FEEDDISPERSION SYSTEM FOR FLUID CATALYTIC CRACKING UNITS AND PROCESS FOR FLUID CATALYTIC CRACKING.

摘要

b sealing system of the leg of the cyclone d describes a sealing system of cyclone separator leg suspended solids gas - solid.More specifically, the present invention relates to a system for selegem legs of two stages of cyclones in the series used in the process of fluid catalytic cracking (FCC)Comprising a configuration terminal, which makes use of a curve (31) of the long devoid of moving parts.That changes the direction of flow of the mass flow downward of catalyst in dense phase.In a plane orthogonal to the gas flow upward, which prevents the entry of gaseous phase into the interior of the leg (24), promoting an efficient sealing.Avoiding the "packaging" of the dense bed of particles.
