  • Patent number: 10787400
    Abstract: The present disclosure provides oxidative coupling of methane (OCM) systems for small scale and world scale production of olefins. An OCM system may comprise an OCM subsystem that generates a product stream comprising C2+ compounds and non-C2+ impurities from methane and an oxidizing agent. At least one separations subsystem downstream of, and fluidically coupled to, the OCM subsystem can be used to separate the non-C2+ impurities from the C2+ compounds. A methanation subsystem downstream and fluidically coupled to the OCM subsystem can be used to react H2 with CO and/or CO2 in the non-C2+ impurities to generate methane, which can be recycled to the OCM subsystem. The OCM system can be integrated in a non-OCM system, such as a natural gas liquids system or an existing ethylene cracker.

The ethane oxidation product is fed to a series of absorption towers using a n-butane solvent that remove the inert components as well as purifying the ethylene from the product. A first absorption tower uses n-butane as a solvent to absorb both the ethane and ethylene, allowing for inert gasses to be removed from the stream. An ethylene-rich side stream from this tower is sent to an ethylene purification tower where ethylene is purified using n-butane solvent. The bottom stream from the first absorption tower is then sent to an intermediate ethylene recovery tower where crude ethylene is purified, and the overhead ethylene stream being sent to the ethylene purification tower.

  • Publication number: 20130131417
    Abstract: One example method of the invention includes a process for producing an olefin comprising the steps of communicating a feed stream that comprises a paraffin to a distillation section, communicating a distillation section output stream to a reactor and reacting the distillation section output stream in the reactor to produce a reactor output stream comprising an olefin. A splitter feed stream that is in communication with and downstream from the reactor output stream is communicated to an olefin splitter, and a splitter output stream is communicated to a heat pump compressor. A heat pump compressor output stream is communicated to the distillation section and heat is used from the heat pump compressor output stream to reheat a distillation section stream that contains unreacted paraffin.

  • Patent number: 8349263
    Abstract: An improved process for the production of olefins, and in particular for separation of olefins produced by a dehydrogenation process from paraffin feed stocks, is provided. A high pressure product splitter is used to separate olefins produced in a dehydrogenation plant from residual paraffin feed stocks. The use of a high pressure splitter to separate olefin products from paraffin feed stocks allows for recovery of a high purity olefin product with lower energy consumption compared to prior art processes. The process is particularly suited to separation of propylene from propane.

  • Patent number: 8288604
    Abstract: A method of rapid methylation of an aromatic compound or an alkenyl compound, which is capable of obtaining an aromatic compound or an alkenyl compound labeled with a methyl group or a fluoromethyl group under a mild condition rapidly in high yield using an organic boron compound whose toxicity is not so high as a substrate. A kit for preparing a PET tracer and a method of producing a PET tracer can be practiced using the rapid methylation method. In an aprotic polar solvent, methyl iodide or X—CH2F (wherein X is a functional group which can be easily released as an anion), and an organic boron compound in which an aromatic ring or an alkenyl group is attached to boron are subjected to cross-coupling in the presence of a palladium(0) complex, a phosphine ligand, and a base.

    Abstract: The invention is a method for processing a mixture containing water, 3-methyl-1-butene and at least one other methylbutene. The method comprises primary distillation of the mixture, giving a gaseous primary overhead product containing methylbutene and water and a water-free primary bottom product containing 3-methyl-1-butene; condensation of the gaseous primary overhead product so as to give a condensate comprising a liquid aqueous phase and a liquid organic phase; separation of the condensate into a liquid aqueous phase and a liquid organic phase; discharge of the liquid aqueous phase; recirculation of the organic phase to the primary distillation; and finally secondary distillation of the water-free primary bottom product from the primary distillation so as to give a secondary overhead product comprising 3-methyl-1-butene and a secondary bottom product. The secondary overhead product obtained has a purity which enables it to be used directly as monomer or comonomer for preparing polymers or copolymers.
