1. A method of performing a fixed bed dehydrogenation process for producing olefins, the method comprising:
controlling at least three fixed bed dehydrogenation reactors configured to dehydrogenate a hydrocarbon to produce an olefin, wherein the controlling is performed such that a farthest two of the reactors, by distance, from each other are not operated simultaneously in either of dehydrogenation processing and catalyst regeneration processing.
