FCC catalyst stripping method. |
摘要 |
<p>A method and apparatus for improving the stripping of hydrocarbons from catalyst particles in a fluidized catalytic cracking (FCC) unit. A stripper vessel is located directly adjacent the exhaust barrel of a separator and immediately begins stripping hydrocarbon from catalyst particles. The stripper is sealed at the catalyst exit by a catalyst seal pot, with the drain sized to permit only a portion of catalyst flow to pass therethrough, with the remainder catalyst overflowing the seal pot. A short contact time stripper and catalyst particle deflector reduce the «residence» time of hydrocarbons with catalyst particles.</p> |
