  • Processes for increasing an octane value of a gasoline component
    Patent number: 11066345
    Abstract: Processes for increasing an octane value of a gasoline component by dehydrogenating a stream comprising C7 hydrocarbons and methylcyclohexane in a first dehydrogenation zone to form an intermediate dehydrogenation effluent, and then dehydrogenating the intermediate dehydrogenation effluent in a second dehydrogenation zone to form a C7 dehydrogenation effluent. The C7 dehydrogenation effluent has an increased olefins content compared to an olefins content of the intermediate dehydrogenation effluent. The first dehydrogenation zone is operated under conditions to convert methylcyclohexane to toluene and minimize cracking reactions. The intermediate dehydrogenation effluent may be heated before being passed to the second dehydrogenation zone.

  • Process and apparatus for reducing pressure in a flue gas stream
    Patent number: 11042170
    Abstract: A process and apparatus for reducing pressure of a flue gas stream including passing a pressurized flue gas stream to a vessel and through a bed of particulates in the vessel to reduce the pressure of the flue gas stream. The flue gas passes from the vessel at a lower pressure than at which it entered. The bed of particulates is disposed in the vessel between the outlet end of the inlet conduit and the inlet end of the outlet conduit. If deposits develop in the bed of particulates, the particulates can be replaced with fresh particulates to avoid excessive pressure drop. Data may be received from a stream in fluid communication with the foregoing process and apparatus.
