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 propylene using an MTBE synthesis raffinate are disclosed. An MTBE synthesis raffinate stream first passes through a molecular sieve to separate n-butane and isobutane from the rest of C4 hydrocarbons of the MTBE synthesis raffinate. The 1-butene in the rest of C4 hydrocarbons of the MTBE synthesis raffinate is then isomerized to form 2-butene. Therefore, the concentration of 2-butene in the subsequent propylene production process increases due to the separation of n-butane and isobutane and the isomerization of 1-butene, resulting in an improved reaction rate and reaction efficiency for propylene production.

Abstract: A method of producing a fuel additive includes passing a feed stream comprising C4 hydrocarbons through a first hydrogenation unit producing a first process stream; passing the first process stream through a distillation unit; withdrawing a 2-butene stream from the distillation unit: passing the 2-butene stream through a second hydrogenation unit producing a 1-butene stream; passing at least a portion of the 1-butene stream through a separation unit; and passing the 1-butene stream through a hydration unit producing the fuel additive.

Abstract: Systems and methods for integrated glycerol carbonate and/or urea production. This disclosure pertains to development of a process for production of glycerol carbonate and/or urea from ammonia, carbon dioxide and glycerol. The process integrates glycerol carbonate production into a urea production process. The urea produced in the production facility may be used to produce glycerol carbonate by reacting urea with glycerol. The ammonia generated by glycerol carbonate production may be recycled back to urea production. Unreacted urea from the glycerol carbonate production may be separated and recycled to the urea product stream. The systems and methods can reduce the cost for urea production and increase product value of the excessive glycerol produced from other chemical plants.
