  • Patent number: 10647623
    Abstract: Processes and an apparatus for reducing heavy oxygenate recycle for an MTO reaction zone. After separating product and water from the MTO reaction effluent, an oxygenate rich stream is passed to a conversion zone in which methanol in the oxygenate rich stream is converted into DME. A DME rich stream is separated from heavy oxygenates and is recycled back to the MTO reaction zone. The conversion zone may include a reactive distillation column, or the conversion zone may include a reactor vessel and a separate separation vessel.

  • Patent number: 10589264
    Abstract: A method of controlling the regeneration of spent catalyst from an oxygenate-to-olefin reaction zone in order to provide a partially regenerated catalyst. The partially regenerated catalyst has between 1 to 4, or 1 to 3, or, 2 to 3 wt % coke. The regeneration is controlled by adjusting a ratio of air to recycled flue gas in the combustion gas passed to the regeneration zone. CO in the flue gas is removed in a CO oxidation zone which receives oxygen to oxidize CO to CO2.

  • Patent number: 10538466
    Abstract: A process is presented for the production of butadienes. The process includes the separation of oxygenates from the product stream from an oxidative dehydrogenation reactor. The process includes quenching the product stream and solvent and oxygenates from the product stream. The oxygenates are stripped from the solvent with an inert gas to reduce the energy consumption of the process, and the solvent is recycled and reused in the process.

  • Patent number: 10526259
    Abstract: A process is presented for the oxidative dehydrogenation of butenes to butadienes. The process includes the use of parallel reactors, wherein the reactors are operated at different pressures. A butene feedstream is split into several portions wherein each portion is passed to a different reactor. Each reactor generates an effluent stream, and the effluent stream is cooled to generate steam for use in a lower pressure reactor.
