  • Publication number: 20100071410
    Abstract: The disclosed invention relates to a distillation process for separating two or more components having different volatilities from a liquid mixture containing the components. The process employs microchannel technology for effecting the distillation and is particularly suitable for conducting difficult separations, such as the separation of ethane from ethylene, wherein the individual components are characterized by having volatilities that are very close to one another.

  • Patent number: 5961815
    Abstract: The hydroconversion of heavy petroliferous stocks boiling mainly above 400.degree. F. is carried out in a distillation column reactor where concurrently a petroleum stream is fed into a feed zone; hydrogen is fed at a point below said feed zone; the petroleum stream is distilled and contacted in the presence of a cracking catalyst prepared in the form of a catalytic distillation structure at total pressure of less than about 300 psig and a hydrogen partial pressure in the range of 1.0 to less than 70 psia and a temperature in the range of 400 to 1000.degree. F. whereby a portion of the petroleum stream is cracked to lighter products boiling below the boiling point of the feed and products are distilled to remove a vaporous overhead stream comprising products mainly boiling below the boiling point of the feed and a liquid bottoms stream.

  • Patent number: 5925685
    Abstract: Catalytic distillation reactions are improved by having an inert condensing component present in the reaction which is boiling and condensing within the reaction which washes the catalyst in the system and, in the case of gaseous reactants, occludes a portion of the reactants to facilitate the reaction without unduly high pressures. The inert condensing component is boiling at the conditions within the reactor and is taken overhead for condensation and return as reflux. The inert condensing component may occlude the gaseous reactants allowing for better contact with the catalyst and provides the benefits of concurrent reaction and distillation, for example, the reaction of CO and H.sub.2 over a copper catalyst to produce methanol using propane as the inert condensing component.

  • Patent number: 5763714
    Abstract: A mixed aromatic stream is hydrotreated to remove olefins and fractionated to separate C.sub.9 + heavies in a distillation column reactor and the C.sub.8 and lighter material is fed to a selective adsorption unit where the para-xylene is removed. The para-xylene depleted raffinate therefrom may be subjected to isomerization to form additional para-xylene. The effluent from the isomerization can be fed to the distillation column reactor for hydrogenation of any olefins formed during the isomerization or directly to the adsorption unit.

  • Patent number: 5597476
    Abstract: A catalytic cracked naphtha is desulfurized with minimum loss of olefins and octane. The naphtha is fed to a first distillation column reactor which acts as a depentanizer or dehexanizer with the lighter material containing most of the olefins and mercaptans being boiled up into a first distillation reaction zone where the mercaptans are reacted with diolefins to form sulfides which are removed in the bottoms along with any higher boiling sulfur compounds. The bottoms are subjected to hydrodesulfurization in a second distillation column reactor where the sulfur compounds are converted to H.sub.2 S and removed. The lighter fraction containing most of the olefins is thus not subjected to the more harsh hydrogenation conditions of the second reactor.

  • Patent number: 5431888
    Abstract: A multi-purpose distillation column reactor is disclosed which may be used for the production of tertiary amyl methyl ether from the reaction of the isoamylenes contained in a light naphtha with methanol. Two reaction distillation zones are disposed above a stripping section. The stripping, in addition to removing the TAME product, also removes the C.sub.6 and heavier components. The first reaction distillation zone contains a hydrotreating catalyst for removing diolefins and mercaptans. The second distillation reaction zone contains an acid cation exchange resin for the etherification reaction and the entire column serves to fractionate the multiple component reaction system (reacts, inerts, products and contaminants) concurrently with the multiple reactions.

  • Patent number: 5421972
    Abstract: A method for removing soluble contaminants, such as acetonitrile, from a non-polar hydrocarbon stream into a polar water stream by countercurrent flow between an electrostatic field generated by a pair of parallel electrodes. The electrostatic field is modulated in strength to produce a dispersing, mixing, coalescing, and settling cycle that is effective to mix and separate the fluids.

  • Patent number: 5082481
    Abstract: A process for recovering hydrogen from a cracking effluent wherein a cracking effluent is compressed, and then at least a portion of the hydrogen is separated from the cracking effluent prior to cooling of the cracking effluent to remove lower-boiling components. The separation of hydrogen is preferably accomplished by passing the cracking effluent through at least one semi-permeable membrane.
