Abstract
A process and apparatus for spraying a liquid into a flowing vapor stream is disclosed. Multiple nozzles for injection of a liquid are radially distributed about a pipe containing a flowing vapor stream. The nozzles are arranged so that the cone shaped spray pattern from the nozzles is at least in part parallel to and near the pipe wall. The number of nozzles, and the spray pattern of each, provides 100% overlapping spray of liquid droplets within the pipe. The invention can be used to neutralize acidic vapor streams, absorb noxious fumes, or quench thermal reactions. The invention is especially useful in quenching hot vapor streams. Quenching hot cracked products from an FCC reactor in the transfer line improves yields, and permits higher catalytic cracking reactor temperatures.
