Title: RISER SEPARATION SYSTEM
Abstract:
The present disclosure is directed to an apparatus and a compact riser separation system for separating a gaseous mixture from a stream of particles entering from a central riser reactor used for cracking a hydrocarbon feed with the stream of particles. The apparatus provides improved gas solid separation efficiency and maximize containment of the hydrocarbon and minimize residence time in the separation system and thereby minimizing undesired post riser cracking reactions.
