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 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 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 are disclosed. A C4 feed stream containing isobutylene and other C4 hydrocarbons is fed into a reactor unit for producing MTBE. The effluent of the reactor unit comprising MTBE is further processed to produce a MTBE product stream that comprises at least 90 wt. % MTBE. At least a portion of the MTBE product stream is then recycled back to the reactor unit.

Abstract: Systems and methods for processing a C3 and C4 hydrocarbon mixture have been disclosed. The C3 and C4 hydrocarbon mixture is separated to remove propane from C4 hydrocarbons. The resulting C4 hydrocarbons are then processed in an isomerization unit to produce additional isobutane. The isobutane of the isomerization unit effluent is dehydrogenated in a dehydrogenation unit to produce isobutene. The resulting isobutene is reacted with an alkanol to produce an alkyl tert-butyl ether.

Abstract: A method of producing methyl tertiary butyl ether (MTBE) and propylene is disclosed. The method involves the use of a crude C4 stream and the integration of a MTBE synthesis process and a cracking process. The method may include processing a byproduct stream from an MTBE synthesis unit to produce high purity olefin streams for an olefins conversion technology unit.

Abstract: Systems and methods of dehydrogenating a hydrocarbon in a fixed bed dehydrogenation unit. A method for dehydrogenating a hydrocarbon is applied to a fixed bed reactor. The hydrocarbon flows to a fixed bed reactor to be dehydrogenated in presence of a catalyst in the fixed bed reactor. The catalyst in the fixed bed reactor is then regenerated. The period for dehydrogenation, the period for catalyst regeneration and the period for total slack time are controlled such that total slack time is less than both half of the period for dehydrogenation and half of the period for regeneration. One of the advantages of the process comes from optimization of the slack time, thereby increasing the catalyst utilization rate and number of reactors concurrently online.
