  • Fluidized bed reactor with back-mixing for dehydrogenation of light paraffins
    Patent number: 8282886
    Abstract: An improved process and system for the endothermic dehydrogenation of an alkane stream is described. The process and system for catalytic dehydrogenation comprise a back-mixed fluidized bed reactor. The alkane stream is dehydrogenated in a single reactor stage by contacting the alkane stream with a back-mixed fluidized bed of catalyst. Deactivated catalyst is withdrawn from the back-mixed fluidized reactor and heated to produce hot regenerated catalyst. The hot regenerated catalyst is returned to the back-mixed fluidized bed reactor at a rate sufficient to maintain the back-mixed fluidized bed reactor at substantially isothermal conditions.

    Abstract: One exemplary embodiment can be a separation zone for separating a plurality of naphtha components. The separation zone can include first and second columns. The first column may include a dividing imperforate wall with one surface facing a feed and another surface facing a side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Also, the second column can communicate with the first column so as to provide a feed to or receive a feed from the first column. Generally, the second column is non-divided. The separation zone may provide at least four product streams.

  • FERMENTATION METHOD
    Publication number: 20120156739
    Abstract: This invention relates to the integration of an ammonia production process with a fermentation process to produce products such as alcohols and/or acids in addition to ammonia. In a specific embodiment, a natural gas stream comprising methane is passed to a reforming zone to produce a substrate comprising CO and H2. The substrate is next passed to a bioreactor containing a culture of one or more microorganisms and fermenting the culture to produce one or more fermentation products comprising alcohols and/or acids and an exhaust stream comprising CO2, and H2. The exhaust stream can then be passed to a separation zone to remove at least a portion of the CO2 and produce a purified exhaust stream comprising H2 which is then passed to an ammonia production zone and is used to produce ammonia.

  • Integrated production of FCC-produced C3 and cumene
    Patent number: 8128895
    Abstract: Processing schemes and arrangements are provided for obtaining propylene and propane via the catalytic cracking of a heavy hydrocarbon feedstock and converting the propylene into cumene without separating the propane from the propane/propylene feed stream. The disclosed processing schemes and arrangements advantageously eliminate any separation of propylene from propane produced by a FCC process prior to using the combined propane/propane stream as a feed for a cumene alkylation process. A bottoms stream from the cumene column of the cumene alkylation process can be used and an absorption solvent in the FCC process thereby eliminating the need for a transalkylation reactor and a DIPB/TIPB column.
