CYCLONE FOR SEPARATING CATALYST PARTICLES FROM GASEOUS HYDROCARBONS |
摘要 |
Catalyst and hydrocarbon vapors are separated in a cyclone zone attached to the discharge of a riser cracking operation. Vortex stabilizing means separating the cyclone zone from a stripping zone allows stripping gas from said stripping zone to be passed upwardly into said 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. |
