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.

Abstract: Systems and methods for producing heat and an oxidant for an endothermic chemical production process are disclosed. At least some process heat is recovered from (1) a hot gas including hot gas from a waste air vent of an MTBE production unit and/or (2) a catalyst regeneration process into a combustion gas stream. The combustion gas stream is further used in a steam reformer and/or a cracker for providing an oxidant and at least some heat.

Abstract: Systems and methods for producing MTBE without using a catalytic distillation column or a super fractionator have been disclosed. An optimum volume of methanol stream required to maximize MTBE production and reduce slippage of isobutylene to minimum acceptable values together with a crude C4 stream are flowed into a primary reaction unit that comprises a first reactor and a second reactor in parallel configured to produce maximum values of final MTBE volumes under higher or equal established purity commercial quality specifications levels. The combined effluent from the first reactor and the second reactor is split to form a first portion, a second portion and a third portion. The first portion is flowed to a third reactor configured to produce additional MTBE. The second portion is combined with an effluent from the third reactor for further separation. The third portion is recycled to the first reactor and/or second reactor.

Abstract: Systems and methods for processing a C3 and C4 hydrocarbon mixture have been disclosed. The C3 and C4 hydrocarbon mixture is first processed in an isomerization unit to isomerize n-butane to form isobutane. The resulting effluent stream from the isomerization unit comprising primarily isobutane and C3 hydrocarbons, collectively, is flowed into a separation unit configured to separate the effluent stream to form a C3 stream comprising C1 to C3 hydrocarbons and a C4 stream comprising primarily isobutane. The isobutane in the C4 stream is further dehydrogenated to form isobutene, which is further flowed into an MTBE synthesis unit as a feedstock for producing MTBE.
