Abstract: A method for processing pentanes obtained from a DIB unit is disclosed. The process can include separating a first stream containing pentanes obtained from a DIB unit, in a separation column to obtain a second stream comprising iso-pentane and a third stream comprising n-pentane and neo-pentane; and subjecting the third stream to a butane isomerization unit producing a fourth stream containing iso-pentane, n-pentane, and neo-pentane.

Abstract: This disclosure describes one or more trays for use in distillation columns. The trays include a plate having a plurality of through holes that extend between a first surface of the plate and a second surface of the plate. The plurality of through holes include a first set of through holes each having substantially a first diameter and a second set of through holes each having substantially a second diameter that is different from the first diameter. The trays also include a weir coupled to the plate and extending from the first surface. The weir is positioned between the first set of through holes and the second set of through holes.

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.
