Abstract
Processes and systems for producing olefins, including: dehydrogenating a first n-alkane to produce a first effluent; and dehydrogenating at least one of a first isoalkane or a second n-alkane to produce a second effluent. The first and second effluents may be compressed and fed to a common separation train to separate the effluents into two or more fractions. In some embodiments, each of the first and second dehydrogenation reaction zones may include two reactors, one reactor in each of the reaction zones operating in a dehydrogenation cycle, one operating in a regeneration cycle, and one operating in a purge or evacuation/reduction cycle. Operation of the reactors in the dehydrogenation cycle is staggered, such that the purge cycle, regeneration cycle, or evacuation/reduction cycle of the reactors may not overlap.
