FLUID DISTRIBUTION APPARATUS FOR DOWNFLOW MULTIBED POLY-PHASE CATALYTIC REACTOR

摘要

A nozzle device (230) for coupling with a fluid distribution conduit is provided for improving the distribution of an upward or downwardly flowing polyphase mixture including at least one gas phase and at least one liquid phases above at least one packed bed of granular solid or fluidized bed. The fluid distribution conduit for receiving liquid (215) and gas (210) phases has one or more lateral openings for flow over and upper portion of its height through which a gas phase can enter and has fluid distribution conduit having one or more lateral openings for flow over at least a lower portion of its height through which a liquid phase can enter the fluid distribution conduit. The nozzle device (230) is fixedly coupled and co-axially aligned with the lower cross section of the fluid distribution conduit.
