A process for producing olefins, comprising: dehydrogenating a first n-alkane in a first dehydrogenation reaction zone to produce a first effluent comprising at least one of a first n-olefin or a first diolefin; dehydrogenating at least one of a first isoalkane or a second n-alkane in a second dehydrogenation reaction zone distinct from the first dehydrogenation reaction zone to produce a second effluent comprising at least one of a first isoolefin, a second n-olefin, or a second diolefin; compressing the first effluent; compressing the second effluent; feeding the first and second effluents to a common separation train to separate the first and second effluents into two or more fractions, wherein each of the first and second dehydrogenation reaction zones comprise two reactors, the process further comprising: operating one reactor in each of the reaction zones in a dehydrogenation cycle; operating one reactor in a regeneration cycle; and operating one reactor in a purge or evacuation/reduction cycle, wherein operation of the reactors in the dehydrogenation cycle is staggered, such that the purge cycle, regeneration cycle, or evacuation/reduction cycle of the reactors do not overlap, and wherein the first n-alkane is selected from the group consisting of propane and n-butane, wherein the second n-alkane is different from the first n-alkane and wherein the at least one of a first isoalkane or a second n-alkane is selected from the group consisting of isobutane, n-butane, or a mixture comprising isobutane and n-butane. dehydrogenating a first n-alkane in a first dehydrogenation reaction zone to produce a first effluent comprising at least one of a first n-olefin or a first diolefin; dehydrogenating at least one of a first isoalkane or a second n-alkane in a second dehydrogenation reaction zone distinct from the first dehydrogenation reaction zone to produce a second effluent comprising at least one of a first isoolefin, a second n-olefin, or a second diolefin; compressing the first effluent; compressing the second effluent; feeding the first and second effluents to a common separation train to separate the first and second effluents into two or more fractions, wherein each of the first and second dehydrogenation reaction zones comprise two reactors, the process further comprising: operating one reactor in each of the reaction zones in a dehydrogenation cycle; operating one reactor in a regeneration cycle; and operating one reactor in a purge or evacuation/reduction cycle, wherein operation of the reactors in the dehydrogenation cycle is staggered, such that the purge cycle, regeneration cycle, or evacuation/reduction cycle of the reactors do not overlap, and wherein the first n-alkane is selected from the group consisting of propane and n-butane, wherein the second n-alkane is different from the first n-alkane and wherein the at least one of a first isoalkane or a second n-alkane is selected from the group consisting of isobutane, n-butane, or a mixture comprising isobutane and n-butane. operating one reactor in each of the reaction zones in a dehydrogenation cycle; operating one reactor in a regeneration cycle; and operating one reactor in a purge or evacuation/reduction cycle, wherein operation of the reactors in the dehydrogenation cycle is staggered, such that the purge cycle, regeneration cycle, or evacuation/reduction cycle of the reactors do not overlap, and wherein the first n-alkane is selected from the group consisting of propane and n-butane, wherein the second n-alkane is different from the first n-alkane and wherein the at least one of a first isoalkane or a second n-alkane is selected from the group consisting of isobutane, n-butane, or a mixture comprising isobutane and n-butane. <EOS>
