System for gas-solid separation and for stripping for fluidized-bed catalytic cracking units

摘要

This invention describes a new system for gas-solid separation and for stripping combined into a single so-called separation/stripping zone that is compact and thus contributes to the quality of the yields of the unit. This new system can be applied to FCC units and makes it possible to obtain very good separation effectiveness while reducing the contact time between the gas and the solid at the same time.
