  • Apparatus for the separation of fluid cracking catalyst particles from gaseous hydrocarbons
    Patent number: 4692311
    Abstract: Catalyst and hydrocarbon vapors are separated in a cyclone zone attached to the discharge of a riser cracking operation. A vortex stabilizer separating the cyclone zone from a stripping zone allows stripping gas from the stripping zone to be passed upwardly into the cyclone zone countercurrent to the downward flow of catalyst, thereby improving the separation and stripping of gaseous hydrocarbons from separated catalyst. The combined cyclone-stripping zone reduces catalyst hydrocarbon contact time, thereby improving gasoline yield and olefin content, decreasing gas make, and reducing coke deposits.
    Type: Grant
    Filed: February 10, 1984
    Date of Patent: September 8, 1987
    Assignee: Shell Oil Company
