  • Publication number: 20160368840
    Abstract: A method of oxidatively dehydrogenating a n-butenes to butadiene includes oxidatively dehydrogenating dehydrogenation reactant in a first adiabatic, catalytic reaction zone to provide a first-stage effluent stream enriched in butadiene at a first-stage effluent temperature above the first-stage inlet temperature, cooling the first-stage effluent stream in a first heat transfer zone to a second-stage inlet temperature lower than said first-stage effluent temperature to provide a second gaseous feed stream comprising superheated steam, n-butene and butadiene, wherein the second stage inlet temperature is lower than said first stage effluent temperature and oxidatively dehydrogenating n-butene in the second stream to provide a product stream further enriched in butadiene at a second stage effluent temperature above said second-stage inlet temperature. The first reaction zone temperature rise and the second reaction zone temperature rise are at least 200° F. (111° C.

  • Patent number: 9399603
    Abstract: A process is presented for increasing the conversion efficiency of oxygenates to olefins. The conversion of oxygenates recycles unconverted oxygenates and oxygenate by-products to a second reactor unit. The present of oxygenate by-products decreases the efficiency of the methanol to olefins reaction, and passing recycled oxygenates to a second reactor unit maintains the methanol to olefins conversion efficiency while converting the by-products in a secondary zone.

  • Publication number: 20150329442
    Abstract: A process for the production of butadiene is presented. The process converts a butane stream through dehydrogenation to process stream having butenes. The butenes are treated and separated from the process stream to generate an olefin rich stream. The olefin rich stream is passed to an oxydehydrogenation reactor for conversion to butadienes. The process utilizes a cold-box separation process for efficiently separating the process stream generated through dehydrogenation to separate light gases from the C4 hydrocarbon stream.
