract at least some n-butane from the mixture.

Abstract: System and method for producing 1-butene are disclosed. The method includes dehydrogenating butane to form a mixture comprising butene isomers. 1-butene is separated from the mixture using a system that includes a membrane. The system also includes an isomerizing unit for isomerizing cis-2-butene and trans-2-butene to form additional 1-butene.

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.
