We used this technology in our RFCC unsuccessfully on an external riser system.  Need to ensure excellent atomization (nozzle type and atomization media (steam)) on the LCO or naphtha boiling point range quench material and that the riser piping is lay-out is designed properly so that liquid droplets are not classified.  It definetly reduces 1,3 BD and pverall gas make but comes at the risk of coking the gas tube or cyclones especially in a resid unit.
