Abstract:
A regeneration process and apparatus eliminates the need for an external chlorination recycle loop. The method and apparatus uses two-pass internal mixing of a chlorine compound input stream and drying gas to both mix and heat the chlorination gas before entering the chlorination zone. The only heat required for the process is a small amount for vaporizing the chlorine containing input stream to prevent the formation of chloride droplets. All other heat for the chlorination zone is supplied internally in the regeneration vessel.
Pneumatic Particulate Transport With Gravity Assisted Flow
A system for transporting particulate material uses a combination of nonmechanical valves and pneumatic and gravity transport to reduce breakage of particulate material. This system is particularly useful for the conveyance of catalyst particles where a lift conduit raises the particles from a low elevation to a relatively higher elevation. A particular advantage of the arrangement is the elimination of pneumatic conveyance through elbows to reduce pressure drop and eliminate churning of catalyst particles. The elbows are replaced with an impactless flow diverter that uses gravity assisted conveyance to eliminate or minimize the attrition resulting from pneumatic conveyance.

Abstract:
A method and apparatus for replacing particles in a process that transfers particles is disclosed. This invention employs a seal zone which is in communication with two zones of the process and in which particles that are being added to the process are purged. This invention allows particles to be replaced without reducing the normal rate of particle transfer through the process, which results in a savings in downtime costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

Abstract:
A separation process for improved separation of liquids containing finely divided suspended particles using multiple stacks of parallel angled interceptor plates which divide the separation vessel to provide an annular space between the parallel angled interceptor plates and the vertical wall of the separation vessel to thereby form an inlet manifold for the plates which manifold provides a uniform, uninterrupted flow to each stack of plates. The arrangement of plates also forms an outlet manifold which provides a uniform flow from each stack of plates and directs the liquid stream having a reduced level of finely divided suspended particles downward in the separation vessel to an exit in the lower end of the vessel. The feed liquid is introduced into the lower end of the separation vessel with an inlet distributor which initially directs at least a major portion of the feed liquid in a generally downward direction to effect a primary separation prior to being introduced into the stacks of parallel angled interceptor plates. The introduction of the feed liquid and the exit of the separated product streams from the lower end of the separation vessel balance the velocity heads on either side of the stacks of the parallel angled interceptor plates and eliminates horizontal surfaces which would accumulate solids.
