    摘要: An apparatus for replacing particles in a process that transfers particles is disclosed. The apparatus 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. The apparatus 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.

    摘要: Adsorption vessels and systems utilizing adsorption vessels are provided herein. In one embodiment, an adsorption vessel for receiving a fluid mixture and for separating a component from therein includes a vessel wall extending from a bottom end to a top end and defining a vessel chamber. A bottom inlet is formed in the bottom end of the adsorption vessel for introducing the fluid mixture to the vessel chamber. Further, a support plate is positioned in the vessel chamber above the bottom end, and defines a bottom void volume between the support plate and the bottom end. A filler material having a total porosity of less than about 25% is positioned in the bottom void volume and defines a channel for flow of the fluid mixture from the bottom inlet to the support plate.

    摘要: One exemplary embodiment can include a process for pressure swing adsorption. Generally, the process includes passing a fluid through a first channel for adsorbing at least one component while simultaneously passing a stream desorbing a component through a second channel. The first and second channels may be in thermal communication for transferring heat from the first channel undergoing adsorption to the second channel undergoing desorption.

    摘要: Catalyst regeneration vessels including a chlorination zone that includes an outer mixing chamber, an inner mixing chamber, and a catalyst bed. The outer mixing chamber can include a lower portion and an upper portion, the lower portion of the outer mixing chamber including at least one air nozzle that injects a drying air stream into the outer mixing chamber, at least one chlorine input nozzle that injects a chlorine input stream into the outer mixing chamber, and at least a first baffle. The chlorination zone can also contain a second baffle that directs the mixed drying air stream and chlorine input stream from the outer mixing chamber to the inner mixing chamber.
