  • Patent number: 11186784
    Abstract: New/fresh catalyst is added to a dehydrogenation unit and aged catalyst is removed from the dehydrogenation unit on a continuous or semi-continuous basis while the dehydrogenation unit is in operation. The conversion achieved by the higher activity catalyst results in the production rate of olefin product being maintained at near start-of-run production for longer, with a slower rate of decline. The higher activity catalyst extends run time, reduces feed consumption for each unit of olefin product, and minimizes fresh catalyst expenses.

  • Patent number: 11180703
    Abstract: Improved processes for production of gasoline with 95 RONC including a C5-C6 isomerization zone, two C7 isomerization zones, and a reforming zone are described. The first and second C7 isomerization zones share a common stabilizer which strips off the chlorides and removes the light ends. The capital and operating costs of the processes are reduced through the elimination of one of the stabilizer columns and the associated condenser, receiver, trim cooler, and reboiler. The processes improve the RONC of the C7 isomerization product because unconverted methylcyclohexane is recycled back to the second C7 isomerization zone to be converted into dimethylcyclopentane.

  • Patent number: 11167258
    Abstract: In an FCC apparatus and process structured packing should be located at the very top of the stripping section in an upper region. The lower region below the structural packing may be equipped with fluidization equipment such as stripping media distributors and one or more gratings. This arrangement enables stripping of entrained hydrocarbons off the incoming catalyst immediately upon entry into the stripping section allowing the entrained hydrocarbon to exit the stripping section with minimized residence time to minimize post-riser cracking. Revamp of stripping sections with tall stripping sections should conducted in this way to improve performance and reduce down-time for equipment installation.

  • Patent number: 11167239
    Abstract: A process is provided for increasing the recovery of high-purity hydrogen from a steam cracking process in situations where byproduct methane yield is high relative to hydrogen. After a hydrocarbon gas stream is sent through a cold box and demethanizer, a small proportion of methane is sent through a pressure swing adsorption unit separately from a gas stream that contains hydrogen to increase high-purity hydrogen recovery by about 6%.

  • Patent number: 11136514
    Abstract: The process and apparatus enables purification of a recycle hydrogen gas stream from hydroprocessing biorenewable feedstocks. The recycle gas stream is fed to a methanator reactor to hydrogenate carbon monoxide in the gas stream to water and methane. Other acid gases can be removed by scrubbing preferably upstream of the methanator. Removal of carbon monoxide omits the need for a hydrogen purge stream to avoid carbon monoxide accumulation and enables use of the hydrogen for a downstream hydroisomerization reaction.
