ABSTRACT:
An arrangement for the controlled production of an essentially linear array of hydrocarbon feed injection jets reduces required clearances and elevation while facilitating modification of the contacting locating a feed distributor containing a linear array of jets at a standpipe junction point to provide choke point for particle flow control. The flow properties of the extended particle layer are controlled by adjusting the density of the particles above the choke point created by the upper part of the standpipe inside diameter and the top of the distributor. Steam or another fluidization medium may be added to the particles directly above the distributor for this purpose. This invention can also modify the particle or feed injection characteristics by changing the projection of the distributor into the standpipe to adjust the flow area over the choke point and by the use of bottom slides or baffles to change the flow area size and configuration. Location of the distributor at a standpipe junction will also typically allow the placement of the distributor at a lower location in the process which eliminates the need to add vessel height for supplying pressure drop for the particle discharge point. The distributor arrangement also fits compactly into most common standpipe junctions. Thus, the arrangement of this invention solves the problem of inserting an extended array of feed injection points into a fluidized particle contacting process without providing a large amount of clearance or additional vessel height.
