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 an extractive distillation unit and a membrane. The system also includes a isomerizing unit for isomerizing cis-2-butene and trans-2-butene to form additional 1-butene.
