Abstract
Houdry lumps can be reduced by controlling the reactors in a fixed bed dehydrogenation process for producing olefins according to defined rules. A programmable logic controller can apply the rules to the operation of the dehydrogenation unit and control the operation of individual reactors according to the rules. By doing so, the performance of dehydrogenation units can be improved without adding any heat generating inerts, such as CuO-α alumina For example, the dehydrogenation units can be operated according to combinatorics in the programmable logic controller such that the farthest two reactors in the dehydrogenation unit never operate in parallel in the dehydrogenation or air regeneration steps.
