PROCESS AND APPARATUS FOR THE SEPARATION OF THE CATALYST USING A CYCLONE IN A FCC PROCESS.

摘要

An apparatus and process for the separation of solids from gases in a mixture improves separation efficiency by imparting a swirl motion to the mixture in a first angular direction to centripetally separate the heavier solids from the lighter gases in conduit and orienting the inlet of the cyclone such that trajectory of the mixture is away from the center of the cyclone. The desired trajactory may be gained by imparting a opposite swirling angular direction to the mixture in a separation vessel with respecto to the cyclone or having the cyclone arranged tangentially with the vessel so that the cyclone and separation vessel share a common tangential sidewall. The apparatus and method incorporates a greater proportion of the mixture entering the cyclone into its vortex to further enhance separation between the solids and gases. Further separation efficiency is added by tangentially directing the mixture into the cyclone.
